I also need the pictures.

well from what i understand theres a seperate 5 volts section on the mainboard that sends a voltage to the power supply that turns on a relay on the psu and then power supply outputs i may be wrong but budm im sure will confirm whilst your waiting maybe take some clear pictures of the mainboard connectors and any writing by them which tells us what the connector pins do it also maybe worth while in doing this for the power supply comnncetors too.

I need the numbers as printed on the barcode sticker, I cannot see it very well, 3104328????????.
You also need to check the SMD fuse on the bottom side of the board.

And for me but that section i gather is for the 5 volts that turns the power supply on so next step i guess is too see if its out putting 5 volts its just knowing where the test point is someone with more experience im sure will look at the schematic and advise you.

If i understand, the problem is in the mainboard, anD not in the power supply. Right?

maybe budm can advise what to check next im not sure too be honest as im still learning too.

I tryed to study the service Manual, but is very very difficult to me

With all unplugged i reading 0 ohm

Re: tv lcd Philips 42pfl9632d/10 Power board ko

yes thats the one test the ohms across it with the set uplugged and report your reading.

Re: tv lcd Philips 42pfl9632d/10 Power board ko

now i understand, do you mean the red SMD fuse on the main board. i think that is ok, but this afternoon i will retest again. i think that is good because on the cap after the fuse there are V

Re: tv lcd Philips 42pfl9632d/10 Power board ko

the fuse we mean is on the mainboard see my post 77

Re: tv lcd Philips 42pfl9632d/10 Power board ko

This SCH for SSB power supply may be closed enough.
So as you can see, no 5V no Voltage for the relay.

Re: tv lcd Philips 42pfl9632d/10 Power board ko

That is also the next move I was going to suggest, checking that main AC fuse.
BTW, he should download this service manual, it is not exact match but may be good enough to use as the guide:

Budm do you meen the fuse in the power supply? If is it, i just test it and tryed to replace

Thanks budm it proves i read and learn from yours and other techs posts. reading schematics is another matter thats going to take some time learning although the various training manuals ive read so far are very good and easily explained etc.

You will need to re assemble all the boards and connectors the on top right if the main board theres a oblong fuse by the black connector what dc volts do you get on each side of this fuse.

EIDIT or with your multi meter in ohms mode what does it read when you test across this fuse (you dont need to reconnect all boards etc back up this is just to test the fuse)

Here the photos of the mainboard

Re: tv lcd Philips 42pfl9632d/10 Power board ko

Top and bottom side of the main board so we can look at the small power supply on that main board? We need to get that 5V from the main board power supply.

as budm says once you get good clear pictures of the main board we can try too help you

Re: tv lcd Philips 42pfl9632d/10 Power board ko

Wondering if this gets measured in DC voltage and if its plugged in (just to be sure to confirm that there is not even a 160 dcv standby)

Yes Martino i tested it in DCV with power supply plugged to the current
