broken led tv uses?

I have a 32" Visio led with a cracked screen, way too expensive a repair to justify going through with, but I want to utilize the parts for other projects if I can. the tv was brand new so all the boards, LEDs, speakers, wires, etc... are in perfect condition and I was wondering if there is anything cool I could do with them. I was thinking about rigging the boards up to a 7" LCD screen I have and installing it in my car to add tv/DVD/audio in/hdmi/USB to my dashboard but I'm not sure how to go about connecting the 30pin LCD monitor cable to the componant screen input.  anyone have any ideas on how to do this? or anything else I could do with all my newly acquired parts?

Reuse the LED from a TV Question?

I had an LED Tv break and I decided to remove the LEDs out of the TV and reuse them as background LEDs for the new TV.  The issue that I am running into is that I can't figure out how to power them on.  I know they work because i can get a segment of 3 to light up by using wires connected to a 12v battery.  Each strip has 57 LEDs and a 4 wire connector.  I was guessing that this means it is a RGB strip, but there are nothing but +/- symbols on the strip so it is confusing as to what the wire does what on it. I would appreciate any help that anyone may have for me.

Externally Mounted LCD/LED TVs?

I was going to wrap my 1996 Fleetwood Seawind Motorhome and have sponsor spots.  However, I rather hang 55" LED/LCD TVs on both flanks of the beast. The issues as I see them are as follows: How to power the TVs--I think I can cable out the rear windows and run an inverter to provide them with AC--Please give me inverter size sufficient to drive two LCD/LED units Getting a TV signal to the TVS.  Using a Macbook Air, I could use Airplay to stream MP4 video to the TVs, or just hardwire them with HDMI-Lightening connectors.  A hardwire solution is, again, possible via the rear windows. The pivotal engineering riddle is ho to secure, insulate and protect the units on the back end of the vehicle.  I was thinking a sheet of Acetate to cover and protect the faces of the TVs. Input on what form the shock-absorbing, waterproof frame could/should take is welcome.

Trying to turn on and off leds with tv usb

I have LED lights in the back of my tv ( ambilight ), but they stay on when the tv turns off . What I am trying to do is to turn off with the USB on the tv with a relay . I'm thinking if it is possible to use the 5v from the tv usb to power the relay so when the tv stars it gives power to the usb , starts the relay, that is connected to the "+" of the leds and makes the connection to turn on the lights. My question is i'm not a electronic guy and I don't know if it will damage the tv or the lights . should i use something else like a diode?

i need help picking out a TV?

i want to buy a 29-37 (preferably 32) inch TV that has Internet Apps; (maybe 3D); at LEAST an 80,000:1 contrast ratio, (maybe 120 Hz or more, but I'm not very picky as long as there is no flicker on the image); and 1080p full HD. i found many models rounding at about $900 (without 3D, of course), little pricey huh?   my QUESTIONS: 1) picture-wise, what is the difference between "back-lit LED", and "edge lit LED" and is there any other technology i have not heard of yet (NOT including back projection of a projector)? 2) which would be the best choice LED, LCD, or Plasma, (of if cheap, small and light enough,      back projection DLP)?         (i don't really care about efficacy, but i do want one with a good lifespan; really bright colors     (like led or plasma) and good contrast, and has deep "black" blacks; hopefully 1080p, but     ill settle for 720p, less than 8 ms response time; has a great viewing angle; and last and     certainly not last, one that is under the $1600.00 price tag!) 3) whats the difference in the picture quality with edge-lit-LED and back lite-LED? (i know the led      placement in each corresponds with the type of led tv it is.) ____________________________________________________________________________ right now, i have a 19 inch CRT 4:3 aspect ratio (i am guessing 480p res) the TV itself is a "CurtisMathes-Tronics" brand (i never heard of it) (model # "CM 19022S"). its OK. it works, but its getting too small for me, and after i bumped into some money last summer ($700) at the peek and i am thinking saving for a "state of the art" HDTV! next year, with my summer job, i should have $1500 to spend.

Projection TV, all in one entertainment center

I have been playing around with the idea of a rear projection TV as a full all in one entertainment center. As most know rear projection TV's are large and very hollow. My idea is to add a mini-ITX motherboard, a Hard drive, a webcam, 2 USB ports on the front, an IR reciever, and a multi-microphone array. I may also add IR emmiters for use with a will remote, audio ports for a surround sound system, Light sensors to adjust brightness. My TV also has a Memory Stick reader that i want to use for the computer instead.  The motherboard and HDD fit in the base just right with plenty of room to stack a few drives if needed. and there is plenty of room for other accessories if needed. There is a door on the front of the TV with an extra input, with space for USB Ports. The IR reciever for the TV I think should fit a second. If not I will use some sort of repeater to split the input between the 2. although the TV's remote may not be needed at all. The Micro ITX board I have been looking at has a mini PCI port with a laptop style WIFI card, I plan so get some of the antennas used with a laptop and mount them as close to the top as I can get them. and maybe add a bluetooth/wifi card as well. The camera will be an internal laptop camera mounted at the top. The light sensor will be mounted ether on the front or on the top. (I think front will be better.) The microphones will be mounted on top near the camera. One on ether side. Thats the easy stuff. The hard part I want is for the computer to turn the TV on and off with itself. This requires something that will look at the state of the TV. (using the power LED inputs) and close the power button for a second if it needs it.

LED Suit of light

Hi, I am looking to build a fancy dress costume, and have approximately 12 months to make my costume :) What I would like to build is a replica of the following (or something similar): http://www.gizmodo.com.au/2012/02/night-snowboarding-in-an-led-suit-is-mesmerising-to-watch/ I have searched for flexible fabric with woven LEDs, i have also searched several suppliers on Alibaba for flexible led mesh screens but nothing seems to be quite suitable. I think, for this, i would maybe be best off building the suit from strips of waterproof 5050 SMDs like this: http://www.alibaba.com/product-gs/615439688/business_agent_smd_505_led_strip.html Power would be in the form of the biggest 12V power supply I can find. The only problem here is that at full brightness, the suit is going to consume A LOT of juice... I have seen this costume which is similar in construction, except all the LEDs twinkle (like TV static): www.youtube.com%2Fwatch%3Fv%3DLal9uma1iVc&ei;=nwgtUNT7B6_Z0QXekYGwDA&usg;=AFQjCNENmYUCu_AwYaEAwqAiWSDFRFnUeg&sig2;=FXRYO81ccZavpYyeBsZMyQ This has the added advantage of lower power draw as not all of the LEDs will be on at the same time. I actually much prefer this concept, however I have absolutely no idea where to begin on schematics... Any insights or friendly advice from the experts would be handy, I have a rudimentary knowledge of electronics, and am very handy with soldering. Thanks!

i have a tv that doesnt light the backlights, how should i go about fixing it?

Its a 40" Haier LCD TV, me and my dad picked it up at a disposal place, when we brought it home and tested it we figured the tv had some issues with th screen, we feared it might be like the 26" tv we got that just turns on and shuts off. luckily, it does not have such a issue, i checked and it is just the backlight that has a problem. and, from further investigation, it appears the ccfl's are not getting any power from the inverter board. the inverter is split into two parts it seems, there is a lrge inverter looking component on the power board which has two wires that connect to the board the ccfls connect to, which has numerous smaller inverters on it. a interesting discovery was that the to wires from the larger inverter piece get bridged when they reach the sub-board. im assuming its the board with several smaller inverters, because it is getting -12v of power, im not sure if thats normal but ive never seen a inverter setup like this before so its hard to tell. my camera battery is dead at the time of this post but i wil get pictures put up so people can see what im dealing with. the tv was made april 27th 2009. it has 8 CCFL's in it, which seems like a lot but im not exactly sure. so i was wondering what the most efficient way of repairing it would be: -replace possibly damaged inverter board with a new one -replace CCFL's with a LED light strip (im leaning toward this) -replace bad inverter board with a set of replacement inverters (8 in this case) what do you guys think?

LCD TV Display or Monitor for Security Camera

Another tech guy at my school and I were thinking of buying this camera for the auditorium. The light/sound booth is off in a back corner, and due to a not-quite-big-enough window, it is almost impossible to see any activity on the stage when it's dark. This is an issue for when, say, we are supposed to turn on lights as soon as someone's onstage. We already have plenty of hiding places for it in the ceiling, and it had an array of IR LEDs, to further help it see the stage.The problem is a monitor. It has composite RCA output, and we need to find something that will display it. It doesn't need to be big, as the booth is just barely big enough to fit three or four people in. However, we would like to find an LCD, because we don't have much room for a CRT. Also, if you haven't guessed already, it has to be pretty cheap. I think I saw a display a while back that was a 10.4" LCD with RCA input and no tuner for under $30, but I can't remember what it was called or used for, much less where I saw it. Does anyone have any ideas where I could find an LCD display? Spambots need not apply...

To help make sense of it all, I thought I would try to pick out 10 of my favorite LED instructables that are great for the LED beginner and the expert alike. This list isn't hierarchical - I like all 10 projects. Instead, it's loosely arranged in ascending level of complexity, so newcomers to LEDs might want to start at the beginning and work their way up (or down as the case may be).Drum roll please...1. LEDs for beginners is a first time guide for anyone looking to learn a little bit about how to wire up one or more LEDs.2. How to solder is a guide that explains how to solder wires, electrical components and more and assumes no prior soldering knowledge. If you're going to work with LEDs, chances are you'll need to do some soldering, so this could be a useful place to learn some skills.3. LED Throwies is a super popular and simple instructable that shows you how to take a magnet, a battery, some tape and an LED, and make a cool light that will stick to anything magnetic.4. Fridge Lights is an instructable that shows you how to turn your refrigerator into a canvas for LED art. It has a little more involved in it than LED Throwies because you have to prepare your refrigerator surface a bit, but its still a great project to get started on working with LEDs. 5. LED Football is a simple project that embeds LEDs in a Nerf football so that you can see it in the dark. The football emerges from the process relatively unharmed, and from the pictures it looks a lot like a cool flying saucer.6. LED Bikelight V2 and How to build a 1,024,000 mcd portable light take multiple LEDs and wire them together to make high power bicycle lights. There are many bike lights on the site besides these two that are also great, but I like these two because they are really BRIGHT. 7. Blue LED Light Box is a bedroom light that helps combat Seasonal Affect Disorder (SAD) and the winter blues by letting you bask in 18 watts of LED power. If you like the first iteration of this project check out the Blue LED dawn simulator for Soleil Sun Alarm add on that controls the brightness of the LEDs according to a dawn simulator alarm clock.8. Spoke POV: LED Bike Wheel Images is an instructable that puts LEDs in motion and creates persistence of vision (POV) images of your choice right on your bike wheels as you're riding. If you have never seen POV images before you should definitely check this out as there are a bunch more POV instructables on the site. It's a public mobile display for your bike!9. Watch futurama on an 8x8 pixel screen shows you how to make an LED display that you can use to "watch" tv on. While the actual display doesn't have enough pixels to actually create a recognizable image, I like this instructable because even though I work with technology, I think I secretly want to live like a caveman, and it's this kind of forward thinking backwards technology that gets me going.10. Microdot - wrist watch LED pattern timepiece is an instructable that shows you how to build a unique LED watch. It's one of the more advanced LED projects on the site, but rgbphil offers good support in the comments section and should you decide to build it ever you'll end up with one heck of a watch.Instructables HQ is going to be mailing stickers to the authors of the projects on this list as a mini prize for making great things with LEDs. Anyone else who makes a list of their favorite instructables and posts about it on the forums gets stickers too!

Anyone know what this is?

I just got hooked up with digital tv today, and www.wegener.com/PRODUCTS/STREAMING_MEDIA_DECODERS/SMD_515.php these are what they gave me for set top boxes. Little IPTV streaming boxes. I noticed there was a spare led labeled HD on the front, and upon further inspection, I found a ide connector and a power connector for a 3.5 inch hard disk. Normally my isp would want me to rent a different receiver for PVR functions, and additionally a lot more per reciever. This box can use a hard drive, but when I put one in, nothing happens when I plug it back in. Now apparently, from what I've read, my isp might have installed their own firmware onto the boxes, but I do not think that is the case, the menus look like the one's I've seen online. I expected for there to be an extra option pop up in the menu when I powered it on with a hard drive installed, but that was not the case... is it the format? I have a 40 gig in there (for a tester) formatted as fat32. What am I doing wrong here?? Oh yeah, and theres a screenshot I got off my tuner card, it only shows this "boot" screen when you unplug the power and plug it back in, otherwise when you switch it off, it seems to go into a "Soft-off" mode, and the hard disk I noticed also continues to spin after it's been turned off... I don't like that :S Anyways, I can't find anything online, so much as a quick reference manual on wegener's website, but it didn't provide anything useful, it vaguely mentioned the recording function, but nothing of installing a hard disk or setting it up. I assume there should be SOME kind of menu/setup I can get into to setup the hard drive/view more options other than the audio format and some other minor options I can currently see like menu appearance. I'm super fascinated to see if I can get a hard drive actually functioning on here, like the remote even has a record button on it, so obviously it was meant to be a pvr, just they expect you to pay them out the nose for them to put one in for you.

Display website outside on a large LED/LCD Monitor

I want to be able to display a webpage on to a large monitor. (so people can view the site when they are outside for example) The website would update in real time (ajax based) but is essentially pretty basic just some images and text (no flash)/simple design. I have had a bit of a look around at supplier sites and most seem to have their own system where you can add in images/videos to display, or a program where you can input data yourself. I was looking at was something like Samsung smart TV but I think this is to good for what I need as I want to keep the price down, or Opera TV but I am not sure if I am looking in the right direction. I don't really want to have a lap top connected to this device (and be connecting via a cable) ideally you could talk to the device via a smartphone over wireless/bluetooth. I don't know where to start but I reckon if someone could point me in the right direction here I could make my idea happen?
