Sony Bravia Just went out of warranty, of course. Now there is a black bar around the pictures on some of the channels that were not there before. I don't know what happened. I'm not very technical, so I need to know if this is something I can correct or do I need to call a repair person. It's not on all the channels, just some of them, esp. HDTV channels. I am connected to a Motorola "Moxi" box (Charter Cable). Any help is appreciated.

possible bad back light inverter board or broken back light tube. refer to local service tech

if the line is pixel thin, it could be a bad lcd panel. if it is a wider bar, it may be in the video circuitry. many of these sony tvs had bad panels, and sony has extended the warranty. call up sony with your model and serial # and date of purchase and try to get them to help you out, that is your best course of action. let me know if you need more troubleshooting assitance.

Hi,Yes your problem sounds like the DMD board.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens. Here's a video that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q Have a blessed one!

Unfortunately, this has to do with the way each channel is broadcast. Some have gone to 16:9, but some have not (even those in HD--See ESPNHD for one example). Most TVs have a way to "strech" the picture somewhat so you can fill more of the screen, but of course then your image may be distorted. I agree that they grey bars are annoying; I wish they would go to a true black.
Sorry I couldn't be more encouraging. Enjoy your TV!

yes humidity has been known to make the panel seperate. I live in south tx and work for sony, alot of panels that show that prob is usually the panel seperating. wouldnt recomend to fix to costly around 85% the cost of when you bought it.

Did you hear any pops before the screen went black?
You've tried completely discharging it? Disconnect everything off the TV, all cables and power.
Press and hold the power button on the TV for at least 20 seconds.
Let it sit, and in about an hour, plug just the power in (directly to the wall) and see if it comes on. There should be an indicator light, is it white or orange now? Was it a different color before?
Odds are it's a board, be it the main or a video, don't know for sure. If you can take the back of the TV off and see if there are any evident signs of damage, blown or swollen capacitors, burnt traces or resistors/diodes, etc.

try another tv

Yes, I had the same problem, it happened after 14 months of my purchase, or just 2 months after expiry date of warranty. But remember they have 60,000 hours warranty on screen and this fault is part of screen (no picture J it is screen problem), I called LG, first they did not accept the claim but soon after I mentioned that I have done many research and this is very common problem due to use of faulty part or unreliable design, and if they don't fix it on their cost I will take legal action, one of the supervisor contacted me and after saying LALALALALALALALALALA accepted to send someone to fix with no cost. But I have found out they did to many others whom take this mater serious so it was not just me alone J They are aware of using faulty part is some ranges of their products and now this common problem appears, LG don’t like it and wants to somehow get away. ((((((((((So don’t let it happen))))))))) some of us paid around $5000 to $7000 when this TV came out, recently price went down to around $2000. CALL THEM and ask FIX or COURT? For sure they fix it for you free of charge J Imagine how much would it cost them to recall all TVs which they know is faulty?
Enjoy

Hi Janet, Could you provide the number of your repair service. I have the same exact issue and I am unable to find a service repair technician who knows how to do this!
