I have a nice 386sx Epson "El Plus" PC I've grown up with since the late '90s, it has always worked perfectly, until I kinda "abandoned" for a few months last year and now, all of sudden, it powers on but I get no video.
It doesn't even beep, it just powers on, does all the floppy and HDD sounds, but I get no video on the monitor (a CRT 14-pin VGA monitor which works, because I also tested it on my 486 PC and the monitor works fine).
I thought it might be the CMOS batter, but I can't find any inside, I can't even find an RTC chip, here's a photo I took of the whole board.
I shall do whatever it takes to bring this PC back to life, it's the only PC I have that lets me play vintage '80s games without the "fast CPU" framerate problems.
