Re: Suggestions Needed - dead MP4

2016-06-28 by jw_dewdney@yahoo.com

wow - it was actually very lucky in a way that I shorted one of the transistors in the power supply by mistake... IF i hadn't done that - i wouldn't have removed the KLM376A boatd and discovered that CN35 had cracked and LOOSE solder joints! ALSO - the entire board was CAKED with melted heat sink compound and sticky as hell - i had to bathe it all in alcohol to clean it all off... after i got that done I reflowed most of the solder joints and replaced most of the caps (had a few showing efllurorescence - or 'electrolyte leakage' - so not a bad idea. It turns out I didn't kill any transistors after all.... but rather the fuses (which of course i did not check - it would be too obvious!). Thanks much for your help everyone

Anyway - so the udpate now is I have a FULLY functioning MONO POLY (except for the keys which I will do next I guess)

I have some KaiCote 44... the synthhacker site suggests maybe it's not the best stuff to use (?) any comments on that?
