Anyone know what could be wrong? My Tv works, it turns on, and you can watch it, except for the fact that both the right and left sides have about a distinct 4 inch wide strip from top to bottom. In these areas there are black horizontal and vertical lines making boxes boardered with black lines and the picture is more blurry then the rest of the screen. The rest of the screen is blurry also and just doesnt look right. My good old regular tube tv looks better at this point. They came and looked at it, but couldnt give me a correct answer on what it was. They mentioned the board or the processor but they really didnt know the guy was an idiot...

Your light tunnel is likely collapsing. Very common on Samsung DLPs. Any tech who does much Samsung work should know about this. Post an image and I can likely confirm it visually.

I think I have to have a few more post before I can put up images because I am a new forum member I remember seeing that when I signed up....the tech said it was the dmd board or dlp chip but after doing a few hours of research I dont have those symptoms at all. Since the extended warranty is now over service isnt free so now I have to hassle with this myself. I did a lot of complaining and it got me no where....I have an engineering degree and I am pretty tech savy so I am confident I can fix this myself since I have also found the service manual. So if you can confirm this diagnosis it would be greatly appreciated so I can watch tv normally again. I have also found this problem online that looks similar and it was the light tunnel.

There is a post padding thread or you can just make a few more posts here to discuss the problem.

If you are patient, good with your hands and have a screwdriver you can likely fix it youself.

Im sure I can fix it I just want to make sure I know whats wrong without replacing part after part.Lol Yes I got a few good pics that show the areas on the left and right of the screen. It doesnt show how the screen is "blury" or the resolution is low. Hopefully the parts are cheap then I will be really lucky.

Actually, that could be a DMD board or a digital board. Is it the same on all types of inputs? Are the menus affected?

I cannot give you step by step instructions. It would require reviewing the service and training literature and evaluating the set. That kind of troubleshooting is beyond the scope of this forum and is usually impractical remotely.

Have you tried all types of signals and resolutions? That is the first thing that I would do. What about PIP?
