Hi all, so I had a friend who gave me a bad TV that is using this Vestel PS, and the TV is stuck at stand by, will not power.
I took it a part and immediately saw a few bad capacitors, I replaced them all right away but no change.
I've checked my output voltages, and the problem is 12V and 24V are 0, so i basically only have 5V and 3.3V.
I've looked around in the forum for similar problems and checked everything I read that could be the issue but couldn't find anything.
I've looked for shorts around the PFC controller chip, nothing there that I could find.
All the diodes are ok, I couldn't find any shorts, so now I really don't know what else to check. To be honest I love electronics but unfortunately my troubleshooting skills need to be perfected and that's what I'm looking for, hope someone can help do just that.
Thank you.
