Guys!
I would like to share that one of my clients ask me that his Yamaha PSR-31 has no power. after thorough checking and asking for a solution and how to check this equipment I found out that certain capacitors and regulator TD880 are leaky and shorted.
Please see the attached picture.
just used the diode mode.
