Samsung 46 inch LCD tv problem

When you turn the TV on, it works fine for almost 5 minutes, then the right 1/4 side of the screen goes dark and nearly black. Then a few minutes later, it comes back to normal with the exception of a faint/fuzzy little black S shaped line at the bottom right that is almost unnoticeable. Other than that, it works fine for the rest of the evening. Mike said he'd turn it on in the morning and leave it on all day and after the initial black out, it was OK.

Hi, Depeending on the thickness of the lines matters. If the lines are Black and about 1-2 inches thick it may be a bad bottom buffer board or a bad panel (screen).
If the lines are thin 1/16 to 1/8 inch it is most likely a bad panel.
You can open up the set and depending on the model, see the thin board/boards running across the bottom with ribbon cables going to the panel. You may be able to attempt reseating the ribbon cables, but be careful as some retainer plugs break very easy.
If the lines are thick black and the reseating doesn't correct it you may be able to buy the coresponding buffer. Unfortunately some bottom buffers are actually part of the panel. If you are not comfortable taking it apart then call a professional but be aware labor charges start around $200 not counting parts, panels start at $600 up to over $1000
hope this helps
Thanks
Eric

I just fixed this very same problem. It is the capacitors are the problem. However, I think that if you have some minimal skills with soldering, you can fix this yourself. You just need to take out the system board, then the power supply parts are on the top right. The bad capacitor(s) will be bulging at the top and possibly have some brown stuff coming out. The ones that go bad are 1000microfarad, 10V, however you can replace them with higher voltage. I got 35V caps from radio shack for 1.59 each. You just need to solder out the bad ones and then put the new ones in and solder. Remember that the negative end goes on the side with the bold black part of the circle on the system board. Then just cut off the extra ends of the capacitors. If you are capable of doing this yourself, you will spend at most 6 dollars instead of however much a technician costs.

Can this be fixed ? what is the problem?


What your describing sounds very much like a video board issue some part is not working properly until it warms up. Eventually it will most likely need to be replaced, If you are not sure what board or part is bad, in the long run it might be a better idea to just replace the TV.

Bad news, the LCD panel in your tv is going bad, call Samsung and complain about the problem, it is a manufacturing defect. It would cost more than a new TV to replace the "panel" or LCD screen. Good luck.

The problem is most likely in the image processor area, or the backplane circuitry on the screen itself.
The service rep would be equipped to properly service your set. You should call LG to find out who in your area is able to service your set.
If the set is out of warranty it could be fairly expensive to service.

This model of SONY TV uses a Samsung display panel, the problem you have is the panel went bad.

SONY was offering an extended warranty to change the panel free, please call SONY to check it out that if they still offer the free replacement.
