My alpine MRV1507 won't power up at all, no lights..
I have inspected visually both circuit boards and they seem to be in good condition.
on bench test the caps charge, I have followed the 12v some what in to the main first board but until I know what i'm looking for I don't want to go any further.
I love old skool audio and I would love to get this baby working again, it is in very good condition.
Your help would be much appreciated
Thanks

Post the DC voltage on all legs of Q606 and Q607.
The amp needs to have power applied including remote voltage. Place the black meter probe on the screw for the main ground terminal on the amp. Don't let the probe slip and short between terminals.
