Re: LiteOn PA-6601-1A (600w) blows its TOP

Yes, it looks as if Q301 shorted, caused R302 to burn up, took out F1, caused damage to C301 and C302 due to their proximity to R302. Possible heat damage to the Schottky and the PNP Transistor. Q302 and C303 appear ok electrically (but I should've ordered C303). I will try to document the repair process with photos when the parts arrive.

Re: LiteOn PA-6601-1A (600w) blows its TOP

Nice to see this thread isn't completely dead. Listed below is my BOM (accumulated through this thread), which I intend to order from Digikey Canada.

Before I submit the order, does anyone see anything obviously out of place as far as these part numbers go? My TOP has no obvious visual damage and electrically doesn't suggest any signs of a short circuit. I will change the startup cap anyway.

All the other parts listed here have suffered visible or test-evident damage. I have had this PSU apart for months...
