I have a nice 22" LCD monitor here, its a SCEPTRE X22WG-1080P, the monitor originally wouldn't get any signal at all. After opening it up & blowing it out, reseating all connections the monitor will turn on now, but it simply won't respond to anything. It flashes white, red, blue, green, black, etc in a repeating fashion. Anyone have a clue to what the problem is & maybe an instructable to fix it? Thanks!

I have to sit sometimes and stand sometimes to use my desktop computer. I use an old, heavy, jumbo-sized CRT type monitor which has a space-saving stand on its top for my printer. Currently, when I stand, I raise the mouse on a box and elevate the keyboard on a piece of foam and I peer downward to look at the monitor. This is not always a good way to see everything on the monitor. What kind of simple elevating/lowering platform could be constructed so that the monitor can be raised to be level with my head when I stand and lowered when I sit in front of it? I suppose some electrically powered or non-electrical hand-cranked platform would be fine. Remember: both the motor, hardware and platform have to be able to lift, lower, and support a heavy CRT monitor which has a plastic platform holding a printer above the monitor. [Due to severe space limitatons where I live in my ultra-tiny apartment, I can't really use a shelf to hold up the monitor when I stand, and besides, it would be a pain in the neck to frequently lift/lower and set in place the monitor on either the shelf or on the desktop.] Thanks

Hello, So for my application, i need to have a circuit that can monitor the input voltage until it reach 5V (usually from 0V ) then switch on and allow the 5V to flow into another circuit. The problem is i have no idea where to start. Can anyone help me ? Thank you very much

I've got a 19 inch flat screen crt monitor hooked up to my mac. And when I play my music really loud, the image almost shakes like it would if I had the stereo hooked up to the power bar with it like it used to be. The stereo is on it's own breaker right now, but is it doing that from the actual vibration of the picture tube or is it dieing on me?

Hi everybody! As the topic suggests really i was wondering if this can be be done. In particular so that they could be fitted in to a car for a dvd player. It seems as though it should be possible but i was wondering if anyone had tried it?

Hi all, I am working on a project to create my own portable usb monitor (eg. ltn101nt02) and a LCD controller board. However, the controller board requires a 12v power input with more than 2A. I am thinking of using a boost converter but I'm not sure if it will work. Also, with the USB as power input, can it still work as a screen input for my monitor? Can anyone advise if i can modify the board such that I can use a USB for both power input and screen input? Thanks!

I have a very large and very nice silicon graphics monitor, but the screen marks very easily. It's coated in something purple that I assume is some sort of anti-reflective coating. Basicly the problems are that pretty much anything that touches will mark it and the marks are occasionally difficult to remove. Cleaning it also leaves smear marks that can only really be removed by rubbing the screen quite hard with a cloth and crap just seem to collect around the edges. I've tried water/soap/petrol/alcohol and pretty much anything else i can get my hands on but nothing seems to work. Any tips?

I turned my monitor on this morning to be greeted to some weird shit. Apparently everything towards the bottom is squished and the top is stretched out. It's not really bad but you can definatly notice it and I'd like the know why it was fine last night and not this morning. I degaussed it and nothing, any ideas? Or has this thing finally bit the dust?

Is this possible? I'm trying to run RCT3, and my dinky screen can't handle the incredible graphics...so I'm trying to make another monitor that can handle it the only monitor. Is it even possible to disable the lcd monitor that's built in? If so, how would I do it?

So...can this be done? I have a Mimo USB monitor that I'd like to connect to a webcam (sans computer) to use as a viewing monitor. Basically the camera will be used for tele/micro/macro purposes and the image would be sent directly to the monitor. An example would be to attach the camera to a microscope and then use the monitor to view the image, rather than peering into the viewfinder. All this would be battery-powered so that it's usable anywhere. However, I don't have a the slightest clue how to bypass the whole computer thing, as I can't find any info on how the USB monitor works. The Mimo is actually a touchscreen with a builtin video card, so it should be capable of some cool hacking. I have an old usb webcam available, as well as a tiny spycam with RCA out. Questions: Can the USB camera or RCA camera be connected to the Mimo without the use of a computer? Has anyone seen this done before? Anyone have any links/suggestions/experience with this idea?

Has anyone found a way to power the backlights from an LCD monitor? We have a bunch of monitors at work that are dead and I'm pulling parts from (the plexy-glass is a very nice score). I'm getting a few of the mini backlighting tubes, along with the power supplys, but can't seem to trick the power supply to come on. I thought of a few good projects but can't figure out just how to get the tubes lit (without blowing them up )....anyone out there have any input? (sorry for the pun)Scott

I recently bought a 19 inch LCD monitor for 40 bucks (used). It works perfectly for about half an hour (i havn't timed it) and then the screen just goes blank. If i turn it off and then back on it works for a couple of seconds then it turns back off. If I let it be for a while (like an hour or just when I'm not using my computer) it works fine for another half hour. Is this an overheating problem or what is going on?

I bumped my lcd monitor with a hard object (keyboard) it did not crack but there is darker (from wide angle looks brighter) spot in the place that got the impact. its a smooth spot and not bunch of pixels it was very severe. i played with my finger on it and pulled it lightly with electrical tape (stick and pull) and now it is much less severe but it is still there can it be fixed anymore ?

Hi Everybody. I just bought a Dell ST2420L flat-panel monitor to replace my old 2405FPW. It's a better monitor, but its base is terrible. The old monitor's base could be raised and lowered by several inches, the screen could be rotated 90 degrees, and it tilted farther. The new base isn't adjustable vertically, won't rotate, and tilts only a few degrees. I was hoping I could mount the new monitor on the old base, but the mounting hardware is all different. The attached pictures show (1) the 2405's base with mounting bracket removed, (2) the 2405's mounting bracket, which bolts onto the base, (3) the place on the back of the monitor into which the mounting bracket slots, and (4) how the ST2420L connects to its stand (I'd rather not take mine apart to photograph, but I'll do it if anybody who wants to help needs to see the hardware more clearly). I wonder if anybody has successfully adapted the base of a 2405FPW to mount an ST2420L or similar, recent monitor, or anything similar? Or would be interested in taking on the project? Thanks for any help or ideas. Regards, Jim Crutchfield Long Island City, NY

I have a Lenox brand 7" wide TFT LCD color TV model TFT730, it's not much good to me as all of our TV signals are now digital and this unit has an analog tuner. Would it be possible to convert this to a computer monitor? I'm pretty good with a soldering iron, I just need some help with connections and if required, some sort of interface circuit? Any assistance would be appreciated

I have huge 21 inch crt monitor which i found yesterday in the trash i plugged it in now. it works but the image has some distortions the color that should be black is bright gray and all other colors are like addition to it. the image looks very bright and with bright gray tint. setting brightness and contrast to minimum does not help much there are some kinda scratch lines across the display. the lines form a shape of a 'lightning' with horizontal lines and diagonal that connect them. the density of lines is higher when i switch to higher resolution the image size is severely affected by the brightness of what is displayed. it grows larger about 1 cm on each side when i open a window with white background other than that the monitor works ok in all resolutions from the bios screen and up to 1600x1200 what can be the problem ?

I'm rebuilding my entire basement office this summer and I've had an idea for a really cool tablet substitute. I'd love to be able to mount a monitor in my desk and get an overlay for it to allow for me to use a tablet pen on it. I have a vague idea of how I want to do it, but I'm hoping that you guys can help me come up with a sturdy way of mounting it in the desk and where I can get an overlay that isn't touch sensitive (this is going to have my hands on it when I'm typing, then when I need the tablet function, I'll move my keyboard over), but responds to a pen. Thanks for helping!

I've been browsing around the site and see plenty about converting old whole laptops into picture frames but I'm hoping to make a digital sign to play video and such and am, so far, unable to figure out how to change the projects to work for my purposes. I have an old laptop monitor that is no longer attached to its original unit due to manufacturing defect and I hope to convert it to a digital sign for the front window of the student union office at my college. I thought it best to ask here before trying to convince the electrical engineering class. xD Thoughts? Insights? Links to instructables that might assist?

OK folks, how hard can this possibly be?Yeah, yeah, I know. Probably REALLY hard. But if we all team up and combine our gray matter, can't we overcome any technological obstacle with our collective geekiness?I want to see an affordable, open-source doodad that can turn an LCD from a dead laptop into a working external flatscreen monitor. It should accept digital & analog signals and allow us all to hack up beautiful screens ready to embed in our brilliant projects, while keeping LCD's out of the landfill.punish3r valiantly went down this road: https://www.instructables.com/id/Laptop-Converted-to-2nd-Monitor/but then ended up "cheating" (his words, not mine) by using software that does most of the work (plus he started with a functional laptop!). Discussions I've read usually end with "you'd have to buy a controller for that specific LCD, which would cost almost as much as a regular flatscreen so what's the point?"I reject this (resting on my laurels of ignorance)! If a controller truly exists for every LCD on earth, don't they share lots of common features? And if so, can't we come up with a generic one that could be programmed or dip-switched or soldered or otherwise persuaded to play nice with any LCD on the playground? Even the weird one by the monkey bars who smells like cheese? (Sorry; stretched my metaphor too far and it broke)I envision a circuit board with PC or even TV "in," an amazingly versatile multi-pin adaptor or cable that would replace or connect to that flimsy little ribbon cable sprouting from the LCD. The board would have a USB plug for programming, and a chip smart enough to remember what you tell it. Some smart person will write a nifty app that talks to the board, and vast legions of techies across the globe (or rogue employees of the LCD manufacturers, perhaps?) will upload specs for all of their LCD panels that will be used by other smart people to create a profile for any given panel that can be dropped onto the board.It would have to be really low-cost to make sense, but I envision a cottage industry: package it up as a kit, or we could build goofy-looking monitors out of e-waste and sell them!Somebody else could probably strengthen the argument in favor of this invention by providing a list of terrible LCD ingredients that would be re-purposed out of our trash heaps and water supplies and cat food... I'll leave that up to the experts.What do you think, folks? Is this a pipe dream, or a viable idea? Either way, let's do it!(and if anybody manages to make one, I get dibs on a prototype!)Thanks for reading!Mike

The community has a water tank on the top of the hill and a pump about 1/4 mile away, nearly line of site. There is a float in the tank that used to send a signal down a wire to shut down the pump when the tank was full but the wire has since corroded and is no more. They do not want to run another cable. We are thinking that a solar powered radio transmitter at the tank could operate a shut down receiver at the pump. (The pump has AC power but there is no power at the tank.) Anyone have any ideas how to make this work?

I bought some of these http://www.amazon.com/gp/product/B000IF6URO/ref=ox_ya_oh_product and would like to wire up a usb gamepad to detect the siren as a button press. I'd assume this should be very simple the relay will connect to the siren speaker. I can then write an app to email/text message me if the sensor detects water on my kitchen floors.I'd like to know what kind of relay to use (how much power, an exact one would be nice), I just need a momentary circuit close (similar to pressing a key).I'm a programmer with a limited knowledge on circuits.

I have a typical CCFL-lit LCD backlight that I tore out of an ancient, dying laptop with an ancient, dying screen. The backlight is roughly 25.5cm x 19 cm (9 7/8" x 7 1/2") and about .5cm (1/4") thick. When around 18VDC is applied to the inverter, the whole rectangle lights up with a perfectly even, white, light. I've been trying to come up with something cool to do with it. So far, these ideas have included: -With a piece of protective plastic, a small lightbox for tracing or viewing negatives/slides -Mounted over a desk for a really cool lamp -Illuminated sign Does anyone have any brilliant ideas for what to build with this? A project worthy of the geekiness or the materials?

Hello everyone! I am working on project that involves mounting a 19in LCD monitor onto a board. The monitor has 4 threaded holes in the back for mounting onto an arm or wall mount. I was wondering if anyone knows what kind of screws to use or has any advice on properly and securely mounting the monitor. The monitor is a Westinghouse 19" LCD. The whole project is going to be a small entertainment center for my monitor. I am going to attach speakers and accent lighting. I am doing this for a class project and drafting it in Vectorworks. *If anyone is interested in looking at the plans I will send them to you; however please don't redistribute them. They will be in DWG format. GC

Congrats! Instead of throwing away your broken LCD monitor, you've decided to fix it. What do you have too loose by attempting the repair yourself? It's already heading for the trash can or the e-waste center. By repairing it you will probably save from $100 to $200 or more! If you have done any reading at all on the web, you have already discovered that bad capacitors account for a large percentage of all LCD monitor failures. If your monitor flickers when you start it up, the screen is dim, has strange lines on it, clicks, etc., then this information is just for you! The repair does not require any special knowledge or skill. About the only tools you will need are a putty knife, a screwdriver, a pair of pliers and a Radio Shack soldering iron. Without getting into too much technical jargon, there are two main components inside your monitor, the power board which powers the inverter (lights) and video, and the video board. The power supply circuit board must be removed before you can replace the capacitors. You must open your monitor and examine the capacitors on the power supply board. Each monitor will have a power supply circuit board. Each monitor model will have a slightly different board. They all look about the same. Some have more capacitors, some have less. Most all LCD monitors have a large 400v capacitor. These rarely go bad. There's a video at www.youtube.com/watch that shows you how to disassemble a Viewsonic monitor, and install new capacitors. This is a great video! There's also a good tutorial that shows how to completely disassemble a Samsung 204T LCD Monitor. It's a step by step guide, which also includes a "how to solder" video. Although this tutorial is for a Samsung 204T LCD monitor, the information found here can be applied to almost any monitor. Between the YouTube video on the Viewsonic monitor and the tutorial you should have no problem installing new capacitors in your LCD monitor. Good Luck!

I have this digital photoframe lying around. It has no input other then a SD card slot. When I look at the datasheet (somehow I can't upload the file, but you can find the datasheet here) I see the different functions of the screen connector pins (page 5), including: Blue Analog Video Signal Green Analog Video Signal Red Analog Video Signal I was wondering, is that somehow related to the RGB from a VGA signal, since VGA is also an analog signal? Would it be possible to connect the RGB from a VGA cable to these pins to use the photoframe as a (lowres and slow) external monitor? I guess it's not as straight forward as just attaching 3 wires is it?

I have a 19" LCD that I use as an external monitor for my laptop but I would also like to be able to hook up my SNES to it and play some of my old games since my only TV is a little 13". Does anyone know how to make a box that has inputs for RCA video and coax cable and outputs video to a computer monitor (with DVI conection). I know there are emulators on the internet that I could play on my computer but it's just not the same without the SNES controllers.

My 17" Gateway flatscreen went blank this morning while I was at meeting. My wife claims she didn't do anything.....that it was blank when she saw it. It was not in sleep mode, nor was a screen saver on. I noticed the "power button" which is normally green (power up, with computer signal) or amber (powered up w/out signal), would not come on. I attempted to see if any of the adjustments on the side might have been bumped, no effect. I tested to make sure there was power from the surge protector (switched power outlets after a shut down) to no avail. After my 4th reboot, I subbed in my old monster sized 17" CRT tube monitor, and it works fine. Resolution is different, but it works.....but that pushed the monitor about 2 feet closer to my nose then I would like (it is about 10 inches from my face. )Did I miss anything as far as testing the monitor before replacing it? I personally think the PSU in the monitor went on the fritz, but I am open to suggestions. EDIT: The old CRT is now back ni it's storage area, and the newest LCD screen is up and running.

Hi all, If you are looking for a way to be notified when one of your instructables gets a spike in more views, I wrote couple different python command line apps for that exact purpose. The first displays a visual notification, speaks and announcement, and plays a beep whenever your tutorial gets X more views. You can customize X. The second uses email notifications instead of text to speech. The third command line app lets you customize the notification ringtone. Hope you find this useful! There'a a full tutorial here: https://www.instructables.com/id/Instructable-Hit-Announcer-Bot/

What would be the best way to make a wireless display? A display that can be carried around (within like 30ft which seems to be fairly standard for wireless). It would need some batteries to power it I imagine, but I have no idea how you would go about sending and receiving the video signal. If anyone has any ideas, that would be great! Not a laptop, just a display, no other functions.
