Hello!
I resurrect this topic to ask if original poster (or anyone else) managed to fix the rework station.
Mine suddenly stopped displaying in solder iron display and it would not go hot. Hot air display operates as before as well as the air gun.
Zener diode D5 was shorted but replacing it with a PH C5V1 to no avail. Now there is a voltage drop of 0.7V.
I tested all the marked path in the photo above with continuity and they are ok. I cannot find anything else shorted or burnt. All resistors measure within specifications.
Any ideas? Can it be the heating element...

Thanks a lot for your reply.
In order to respond in the right way can you please inform which is the Super I/O chip in my case?
Thanks in advanceLeave a comment:

Re: Gigabyte GA-MA69G-S3H no post
I noticed that near the 6 K3919 mosfets there is a [URL="https://datasheetspdf.com/pdf-file/1305864/Renesas/ISL6312/1"]ISL6312[/URL] chip that is described as a "Four-Phase Buck PWM Controller with Integrated MOSFET Drivers for Intel VR10, VR11, and AMD Applications".
Can this be the culprit for the absence of Vcore? Watching [URL="https://www.youtube.com/watch?v=H05jfVUP1PA"]this video[/URL] and of what I can understand, this can be the case.
Any thoughts?Re: Gigabyte GA-MA69G-S3H...Leave a comment:

Re: Gigabyte GA-MA69G-S3H no post
Taking again a look at my measurements there seems to be no Vcore around the mobo. The only voltage near Vcore is on the WQ16 mosfet (40T03GH) below NorthBridge.
Shouldn't have I measured Vcore on the 6 K3919 above socket? AN if so why there is no voltage there?Leave a comment:

Hi!
Thanks for the reply.
The chip is a [url=https://datasheetspdf.com/pdf-file/672813/MacronixInternational/MX25L4005A/1]MX25L4005A[/url] and I get voltages as following:
3.8V 1 CS# Chip Select
3.3V 2 SO Serial Data Output
3.3V 3 WP# Write Protection
0.0V 4 GND Ground
3.3V 5 VCC + 3.3V Power Supply
60mV 6 HOLD# Hold, to pause the device without deselecting the device
3.3V 7 SCLK Clock Input
3.3V 8 SI Serial Data InputRe: Gigabyte GA-MA69G-S3H no post

I forgot to mention that nothing gets hot on the motherboard no matter how long it is powered on.Leave a comment:

Greetings to everyone.
This is my first post in the forum but I have consulted it many time in the past. I am getting into the hobby and I need all the help I can get.
To the point now. An AM2 motherboard was given to me that it was supposedly misflashed. The actual model is [URL="https://www.gigabyte.com/Motherboard/GA-MA69G-S3H-rev-10"]Gigabyte GA-MA69G-S3H[/URL]. Having a CH341 programmer I managed to flash a copy of the latest bios on Gigabyte's site but when I tested it with the existing Athlon 64 x2 5200+ that had onboard didn't manage to get it to...Last edited by Tankard; 02-15-2022, 04:22 PM. -
