Plan C | HP Pavilion Slimline, Black Screen no P.O.S.T. Power Supply Fix @Plan-C | Uploaded June 2022 | Updated October 2024, 1 hour ago.
A neighbour's old desktop PC showed strange behaviour. More often than not, it would not start and just show a black screen. It would not POST.
I fixed it by changing a capacitor in the proprietary power supply. Not the most exciting repair but I thought I would document the process.
The PC is an old Pentium Dual Core HP Pavilion Slimline desktop S3714UK but the principle would hold true for newer machines as well.
Good Luck All
