Hi I could do with some help on this on.
The tv turns on with sound but no picture/screen does not flash just blank.
All the voltages are there i.e vs 205 va 55.
I have checked the buffers they seem fine- tested them with a multimeter and took one out and turned the tv on - but no half picture.
On the ysus there is no vy voltage and there is no voltage going to the buffers.
On the ysus the mosfets are not shorted. The 5 transistors on the rear seem fine (30f132 ). Nothing is short to chasis.
Ive detached the main board ribbon to tcon and put a jumper auto gen but no test patterns.
Repeated it but this time with zsus detached still no test patterns.
The led on the tcon hasnt flashed in any of the tests.
Can it be the panel or is it the actual tcon board?
Any help would be really appreciated
