Yay! Was able to repair one PSU by replacing a bad 18N60M2. Was thrown off by the 1.5V diode reading bc my Fluke reads Pin 8 at 0.816V on a known good.
HI, Could you help me identify a couple of components on the FR board please? one is a vener marked VM V1 (ZD39) and another is a diode marked GS5MB (D1) if you have mnuafactures codes that would be so helpful. I have had two supplies blow the R100 resistor (R96) as well as one of these diodes which i havent seen you come across yet
ZD39 should be marked ZM. It is a PDZ18B from NXP. GS5MB looks to be a general purpose 1000V, 5A diode. www.jjwdz.com/pdf/zhengliu/GS5AB~GS5MB%E4%BA%A7%E5%93%81%E8%A7%84%E6%A0%BC%E4%B9%A6.pdf
Do you repair ps5 from viewers? I have one with a 400FR supply that was dead i replaced the power supply now it just beeps? I'll keep watching you are the best!
No, I don't believe so. This supplies shutdown very quickly when they detect any kind of problem. I don't believe it will send out gate pulses endlessly without seeing voltage from the feedback circuit.
