If the high side is shorting out but you still have 12v on the low, I would suspect a shorted PWM IC, since that is really the only thing that would be linking the high side to low side and would explain the blown rectifier. I often find that isolating the fault on a PSU can be one hell of a rabbit hole. A lot of replacing components, test, something else blows, etc. My advice would be to buy a replacement unless this is purely for practice or learning. -
If the BQ was what was getting hot, why did you not try replacing that? Or is that what you meant in your post when you said you swapped out the "BC"?Leave a comment:

It's as easy as this my man. You are making things way too hard on yourself. Nintendo has a service for bypassing parental locks. Cost $2 the last time i used it.

695 vs 686 is likely within tolerance. I wouldn't worry about it. What are the diode readings of all 19 pins on the port? Also I'm assuming you checked all your pins on the port and IC and made sure you had solid solder joints on everything else and no shorts anywhere.I have no knowledge of clock signals on HDMIs neither but In my years doing this, I have not needed to, to fix HDMI ports on any devices. Also check the EMC filters just below the port. If all else fails and you still are unable to find the fault, either the ic and/or port you used are duds or the apu is shot.
Hope this...Leave a comment:

I suggest getting the metal cover off the board and inspecting the connector itself for damage. These aslo get extremely dirty and it may just be dust. Also inspect the 5v rail for a short or fuses on the board (typically labeled Fxxx). Hope this helps....Leave a comment:

It sounds like the PSU might be ok and it's going into protection mode due to a fault on the motherboard itself. Have you tried looking at the board itself yet?Leave a comment:

Typically I will not repair a PSU in these side they are so inexpensive to replace. However, if you are intent on fixing it, I suggest looking at the pwm ICs and any of the 3-legged fets and mainline high voltage caps. Your fault is likely on the low side. I've never seen a short on the high side in any psu before. If your still unable to find the short, I suggest using a thermal cam....Leave a comment:

As far as the supercaps themselves, you do not need to replace them on the 1.6 versions of the boards. If your looking to put something in there that's going to last a long time, I just scrapping the idea of using a call at all and instead install rechargeable lithium button batteries. The Sega CD model 1 used then and I have yet to open one up where they needed replaced and they're over 30 years old.
Use aluminum caps, not wet.
Hope this helps....Leave a comment:

Are you sure they haven't just been replaced?...Leave a comment:

GV-N2060OC-6GD REV 2.0 GIGABYTE video card troubleshooting assistance needed.
The issue with this video card is the HDMI port. Specifically on pin 19 (Diode checks on all other pins are normal). When i do a diode check on it from the pin on the board itself, I have nothing. There is also no short on the pin. Resistance reads about 200k. Normally on any HDMI pin 19 I would expect some voltage drop anywhere from .5v to 1.2v but here, I have nothing. The card is operational and can be used via the displayPort ports, but not through the HDMI. Attached you will find the pdf schematics for the card on page 22. I have verified that all of the resistors on this line before the... -
