Re: Philips 55PUS6262/12 always ON but no picture
Anyone have a clue to how to start troubleshooting the main board then? Is it "usually" a simple component that gives up, or is it more likely that it's a chip or something that you can't really check as a novice?

Alright, that explains why I am missing the 3,5V, but then I don't have aclue to why the TV doesn't work.
Or does it mean that the power supply is likely ok and that the main board is the culprit here?Leave a comment:

I don't know if it helps, but when the TV is on, two green LED's on the main board comes on and stays on the whole time. I don't know if they should, if they should blink or if there should be more of them....Last edited by tandkramstub; 09-01-2020, 03:06 AM.Leave a comment:

No problem, here's a picture of the whole PS and a close-up of the back of the terminal, the 3,5V is on the two pins just above the text "CN9101"....Leave a comment:

Right, I've finally been able to measure a bit more and taken some pictures as well.
I've focused on the black connector on the PS board which goes directly to the main board.
The results are like this:
Left row:
On/Off: 3,25V
NC: 2,95V
GND: has contact with chassis
GND: has contact with chassis
+12V_A: 12,0V
+12V: 12,0V
+12V: 12,0V
+3,5V: 0V
Right row:
DIM: 2,4V
PS_ON: 3,0V
GND: has contact with chassis
GND: has...Leave a comment:

Philips 55PUS6262/12 always ON but no picture
Hello!
So I was given a broken LED-TV with some unusual issues.
When I plug it in, it turns on and stays on, and does not respond at all.
The red standby light never comes on, it just switches on the backlight LED's and just stays that way.
The mainboard has a couple of green LED's that comes on and stays on, and I can't visually see any swollen or burnt components anywhere.
I replaced the T-con board to no awail and now I have started measuring voltages, but electronics on this level is above my knowledge.
The only clue I have is when... -
