I had the same board from a HD having a weird behavior, compressor will start no issues, run up to 3 days sometimes or just 3 minutes other times, screen will go blank, recycle power back to biz. All soldering was good, no cracks or open connections. The side smd led's will indicate all ok when it worked but when the issue happened one will go off. I did power test and some semiconductor tests at my bench, I did not find the issue (electrical and controls engineer here) O.S. will start ok most time, manufacturer recommended to replace the O.S. memory card due possible corruption, I had my doubts but owner agreed to try switching it, random issue continued. Owner sent the board to a well known and reputable board repair company, they sent it back labeled non repairable. Ended up getting a replacement board which comes with some adapters and removed a small comms. board, original board same as yours in video was not available and obsolete according to manufacturer. New board is electronically less complex and runs linux faster, compressor back to life. Note that when original board failed compressor was about 4 years old. We suspect power blackouts due lightning affected the board, even with the protections and filters high transient may affect this board. In the process I discovered manufacturer service manual for this board was wrong in the power connector specs, manual says 12 and 5 volts feed this board, but is only 12 volts, there is 5 and 3.3 volts regulators in the board. Great video!
Thanks Daniel Radio Shack I miss that place! Resistor Paradise! I'm heading back to Commercial side hopefully! Got company that invented T87F Thermostat looking at my resume! There sweet company to work for! Lol! Be safe! Lock out Tag Out Always! Always use a meter!

You have some great tools. Does your company provide the tools and/ or cost?
Is that the back of your van? I’d love to see a tour of that!
Yes. I am currently making a video of my van.
