Re: Phillips 42OFL3704D/F7
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.Comment

Re: Phillips 42OFL3704D/F7
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.Comment

Re: Phillips 42OFL3704D/F7
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.

Re: Phillips 42OFL3704D/F7
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.Comment

Re: Phillips 42OFL3704D/F7
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.Comment

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.Comment

Hello.
My TV is a QE65Q800TATXXC Samsung TV.
Issue : When you plug the 220V, voltages are OK on the power board and you can hear the click from the relay, but TV is not starting when power button is pressed. Red led is blinking when you press power button. But no images or sound ( Back-light is off )
Then if you disconnect the cable from the main board to the power supply, the TV back-light turns on.
Any ideas to check would be very appreciated 😊

Hi.
Some weeks ago, my beloved 10 years old PC went belly up
When I press the power button, the video card cooler start spinning, but I hear no POST beep and I see no image on the screen.
The CPU gets mildly warm, but it might overheat if let running more than a few minutes without radiator, so I let the radiator on it (no fan).
There is no chip overheating - I "fingered" all of them
, I looked also through a cheap thermal camera.
Not a single LED lights up.

I measured the power on all pins. It is all... -
Hello. I bought a faulty Lenovo ideapad 3, but it turns out the 3Valw buck converter burnt a hole through the board. I was able to clean it up, and remove all the shorts. I now can power the 3.3v rails from a bench power suppy while connecting the laptop to its psu, and I get the additional 5valw, 1.8v, and 1.05v, form what I can tell in the schematics, those are the only 4 voltages I should see before turning on, and they are present. When I hit the power button, the power indicator on the left side turns on (not the one on the power button), stays on for about 12 seconds, then turns off for... -

Hello.
I received a bios locked 7410 with 25Q256JVEQ ,i dump the bios, unlocked it and flash it back, since then the laptop has no life signs at all except amber led on for as long the power button is pressed, nothing else.
Fact #1 i was unaware that 25Q256JVEQ is 3.3v and i used a 5v CH341A to program it, not sure if the chip got damaged but since then i can read it and write it normally, doesn't seem dead.
Fact #2 i modded the CH341A to 3.3v, same results with programming though, nothing changed.
Fact #3 i tried hard reset with cmos/main battery disconnected and power...
