I have replaced those 4 component and the issue remains. so atleast i know i didnt make it worse
So ive removed the sealed up "S.M.S.L ultra low noise PSU". it has 2 pins coming in from the AC mains power and 3 pins coming out.
Can anyone help understand why there is only 2 in but 3 out.
I have opened up the sealed PSU unit and its a soft metal case (lead?) and inside its full of rubber solution that i had to pick around to see inside. i will get some pics soon. but i dont think this is something i can repair due to the rubber stuff all over everything. so.
As we know it generates 12v DC 1a im thinking of bypassing it and running an external PSU wires directly to the board but im stuck as to what the 3rd output would be.
EDIT:
Looking at the PCB traces i see "V+" "V-" and "PGND"
Where would i wire the ground to if i bypass the SMPS?
