Casiotone mt-86

[Droeee]

Hi guys. I bent a casiotone mt-86 and things gone wrong. I replaced an IC and now it doesn't turn on. I "accidentally" connected two poles of a transistor (c + e) and it came back to life for a short moment. Btw there's another transistor that is getting HOT. I replaced every transitor I mentioned and the thing is still dead.
Any words of advice?
