Amp will not power up its dead I have 0 volts on all pins of the 594 any suggestions?

Follow the trace back from pin 12. IT likely goes to a Q901. Post the voltage on all 3 legs of Q901 (or whatever transistor it goes to).

 

[S Merlington]

It goes to Q902

I have 0 volts on all 3 legs

Are you sure that the fuse isn't blown?

 

[S Merlington]

Both fuses looked fine but i replaced them and the amp powers up perfectly Thanks for the info

 

[S Merlington]

Amp worked for about a week and came back to me and it wont power up again..

I replaced both fuse's with new and the amp still wont power up..

I have 0 0.00 volts on all 3 legs of Q902

I also have 00.00 volts on all pins of the 594

Did you pull the board to look for bad solder connections or burned traces?

 

[S Merlington]

Yes do see any.. I will heat up the solder and see if that does anything
