hello, more info to consider, with current PSU of 700W after to short green and black and the fan starts to spin, noticed that one or two lamps of 70W were glowing!!, indicating a higher consumption.

Scratching my head about this, went to my storage and grabbed another PSU of smaller power, about 400W, connected it with the same fan, and one or two ligth were almost off, got the clamp meter and read 0.3A, so it seems that besides the short is gone, there is higher consumption so I seems that there is another component that...

ATX PSU Cooler Master RS-700-pcaa-e3 shutting off after 5 seconds
Got this from my kid with a fault on primary side. Main power supply here is AC 220V. All caps were Ok, testing with 2 series lamp of 70W each, got a bright lamp . Checked main heatsink one by one with my component tester and found one 3 leg buddy MDP18N50 that passed away. Got same replacement after a week, tested, short was gone, now I got 310V on primary.
Happy as a dog, added one case fan for some load and the fan of the PSU. Tested purple wire, got 5.1V, great!. Shorted green and black, fan spins and after about 5 seconds shuts down. I was able to measure doing several iterations...6 Photos

Re: Dell 2007FPB teardown
Hello, I am trying to repair this monitor that blown the 3A fuse...Just doing some testing on other components and thinking about this picture that found on the forum

Based on that the 12V are for the speakers, the 5V are for the USB, could be possible to just scrap the board and just replace it with a buck converter for the 3.3V, just to make it work as a monitor, no USB, no speakers...
Please let me know your thougths......
