Mine is a MPS3003-L
It seems the Matrix version of OP’s PSU is MPS-3010l-1.
sorry my bad,its a 10a linear,when i got ot only one pair of pass transistors were getting drive,4 power diodes were open also 4 4007 diodes open,i replaced those and now i get 0 output,theres is a 555 controling a relay that shouls latch,seems thats dead,its like the output wont turn on,it did output power with the 2 pass transistors not beeing driven but was 5a max.
Slowly, please. Both from your attempted repair and how you write I get a feeling of doing everything extremely hastily. To me it’s almost impossible to even understand, what you want to say. The photos don’t show much.
Do not rush, do not randomly replace elements. Eight diodes being short sounds weird. I am not saying it’s impossible, but it would be very rare and indicate some major catastrophic failure. Whatever caused the diodes to release magic smoke is still there and will likely kill new ones too. The culprit should be identified. You did not mention the fuse too. If there was a short, no to mention a short of magnitude sufficient to instantly nuke eight elements, and fuse would not act, you would be holding a molten blob of plastic.
Work step by step. Try to understand the overall construction of the PSU and then ensure, without powering it on, there is no unintended shorts. Take photos of the inside: but please do it with proper light, possibly from a desk lamp. If your camera can’t focus, try from bigger distance. We can deal with poorer resolution, but not with blurred, overexposed images.
