Hi
Just out of interest does anybody have a theory about what caused the original chain of events that caused the 15v power supply failure? The previous owner (did not appear technical at all) said they used it for a while until it started going into protection from time to time until it stopped completely.
C523 blew up when first plugged in caused by R535 failing. It came out of protection after replacing these. Why did the diode fail? The fuse at the back had also been replaced as well I noticed. The main circuit board had also been patched due to broken tracks.
Plugged in at wrong voltage perhaps or just aging components?
Thanks
