Question about Sharp Aquos LC65E77UM 65 in. LCD HDTV
This TV when plugged is DEAD! No standby light. The AC enters the power control board at 120 Volts and the fuses seem to be ok. None of the PINs have any DC voltage except for PP3 which reads around 2.0 to 2.5 VDC. I am assuming this is the standby voltage, which i believe should be 5 VDC. Am i correct in assuming this and if the standby is approximate 2.0 VDC I have a bad power supply board? Any help would be appreciated.
To get the accurate values to all the pins and test points, you have to download the repair manual to this set by internet. If you wish to get some details about the voltage charts, check the site linked here. http://electronicshelponline.blogspot.com/ Pull up previous posts there, either by its left side bar, or view it in Timeslide option.

SOURCE: have a 30" SHARP Aquos LC30HV2U that has a bad power supply. Nothing happens when I turn on the LCD - though it is getting power confirmed by green light going on but nothing on LCD. Visual inspection
You did try the CLEAR button on front of the box?
One possible idea is the cables going the box to the TV. ( might be bad )
If your sure about the problem, you can get your Service Manual here:
This with have all the schematic, diagrams, part number, and test points you need.
