Sounds like you need an inverter board which is the power supply for the screen lights. I tried to look up the part but samsung dosen't have a service diagram posted for it yet. Since it is so new you may want to find a samsung authorized service center because if the part is not available yet Samsung will have to solve the problem.

SOURCE: sony kp-61hs10 tv, has sound but picture goes black after 3 min.

I just had the same problem. If your lucky it might be a free 5 minute fix. The five light flashes mean impropper current. I took the front grill off, then behind that is another black cover, I took that off and noticed the circuit boards COVERED in dust. I then took an air can duster and blew off all the dust... works like new. No more flashes and in an out picture. The collection of dust was interfereing with the electrical current.

Sony Wega's are noted for having a bad lamp and a warped lamp door due to heat. I recommend replacing the lamp and the lamp door. You can find both of these at www.fultonelectronics.com and also www.encompassparts.com . You can do these yourself with ease.

Projection TV no picture flashing horiz arcs across top of screen sound okay


You will need convergence work to this unit. Not cheap.(Not recommended for DIY unless already experienced in this type work). Might contact a local servicer experienced with Toshiba & see if they can give you a quote over the phone. Be sure you are sitting.
This is probably a good time to consider entering the 21st century & look at LCD or LED flat screens.

Discolored Sides


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.Ths if your tv is a dlp if its a Lcd it will be an issue with your light engine: Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine. Have a blessed one!

Don't waste any time on this. Being only 4 months old, it should still be under warranty. Request warranty service or exchange. The power supply module has a problem or the main processing board is telling the power supply to shutdown. In either case, a board change is necessary and should be covered.
