Sharp Aquos 65" LCD: LC65D64U DEAD no power

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. Pull up previous posts there, either by its left side bar, or view it in Timeslide option.

    Unfortunately, the repair manual does not have the voltage chart.

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.

Samsung tv un60j6200afxza version ns02. No standby light and will not power on. Power board tested ok by tv tech. Replaced main board and still not working. Yes board tested ok. Tried multiple outlets to...

Power board is where 120 volts AC enters the TV. From the rear, the power board is on your right hand side (not bottom). After 120 volts, there is a fuse on the power line. Then the 120 volts go to a high voltage transformer and then there is a capacitor - 100 uf at 450 volts DC. Check the voltage here -- should be at least 390 volts or higher. If not, replace this capacitor with a higher capacity, ie, 350 uf with a rating of at least 400 volts (or any combination of capacitors totaling 350 uf.)

Sharp aquos won't turn on

Any indicator lights on, if it is then you only have the standby 5v circuit working, you will need to have the power supply check out first, that is a starting point.
