Sharp 32" LCD tv, screen going blank every few minutes.

I have an LC32DG8E Sharp 32" LCD tv. The tv keeps going blank and scrolling through the AV channels on it's own as if it's loosing the signal from the SKY box. I've bought a new SCART lead and tried everthing :(

It turned out to be the HDMI cable of all things, tried hiding the remote and working my way back to basics. Once I disconnected the HDMI cable it worked perfectly, and bizarrely, even now I've plugged it back in it's still working!

TV screen goes blank but power stays on


Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.

The screen on our Sharp LC-26SD1E keeps going blank yet the sound continues. What is likely to be causing this?


This is the statistical order of the possible cause of an LCD screen going black:
The backplane lamps, and or the backplane power supply is also failing. Other caused can be from the main power supply, or the LCD panel matrix drivers, or the processor.

When you bring the TV in for service to the factory service rep, they will swap out the boards to zero in on the faulty board.

This type of set is mainly service by board swap, and factory re-alignment procedures when necessary.

Try new/different cable, if still have problem? You have a loose connection in the unit on the connector.
