CEDAR AMD MB 13283-1 PWB XY1KC
It has MEC 1404-NU Super IO (or EC/KBC/Multicontroller) and as far as i know is a non programmable one. Since it powered on one time, its less likely a bad SIO. More likely the heat you applied when soldering and de-soldering the BIOS chip might have an effect on a nearby component which is failing and the board powered on temporarily. This is just a hypothesis but applying heat to different areas and you may get a clue. It's an old technique in Electronics troubleshooting.

Mounting and Handling Guidelines for TO220 TO220F TO247 Cases / Packages
The TO220, TO220F and TO247 are the popular packages for power devices because of their versatility and ability to dissipate moderate amounts of heat. This application note describes the basic guidelines for handling power MOSFETs in TO220, TO220 and TO247 packages shown in Figure 1. Please note that only mechanical and soldering guidelines are covered here. Additional precautions are required for isolating high voltage rated devices to meet safety regulations.

detecting heat with IR LED receiver
I have some dark IR led, and want to know if it is be situable to detect pure heat (not visable glow ir radiation) in well lighted desk?
So, if I put hand over it in near distance like few centimeters, that detect rising heat, not covering it from light.
Something like termal camera, but in one spot, any simple circuit?... -
Hello,
Purchased a broken Samsung UN39EH5003FXZA (Version CD01) to have fun fixing. When I first acquired it, I did not connect any video signals and only plugged it into the wall. The unit booted and showed the “no signal” window and I could navigate all menus and change sources. I unplugged it, connected my over-the-air antenna to the coax, powered it on, got the unit to scan the HDTV channels, and I think then the TV self-shutdown with the melody. When I powered back up (melody), it would show the channel selected on the OSD and after a couple of seconds, it self-shutdown... -
Hello everyone,
i was reballing the power manger of a moto g84, after applying heat i tried to power on and it wouldn’t.
i injected 1.5v to some capacitor that seem in short because both side beep if tested.
when i inject i feel the cpu burning;
since the cpu is exactly on the other side of the board, is that possible that the heat from the reballing damaged the cpu? do you know where i can find schematics or what can i do?
i know this is not enough to explain the situation so if you need any other info ask me please!
Thank you very much in advance11-08-2024, 02:13 PM -
Yesterday I successfully repaired a Middle Atlantic UPS2200R-IP that had inadvertently been used as a surge suppressor at our transmitter site. It has already been replaced with an updated one but it's coming home with me now instead of being e-cycled. To be specific, this is the MA model that has the blue backlit display and has been discontinued, although this design may have been used in many UPS units including the smaller Middle Atlantic ones in this series.
Here's what happened: We experienced a brownout/surge at the site, which damaged the UPS and took our broadcasting...
