Hi all,

I was recently repairing my SA-HT70 dvd player because the subwoofer kept
cutting out. I fixed the problem. Then, I was about to remove a little
piece
of plastic that had fallen onto the circuit board with my tweezers. I
accidently dropped the tweezers onto the circuit board - this caused a big
spark with some smoke. Now, when plugged in, the unit displays the red
stand-
by light, but when I press the power button, it goes green for about 2
seconds then back into standby (red), whilst the relay near the power
input
clicks once or twice. Does anybody know what that means and if I can fix
it?
Thanks.


Check for +28v on pin 14 of IC502. If missing, safety resistor FP549 is
open. Failing that, you've probably fried IC502. I've got the relevant part
of the schematic as a pdf if you need it. Contact me off group with a valid
e-mail if you do.
