Hello everyone
I recently got a PS5 EDM-020 board, no beep or light. I replaced a broken fuse and some caps that seems to be shorted, still no beep or light. How should I do for further diagnosis?
F7001 F7002, F7003, F7502 : 5.1 V, (F7003 is the fuse I replaced)
F7501, F5401, F3501: 11.9 V
F5401, F3502: 0 V (USB switch next to F3502 also 0 V)
Mag. module: pin1, 2, 3 1.6 V;
pin4, 5, 6 0.64 V;
pin7, 8, 9 2.09V;
pin10, 11, 12 0.65V;
others 0V
serial flash memory next to south bridge: pin1, 2, 3, 7 3.3 V, others 0V
PWR button: pin1 3.3V, pin2 2.9V (counting from the left), buttons work fine (voltage drops to 0 when pressed)
HDMI: pin7 from left 3.1V
PWR draw from lab Bench PSU: ~240 mA @ 12V, weird thing is that it doesn't drop to lower current for standby mode, ~ 240 mA all the time
