Picture Problem with Samsung UN40C7000

post #1 of 6
Thread Starter 
I apologize if I missed a thread dealing with this issue, but my TV occasionally has issues with the right half of the screen going red. If there is no picture (plain black), the right side will be solid red. If there is a picture on screen, the objects will have a red outline to them. When it happens again, I'll take a pic.

I originally thought the problem was with my PC, but the problem was present when I was using my PS3 (both hooked up with HDMI to my Onkyo TX-NR3008). Since I have everything going through my receiver, I thought that it might the problem. When I switched to channel 3 I saw that cable TV (coax) also had the issue. At this point, I think it's a TV problem.

Has anyone had this problem, and how was it fixed. Thanks.

So it happens even when it's not in 3D? Not good for sure.

Correct. I've actually never seen it while in 3D mode...then again, I'm almost always using it in 2D. I contacted Samsung, and they created a repair ticket for me. I'm waiting for it to happen again so I can send a pic to the repair company.

I was searching and saw that someone had a similar issue, and it was caused by an unstable voltage regulator (or something like that). The main difference is that only half of my screen is affected...so far.

I do think it is a display issue. Sucks that your having issues for sure.

The repair company sent over a tech, and he's guessing that the main board went bad. He couldn't reproduce the problem, so he just swapped the board. Since the problem only occurs once in a while, I guess I won't know if it was actually fixed unless it happens again. Here are a couple pics:

My TV is having the exact same issues like yours. So, by changing the mainboard, did that fix your problem?
