You blew a diode near back of radio.(1) Take back cover off.spkr side) (2), see if you spot a black diode with a white stripe in right hand side between audio transformer and chassis near power wires coming in. (3)replace that diode; solder it..it may work again.

M-series gateway (m1629) press start button, nothing


Taken apart, looking for abnormal solder etc checked powers switches decided that this unit was acting like it may have shut down due to excessive heat issue. pulled battery on board, tested ok, re-installed everything and found that this unit now is active. Conclusion: I suspect the bios shut this unit down, hard reset correct this issue.

DVD Player does not turn on


Check the power connection on the player. Wiggle it to see if the ON lite blinks. Polaroid has had problems with this connections. ON lite will indicate that the fuse probably is OK. But there may not be complete power to the whole player because of a bad power connection.
