Not sure if anyone can help me here, but considering I don’t have many other options apart from a replacement motherboard at this point I thought I’d try anyway!
I was replacing the capacitors on my Duo 280c and there was a lot more goop than I realised. I thought I cleaned it all up (before my experiments with the LED backlight) and had some modern electrolytics instead (and seriously, the old ones were very bad.
Anyway today I got a sizzling noise and smoke, which is always fun. I’ve tidied the area as much as I can, I’ve discovered a shorted diode which I’ll replace (and for now is removed, I’m not going to power it on for a little while(!)) but I still have a dead short across C2 and C7.
Is someone else able to verify that this isn’t normal (and I totally imagine it could be when there isn’t any power, but it still seems kinda unlikely) or better yet I’d love a photo like the one below but without the…mess
