Default Pioneer CDX-P1280 CD changer

Will not eject cartridge, acts like it is getting no power but power is
present at Plug. All microswitches check out. Any ideas?

Thanks in advance

noone:
AC power may be getting to the plug but you will have to dig deeper to
verify that the power supply is getting step down AC from the power
transformer and that the internal power supply is putting out DC voltages.
If the display is not lighting up then don't waste your time checking
microswitches.... troubleshoot the power supply.

Sorry for not being clear. The P1280 is a car cd changer. The 12V supply
is good, power OK at the board.
