I have a Sharp Aquos Quattron.
LC-52LE830U. One side of the screen is fine, but for some reason the left has a darker picture. Still have an image, just darker than the other side. And a noticeable vertical strip in the middle that is kinda grainy. I was able to enter Service mode, and got error code 21. Looked it up, code is panel power failure. Any ideas?

Either half of the backlight has failed or the T-Con board or possibly the LCD panel itself has failed.

It could also just be caused by a loose ribbon cable connector from the T-Con or main board to the display panel.

How old is the TV? Is it still under warranty?

Do you plan on carrying out the repairs yourself?

A repair by a technician is likely to cost around $200 if it is not serious.

If the panel is faulty then the TV is beyond economical repair.

TV is a few years old. I opened up the case, but did not find any loose cables, but I only checked the board that has the inputs. Not sure which board is the T-con. I can replace parts, I just don't know what any of them are called, lol. can the T-con or main board be replaced? If so, how do I find a replacement? How do I make sure I can the right stuff? Or should I just have a repair guy do it? I can replace them, just not sure what to order.

Here is a useful video that shows the boards and cables inside a typical Sharp Aquos TV - you can watch from 4:20 onwards, after the cover is removed:
