When power button us pressed.. I hear a click & front indicator light turns white but has no picture or backlight.

Any ideas?

try to post some pics., of your boards, I'd start with checking the fuse on the power supply board, careful power supply has high voltage.

Re: Phillips 42OFL3704D/F7

Thanks for the replies. I attached a picture & hope it tells you a idea what may be wrong.

Re: Phillips 42OFL3704D/F7

I thought I better post clearer pictures.

Re: Phillips 42OFL3704D/F7

Did the pictures give any ideas what the issue may be? Thanks

Do you have a digital multi-meter?

There doesn't look to be much info on this set. If your power supply has labels at the connectors for the expected voltage, I would prove each pin at each connector to look for that expected voltage. Personally, I suspect your main board, without knowing what the expected voltages on each pin are, I can't really help you with any guidance.

Please upload the pictures of the whole back side of the TV so I can see all the boards.
Check to see if you do have 24Vdc on any one of the red wires (black probe on the chassis) on the white connectors which should go to the inverter board.

try to grab a manual, if the power supply board isn't labeled with expected voltages where connectors go, if the voltages are correct, then power supply is prob. good.

my phillips had blown capacitors on inverter board.

BTW, is the TV actually is 42PFL3704D/F7, not Phillips 42OFL3704D/F7.

Re: Phillips 42OFL3704D/F7

Did anyone ever figure out what this issue was? I have the same TV with the same problem.

I checked all the voltage going from the inverter board to other boards, all seem to be correct.

Re: Phillips 42OFL3704D/F7

To elaborate a bit more, when I plug in the TV or turn it on, after about 7 seconds there is a brief flicker on the front of the TV then it all goes dark.
