Hi friends,
I recently acquired an old PC power supply (along with several vintage motherboards from late 90s/early 2000s). The PSU was dead upon first test, but quickly identified the internal fuse had blown. I fixed that, re-tested and i'm pleased to report it seemed to work great after that - no obvious issues or reasons for the fuse to blow.
Afterwards, I inspected the capacitors more closely and noticed one pair required replacement. They weren't in bad shape by any stretch of imagination, but one was slightly bulged, and I wanted to swap them out for good measure....

Hello, I am asking for help. After connecting the power supply, the TV will first blink once and then after a few seconds it will blink 4 times. All voltages on the motherboard are OK, but when there is a cyclical one blink the voltages 3.3V, 0.9V, 1.5V, 12V on the L80 coil also reset. So this x1 blink is like Reset_SYS and then it's x4 blink. Where to look for the problem? There is no Service Manual, I rule out the problem of bios on IC401 because I have already done it. I found descriptions of SOS on the Internet and 4 x blink is Power SOS P Board Help. Regards12-02-2023, 11:57 AM

This laptop came in for no power. I saw the board was not taking any power so I pulled the board and began testing. As you see in the photo, on those pair of mosfets, I had 20v into and out of mosfet 1 and 20v into mosfet 2, but only 3v out of mosfet 2. I found a location which was shorted and injected 1v5a and it took all the current, but nothing is heating up with the thermal camera and I can't for the life of me figure out how 5a isn't showing on thermal.Yesterday, 08:51 AM

I have a MacBook Pro A1502 with no power.
180-200mA without battery, 1500mA with battery, and orange light on the charger.
Short facts:
*USB with LED lights up.
*No fan spin.
*Adapter sense and sys_onewire is ”only” 2.861V.
I checked the DC board as well and the adapter sense is 2.861 V, I'm not sure if it's too low
That's why I'm asking you guys for help.

Recently acquired one of those silly Logisys acrylic power supplies and lucked into getting one of the "better" ones (most of an input filter, bridge rectifier instead of 4 diode treatment, OK-sized heatsinks, etc.) and wanted to fill out what I can on the board + get some decent caps on there (especially the primary side since I highly doubt the ones in there are actually 1000uf). My questions are:
1. How do I know what components to install re: the input filter? It seem to be missing an X cap, a resistor, and a Y cap.
2. Where can I find a good heatsink for the bridge...Yesterday, 09:59 AM

Hi friends,
I recently acquired an old PC power supply (along with several vintage motherboards from late 90s/early 2000s). The PSU was dead upon first test, but quickly identified the internal fuse had blown. I fixed that, re-tested and i'm pleased to report it seemed to work great after that - no obvious issues or reasons for the fuse to blow.
Afterwards, I inspected the capacitors more closely and noticed one pair required replacement. They weren't in bad shape by any stretch of imagination, but one was slightly bulged, and I wanted to swap them out for good measure....Yesterday, 04:35 PM -

Bosch WDU28560GB/02 washer-dryer. After selecting the spin program, the clock jumps from 0:13 immediately to 0:05 and counts down the minutes to zero. The pump turns on and the door locks, but nothing else happens, the drum doesn't spin. After the countdown ends, it does not open the door, it can only be opened by pulling the emergency handle next to the filter. No error is shown. When I select spinning and hold my finger in the lower left corner of the screen, after 5 seconds E60 and -09 are shown alternately. What could be the problem? Is it possible to turn on the service mode so that the washer-dryer...12-04-2023, 04:01 PM
