The failure of the BIOS chip and the stuck CPU LED was very interesting.(Thank you)

14:58 to check eeprom data fixation, bad byts, for exemple.. in your eeprom writer fill all 00 and write and verify.. they all must be what you write 00. do the same but now using FF. some times have a error that is the same as the file i need to write, so the verification givew me ok, but that 0x00xx was bad. and you will not find.

Great job. I have always been flashing 1.8v bios chips with CH341A which is 3.3v. Never had any issues with it.

its not super risky just sometimes never verifies due to bad write small area similar to what he had but could be chip or center pad grounding a pin on wrong adapter not wson8 qfn8

CH341a data pins are current limited to something ridiculously low, i forget, something like 2mA, so the inherent pin drive resistance and the protection diodes end up eating the voltage difference. If you don't have a CPU connected that should be OK but it's not quite proper and i'm not sure i'm considering all the corner cases. Most CH341A boards are made supplying CH from 5V instead of 3V3 and it still works not killing every single 3V3 chip either. Ch341 is very very slow though so one wouldn't be using that given a choice, and other programmers have a different voltage-current behaviour.

I have the CH341A board, I haven't tried flashing a BIOS yet, where do you get the software program from? I see some of these BIOS boards come with a disk(software program). Can you direct me to a program I can use with this. Thanks.

I have this same motherboard. i was using my PC and suddenly it turned off. After that, there were no signs of power. changed the PSU still had no luck. The next day when I tried to test it again it turned on but the Mosfet near the two capacitors on IO side burnt and smoked.fortunately Processor was not in the socket:) Now pc runs fine but I'm worried that it might damage the processor. What do you think I should replace the damaged Mosfet?i watched so many videos of yours and learned a lot. I'm confident enough to replace the MOSFET if I have to do so🙃 waiting for your suggestion.

you got lucky w the QFN8 wson8 6x8mm chip.. the adapter pins sometimes touch center ground pad under chip and wont detect so try kapton tape under center ground... or get the yellow adapter for them cheap. also try asprogrammer but ch341a is not a pros tool.. try T48 or RT809F or even cheap xp866+

Lower end boards are most of the time not worth repairing money wise! For experience and knowledge they are great or sometimes for content, but money wise they are not!

I'm a bit uncomfortable with that hot air near these plastic connectors around the BIOS chip without any protection. Especially after i saw the melted connector on your programmer adapter. I suggest at least use some kapton tape to protect these connectors

A lot of repairs are around AMD chipset. Is it on purpose or AMD motherboards are more prone to fail?

Actually the chipsets or the PCH´s in my experience fail way more often on Intel Boards! Ive never had a B450 Chipset fail on me and ive worked on a lot of these, but for example X99 or Z270 Chipsets are dying left and right!
