Re: Philips 22PFL3505D/F7 no power
Number 4 looks bad, try set the meter to 200 Ohms scale and see if it still showing low Ohm reading.
This #4 power supply is one of the 5v power supply that gets regulated down to 3.3V by the regulator circuits.Last edited by budm; 12-12-2012, 12:39 AM.Never stop learning

Non stock, you may have to contact them to see what else they have, you can go for higher voltage and current in DO-15 case style.
Original spec is 50V, 1.5A, 150nS Recovery time, Vf 1.2V, DO-15. Just tell them you are looking for FR151 sub.Never stop learning

Hi all!
I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅
I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!
I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy... -

Hello everyone. I'm brand new to the group. I'm trying to fix this Philips 4K TV. I have minimal experience with most of this so forgive me if I don't understand half of what is posted on these forums. I'm trying to find my way through it.
Basically I got the TV from a previous owner who said it just died on them. So I wasn't there when it broke. It will not power on, no lights, no backlight, no sound.
The output of the power supply has a 27 pin connection to the main board. Pins 18-27 (labeled P-On+20v) are the only pins reading power at 12v each. The pins marked ALL+3.3v, which...
