I think I might try replacing the LED driver board - looks like an inexpensive thing to try and if it doesn't help I'm only out 20 or 30 bucks.
Well, I found a used one on eBay for $13 and ordered it. When it arrived, it was not the same board as pictured. I would have tried it anyway, but one of the ports that accepts a cable was broken off. The seller refunded my money instantly. Found another one on eBay (also $13) and ordered that, it arrived yesterday and I installed it. So far, so good - I was able to turn the brightness up past 3 and it didn't go black. I'm working from home next week so if it doesn't black out again I'll consider the issue solved. Wish I had done it sooner!
