Hey guys, I was about to attempt a repair of an old Yamaha digital piano however, it ended up getting damaged before I even began (my son was helping me set up this heavy beast and he accidentally screwed the wrong screw into the wrong hole.) Well, of course, the circuit board got damaged as apparently the keyboard didn't have anything to stop it from continuing straight through to the board. Luckily I got this thing for free, but it still sucks.
The piano originally worked perfectly, except that it would freeze/lockup after playing a few notes (usually after about 10 notes, sometimes a few more.) If you turned it off and on it would work again until you pressed another few keys. I figured that it was probably overheating due to a few bad capacitors in the power supply or amplifier, but I never even got a chance to even test them.
Anyways, can you guys please let me know if there is anything that could be done to possibly repair this board? I know it's pretty bad. The model is from 1989, so a replacement board is totally out of the question. I'm not very optimistic, but any ideas/hope would be appreciated I admit that I'm pretty green when it comes to electronics with no formal training, but I'm decent at soldering and have replaced a lot of caps in the past. I have a regular multimeter, but was waiting for an LCR to arrive from china. It looks like I might not have an immediate need anymore
Below are a few pics of the damage, the image with the black wire is from the back where the screw came up.
Thanks
