Sharp LC-52D64U no picture

[Mikeyjohnson]

Hey guy im trying to fix my 52" lcd tv. Everytime i turn it on only the power light stays solid green. No opc light nothing. When you hit the power button all you hear is a clickng noise that comes from what sound like the power supply. Exchanged the small power supply and larger one. Still having the same issue. Any ideas?

Most likely, is an inverter issue.

Need good clear straight on pictures of back of tv with cover off and each board.

Need voltages from connector that goes from power supply board to main board. Will need pin#- PIN DESCRIPTION -Pin voltage in standby-Pin voltage when pushing power button and picture of connector on power supply board.
Format:

1 - XXXXXXX - XXv - XXXv
2 - XXXXXXX - XXXv - XXXv
3 - XXXXXXX - XXXv - XXXv
4 - etc.
