Thanks.
I'll try it in the TV tomorrow....Leave a comment:

Re: Philips 40PFH6510/88 not powering on
Look like replacing the 100V diode solved the issue, I see normal voltages on the DC side.
But my soldering sucks. I tried to apply generous amount of solder, but it's skewed.
Should I start again (not lazy but afraid of too much heat to the diode) or is it good enough?...Leave a comment:

Thanks - also for nomoresonys - I already learnt a lot...

It's a k11a65d, should be an N channel FET.
It's label on PCB is Q9301...Last edited by ph445; 10-25-2023, 06:25 AM.Leave a comment:

Maybe I should not test it in the PCB, but it doesn't look like a fet according to the tester.
It the diode replacement doesn't help I will solder this out and test it again....Leave a comment:

Hmm, this looks like shorted.
I order one and get back....Leave a comment:

Philips 40PFH6510/88 not powering on
Hello,
I have a Philips 40PFH6510/88 TV which is not switching on. No no standby led, no nothing. There was no bang, no smoke, it was simply switched off and next day it did not switch on.
I got the power PCB out and visually checked it, I did not see anything unusal on it, the fuse is OK and no cracked, burned components on either side, capacitors looks OK to me.
Both big 450V capacitors are charging up to around 330V but on the secondary side I can't get any reasonal voltage on any output pins. Most are around 0.2-0.3 V. (not sure which one is standby,... -
