Hello,
I've decided to start trying to fix some electronics for consumer items, just because I'm quite interested and I want to further my knowledge and skills in PCB level repair:
I've currently got a PC Monitor that does not turn on. I have its Power Supply PCB dismounted and on my desk.
The transformer that seperates both sides (H and L Voltage) sides of the PCB has all 4 pins shorted together at the top end and reads approx 85VAC against Earth and Neg. The +19v pins for the red wires (going off to the VGA board) has 80-90VAC there.
With this information what could I consider to try? Or what would anyone here think the issue could be? I've looked for this transformer online to check if these 4 pins should be shorted together but I can not find it for the life of me.
Thanks for your time.
Ryan
