SOURCE: LCD picture distortion.
This is caused by a failure of the main board. The failure causes the refresh rate of the unit to be off creating a trailing or ghost effect. This will require a technician to replace that board though. Hope this help.

SOURCE: TV screen went dark, but sound still there.
your backlight burnt out, this will be a maybe several hundred dollar repair. the screen is backilt by a very expensive flourescent light, without that light, the screen will be black.

You most definately have bad capacitors in the power supply. try and get it repaired as soon as possible, not an expensive repair that iv'e seen.

Sorry, this has no easy fix. The good news is you do not need an LCD Panel. The bad news is the Video Processor has a problem.
This TV has x3 Boards. The one you should replace first is the one in the middle. If this doesn't fix it, try the one on the right. The Part #s are on the Boards if you wanna try ebay.
