Re: Sharp LC60LE660U screen flashes on power on then nothing

Does the lack of response mean that there is nothing else that can be done with this TV? If so, I guess she'll be good for the Ecocentre?

From reading other threads I think it is in locked up mode...

Re: Sharp LC60LE660U screen flashes on power on then nothing

Have I been abandoned? Don't really know what to try next. I did put the panel back together and laid it on face downwards ready to check voltages.

Re: Sharp LC60LE660U screen flashes on power on then nothing

Budwich: Will be getting on that later tonight.

Vinceroger69: That's an idea, and I tried it but no change. I tried it twice. Could it be another key combination on this model? Tks!

Re: Vizio E500i-A0, LED lamp beads, new sticky?

Re: Sharp LC60LE660U screen flashes on power on then nothing

Re: Sharp LC60LE660U screen flashes on power on then nothing
