Philips 32PFL4505D/F7 No power

[sfernandes]

Hello,

As the title says I have no power dead set condition. Not even a standby LED.

I tested the fuse on the power supply at it was blown, so I replaced it with the same type and spec and as soon as I hit the power button on the set it blew again.

Any ideas what to check?

I have attached a picture of the power supply board.

Check for shorted Mosfets or Diodes. If is shorted and you put a new fuse in, it can still blow it.

Take the resistance reading between the two legs of the main filter cap, 470uf 220V to see if it shows very low resistance, you will have the meter connected to the legs of the cap for about a minute.
No power to the unit when making resistance reading.
