When I originally started with my DVR recorder it had 4 individual switching switching power supply’s that were sh*t so I bought a 7 amp 12 volt switching power supply and modified the output plug and put a four output power supply cable to match the input power supply cable inputs
Which worked for over 14 years until a few days ago when the cameras went dark no picture anymore well it turns out now the switching power supply has stopped working altogether now so I have to troubleshoot what has happened to this power supply more later on today what I found

Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".
It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...07-31-2025, 08:37 PM -
Hello guys,
I would like a quite old but still good 800 W ATX PSU to be repaired. The problem was an extremely heavy coil whine coming from the small secondary transfomer on the PCB.
I desoldered it hoping the references on the upper side would allow me to find a adequate replacement part. Sadly the written references drove me nowhere but to the manufacturer (I-MAG). I sent them a message like a bottle in the see asking them to send me a datasheet of the transformer. And... They responded ! I received a kind of datasheet (see attachment) but my competencies do not allow... -

Hello,
Not sure if this is the correct section, but I have a PS4 controller that I am trying to fix. It developed stick drift on the left stick and the usual simpler methods did not fix the problem.
So I went on eBay and ordered some replacement potentiometers. https://www.ebay.co.uk/itm/174967976757 is where I got them from.
I took the green potentiometers off the replacement sticks and soldered them onto the PCB. Assembled the controller and ran some tests. The drifting was somewhat fixed (not fully in center, but way better than before). However,...
