Spontaneous regeneration of an electronic component.
For the last week I’ve been getting my morning and evening voltage reading by poking the back of the display with a multimeter. Last night when I did it, I noticed a strange blue glow.
Silly thing magically decided to work again. My brother already sent me a new display for the box. Guess I’ll have a spare.
hmmmm. I have an intrinsic distrust of ‘self healing’ systems.
It’s a miracle!
Based on this week’s data, have you noticed any difference in your morning readings since you changed inverters?
No, not really…
Something tells me that if you were to look on the back of the panel, the name of the manufacturer would be… Skynet.
It’s been hacked . . . and is now transmitting your every action to THEM . . .

MJR, that could possibly explain that ominous music I heard all night long…
One day I was troubleshooting an intermittent problem on a computer memory board that the company sold for around $50,000. The standard way was by running the voltage of the power supplies up and down (within reason); there were 3 supplies, +12v, +5v and -5v. So I had my meter on one of them (say +12) while I turned the screw on that supply, and watched the oscilloscope for a failing waveform. Kept going back and forth doing this, then at one point I was turning the screw but noticed no change in the meter. Like an idiot I kept turning more and more and nothing happened. Then it dawned on me that I was turning the screw on the -5v supply while monitoring +12, and shut the computer down immediately. Pulled the board, checked the voltages again, the -5 was WAY off (coarse voltage adjust), set it right, put the board back in and ran the diagnostic. Now instead of having one bit failing intermittently, almost the entire board was failing. Oof. I sat there feeling sorry for myself, having destroyed such an expensive board… then after a while I ran it again, noticed somewhat less failure happening. Waited some more, still fewer failures. After a few hours I was back to one intermittent failing bit again.
I was more careful after that. 🙂
Paul: I did field service for 20 years. You ain’t the only one to have done something like that… (shudders at memory, decides to drink lunch)
OTOH, I was happy when tech supp said “Well, when you find out what’s causing it, let us know because we have no idea” and I had an answer. Made me feel like a real tech.
We’re having intermittent electric problems after having some significant electrical work on our house here in town. Hard to track down intermittent stuff so I don’t envy the electrician coming back out the first of next week. Meanwhile we’re running the whole house off of extension cords plugged into the 3 outlets that never were affected.
I heard that there’s a solar plasma cloud heading this way, so maybe our respective weird happenings are actually something coming out of thin air. 😉
I was an avionics tech in the Navy & a civilian electronics tech. We always said electronics was all FM–fuckin’ magic. Even knowing the theory down to electron level (which isn’t hard), The Electric do strange shit sometimes.
classic cold solder joint problem, reflow the suspected component leads and it should come back
