TO test the power supply, use a meter tester and measure the voltages
between the different coloured wires on the power supply.

I had a similiar problem myself and found that it was a loose connection
where the power wires come out of the power supply. I ended up disconnecting
the power wires, twisting them round a few times and reconnecting them. This
tightened up the connection and the problem went away.

Subject: [xl7] MP7 won't light up


My worst nightmares have been brought to life! I was playing with my
MP7 and noticed that my siedlaczek orchestral rom was not being read
or recognized by the unit. Any preset i tried to use with samples
from this ROM appeared with '???'. I decided to re-seat the ROM, so i
turned off the unit, disconnected it, unscrewed it and put the card
back in, this time in slot 4 (it was in slot 3 originally). I screwed
the case back together and connected the power and tried to switch it
on but now i get nothing. I don't get ANY lights or screen, the unit
is totally non-functioning. I tried taking various ROMs out, moving
their slots, using different power cables, checking connection of the
grey cables in the box but i get nothing! I'm pretty sure re-seating
my siedlaczek ROM did not cause this problem... Perhaps I have blown
the power supply, busted one of the grey cables or bent a pin,
however i can see NO physical damage at all, not even a slightly bent
pin.

Anyone got any ideas how I can test the power supply and/or get my
unit working again? :(
