Re: phillips 15pf5120/28
Did you replace all the caps that were the same as the bad ones? You may be able to find a replacement power supply if you Google around. Search Youtube for switching power supply repair guides: http://www.youtube.com/watch?v=TxGgUiUo1F4Comment

Re: phillips 15pf5120/28
Take pics of the boards using the manage attachments option and make sure they are of high quality. We need to check the voltages going out the power supply to make sure there are no other problems.
Also check any fuses that could be on the main/TCON/ or inverter.Comment

I do have several old pc motherboards which i recapped 10 year ago and some of those caps are bulged now.
I would like to upgrade them using solid capacitors. I do use them for testing and helping some alternative operating systems.
I would like to ask if such an upgrade can be done, what should i have in mind when replacing electrolytic by solid caps and if such thing exist, if there are caps list for old motherboards. I would have to figure out what caps needs each motherboard and then prepare a list to try to ask for them on some electronics stores. -
Hello everyone,
Mark and model: ASUS X571
Symptoms: not turning on. There is only the LED battery indicator working. The owner of the laptop told me this problem arrived one week after having changed the battery. He then managed to power on the laptop only once, and then it never powered on again.
Tests already made:
- Battery is charging when laptop is plugged in. The LED battery indicator turns white after a couple of hours of charge, indicating that battery is fully charged. However, laptop won't turn on anyway, with or without AC plug.

Hi friends
I have a dell XPS 9530 which had some liquid damage to the usb area. I replaced both the usbc iCs and not I can see 20v on the meter. But it does nothing and the 20v is not passing to charge the battery or turning on the board either.
I suspected the PD controller (usbc controller) but it will need to be flashed if I decide to replace it. I thought that if the usbc controller needs flashing then at least the board should turn on on the battery. I charged the battery externally and attached it to the laptop. Now the 11.8v is actually passed to the board I can... -

I have a Sony Bravia KDL-40V2500 that will not power on. The indicator flashes red 3 times.
I do not hear any sound and I cannot see any backlight.
I have tried disconnecting every cable on each board one at a time to see if anything changes.
The only change is when I disconnect AC-DET cable on the Power Supply board or on the other end if I unplug the CN7009 connection on the B-Board and try to power on the TV the indicator will stay on solid green until I power off.
My friend ordered another used power supply board but it is also doing the red indicator flash 3 times...
