Hello everybody,
I am new to the blog, so if I do not conform to the requests, please excuse me..
My problem is intermittent on Sharp mod: LC-52D65U. The TV will work OK for a period of time (different), than the screen go black, with sound. When you turn the TV OFF and ON, it comes back OK again, than after some time the screen goes black and so on and so on...
The unit is not so “young” and I can't get any information (service manual, trouble shooting, etc.). This is what I observed:
On the inverter board DAC-60T012 Master (see picture), the nine (9) pin connector has the following voltage, when I HAVE and do NOT HAVE picture:
Picture: Pin Voltage No Picture: Pin Voltage
2 3.3V 2 3.3V
5 3.0V 5 0.0V
8 2.84V 8 2.84V
Pin 5 has an “ERR” designation.
The second connector (three pin, not in the picture) coming from the power supply board has the following stable voltages in both “Picture” and “No Picture” states: pin 1: 60.7V; pin 2: Ground; Pin 3: 11.94V, all stable.
The unit is not so “young” and It seems, I can't find any service/trouble shooting manuals/schematics...
Any help is appreciated.
Thanks Nick
