Found a huge flatscreen:42" in the dumpster. It does not seem to work (no LED, no response). How to go about?

This TV would be awesome if it can be brought to life again! no need to build a beamer (video projector)!

Would mounting a TV inside a piano damage the TV?

We have an upright piano, and we don't have a good place to put our flatscreen. My thought is to put the flatscreen inside the piano. I have measured for clearance and it fits quite neatly. My only concern is if the vibrations from the piano will somehow damage the TV's electronics. On the one hand, the TV has speakers and generates a dynamic range of sound and volume and does just fine. The TV can get louder than we ever play the piano. On the other hand, the piano sounds are fuller and maybe vibrate more than the speakers in the TV do. More details: The vertical board behind and under the keyboard has a latch that is opened so that the board pivots down and forward.  The TV would go inside the space behind this board. It would make the TV close to the ground, but it would be more convenient than the current location. The space in the piano has a depth of about 6 inches. I would install a piece of 3/4 inch ply across the back to mount the TV to. It would be right in front and possibly touching  the sound board and the bass bridge. The TV is 4.5 inches deep at the deepest point. I am sure that the construction is feasible and well within my abilities. I am unsure of any danger to the TV from such a setup. Any insights, references or suggestions are well appreciated.  Thank you, Michael Moore

need to built a telescopic bracket system for my flatscreen.

I want to use my TV as a monitor as well. But I need it to height adjust on the wall about two feet, for the two different uses. No pre-made brackets that do this...any idea what to use to build it? I'm assuming that it would be a  flat screen bracket that can slide up and down on some sort of rod or pole secured to the wall. Not sure what system to use to be able to secure it at the two different heights. It's a 22"....  It seems a waste to not be able to use it for both and clear out the monitor I have now.  Any suggestions are appreciated.

THREE-DEE VIDEO from multiple lcd panels.

This morning I was watching television and thought to myself, "Wouldn't Good Morning America be so much interesting in three dimensions? This got me thinking, and I came to this idea: what would happen if you dissected a bunch of lcd monitors, removed the backlights, and stacked them. Then, you plug all of the screens into a processor that generates an image for each screen, and have a powerful backlight to illuminate these screens. I know that it is quite a stretch, but if one could work around issues such as the amount of heat produced and the cost of production, I think this could work. I think the best bet for input would be using RGB or CKMY on multiple panels, but I am not an expert in optics or any of that. So basically, this is an outline of what would need to happen, as far as I can tell: 1. A group of LCD panels that, when in a cascade formation and are fed sufficient data, produce a three-dimensional image 2. A bright backlight that is capable of illuminating said LCD group 3. A video processor capable of sending multiple signals to the screens that would produce a three dimensional image (as stated in point 1) 4. A cooling system to maintain component functionality 5. A benefactor or deep pockets 6. Lots of spare time If you have any ideas, please add them, I'd love to hear from the Instructables community.

How to run a 20" flatscreen tv with a portable power source?

I'm wondering how to run a 20" flat screen tv on a portable power source. Would something like a car batter work? Or like a billion 9 volts? I need to be able to take the TV outside and walk around with it for about an hour at a time.

Can I connect the output of the recorder ( BNC ) for my wireless security cameras to an LCD flatscreen monitor ?

The flatscreen monitors I have seen have d-sub connectivity. My recorder has a bnc output ( analog?) connection. Manufacturer says the output can be sent to a tv set so I assume it is an analog signal. I want a nice size screen but small unit than a tv set for desktop. Can this be done?

Design Assistance Humbly Requested! Mylar + Flatscreen TV + Frame = Stealth TV Goodness

I am in the pre-panning stages of a project in which I would like to make a false over-the-mantle mirror to hide an LED TV using mylar on a motorized roll to pass over the television.  I will be building a frame and really need some brainstorming help with a starting off point for fabbing the mylar into a false mirror.  Parts, ideas, etc.  from a very simple, mechanical-tension model to more complex, electrically motorized design would be much appreciated. Thanks!

What makes your tv start having little white dots all over the picture on the screen, and how to fix?

I have a samsung flatscreen tv and about a month ago i noticed a couple white dots showing up in the picture, and every day more shows up. Any idea what this could be? i was thinking something with the pixels, but not sure.  Any advice would be helpful.

HDMI blackouts?

Hello, i hope someone can help with this problem, so far all the experts have failed. When i plug in my laptop to the flatscreen to watch a film it's ok for a while then the big screen goes back, it starts to reoccur with greater frequency. What i have found is if i unplug and replug the cable it lasts really well most of the time. i thought it may have been a capacitance issue but the fact is its pretty good once replugged. What can i do?

How do you play audio through both internal speakers (Like an iMac's) and through the headphone port at the SAME time?

I recently purchased an iMac, and I have it hooked up to my flatscreen. I bought an audio cable to connect it along with the HDMI, and is connected through the analog (headphone) port on my computer. I want it to route sound through both internal speakers as well as to my audio cable, but so far I have been unable to locate or acquire the software or settings panel needed. I am running Vista Enterprise 32 bit.

Hey, let's invent this immediately!!!

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

Less then 2 yr old flat screen - has died....I believe...

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.
