I have an LNT-4665F that had the notorious capacitor issue, which I was able to resolve very easily. However, I did let it go on with that issue for the better part of two years prior to taking action. Other than taking a little longer to power on, it wasn't an inconvenience so I didn't want to take a chance on possibly damaging it further by removing the board and changing the caps.

Unfortunately, I started experiencing a different issue. Once the set would power on, the left half of the screen would be very dark. If there was a very bright scene on TV at the time, we could see a little bit but on average or darker scenes, we pretty much couldn't see anything. Nothing seemed to make this situation better.
I wasn't sure if anything was related between the capacitor issue and the darkness issue, so I moved forward with the capacitor replacement. Once the repair was complete, the set powered on instantly (and still does) however the darkness issue persists. Except now, the whole screen is darker than it should be, with the left side seeming to be worse. Also, the refresh rate is TERRIBLE. When I'm navigating through the system menus, it takes a second or so for the next menu to appear on the screen, with the previous menu still "ghosted" in the background.

I took a really bad picture, but its the best I could produce with my iPhone. Please let me know if there is any hope in repairing this thing any further!

Thanks in advance!
