LCD panel failure symptoms

Hello all:

We have a 32 inch Samsung LCD television what I believe is exhibiting the symptoms of pending panel failure.

While watching the Masters yesterday, we noticed some shadowing around the screen mostly confined to one side of the LCD panel. This shadowing was present regardless of programming viewed.

How does an LCD panel fail when nearing the end of its life?

Symptoms will vary depending on the type of panel and type of failure. Part of the panel going dark or lines are quite common. In general, if it doesn't look like it should then it's failing. Modern panels typically cannot be repaired. Complete failure could indicate a problem with the power supply. That should be easy to fix but often isn't worth it due to the cost of repairs vs value of the TV or replacement cost.

Sometimes the connections at the top/bottom of the panel go bad, but if this were the case you probably wouldn't be able to see anything in those areas. This can sometimes be temporarily "fixed" by running your finger with some pressure across the top or bottom of the screen itself. This would be similar to unplugging/replugging a poor cable connection to get rid of oxidation (which may also be your problem?)

I agree with @ExDilbert , especially for a 32" TV - not worth fixing with a new TV available for less than the cost of a repair (unless you do it yourself)
