Question about Toshiba 42H81 42" Rear Projection Television

1 Answer

Toshiba 42h81 With the main screen on, there are horizontal lines from top to bottom and shaking occurs. However, when you use split screen, the screen on the right is fine and the one on the left is as the main screen. Could it be that the main tuner is out??

Toshiba 42H81 - Screen flicker

Since the problem initially would correct itself, it suggests a poor connection somewhere that "heat" would resolve. If you can solder, try resoldering any joints that appear to be grainy or have rings. Please note that these sets will retain high voltages that can be dangerous even when unplugged. If the resoldering fails to resolve the problem, let us know and we'll look further.

Hello, one of possible solutions is to replace capacitors (10uF/50V) on HYPER (PD0246) module. Please ask the tech to check/replace them. If you need more info please advice.
