Hi.i m having a dead vd 1212 next to the heatsinks.can you please tell which is the negative side on this diode?the red or the white?i will replace it with 2 in series 1n4148.it manifests on shutting down the power .if i restart it 3 4 times or if i warmed it with hot air works very fine.i hope this will fix it
