SOURCE: 5 mostly green verticle lines on all digitle channels. HD ok.

I just called customer support and my issue is now fixed, to my extreme surprise.

It sounds silly (and a tad embarrassing), but here's what I did:

1) Unplug the TV
2) Wait 30s
3) Plug the TV in
4) Test

Apparently even if the TV is "off" for a few days it never fully shuts down unless the power is unplugged. Not sure if this will help anyone else, but I had the exact same problem others are describing. Good luck!

Its your Lamp if you have sound and no picture.
CK the lamp Fan make sure it is running.
Lamps Prices depend on where you buy.$85.00 up to $300.00 Look on E-Bay under Electronics/ Lamp number-BP

Mats Electronics has them for $99.00

remove your Lamp and look in middle of it,that will tell you if it is busted.

Hi,Yes your problem sounds like the DMD board.This is how it works: 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 : Have a blessed one!

Picture is scrambled after power surge. Have a

Check if it has a scrambled image on all sources ie - DVD- VCR - cable/satellite box. Since the PIP is normal it sounds like the signal source is bad.
Post back with more info about your set up (what's hooked to your TV) if you need more info

Replaced the color wheel on a Samsung DLP

Did you replace the color wheel yourself ? Sometimes you have to remove a small black jumper on the DM module on the light engine and that will remove the greenish but sometimes adjustments also need to be made in the service menu.

needs a DM Board, prity easy to change yourself, if you order one, make sure you give them the version number off the Right side of the TV, will be somthing like SP01, To change - when you take the back off the tv, it will be on the left hand side, have to unplug 3 or 4 connectors, then take the plastic covering off, and it will slide out.

Distorted image, lines, convergence?

If the pip is fine then the digital board is bad. Have it replaced by an authorized Samsung service center as the hex settings have to be copied from the dmd to the new digital board
