No audio.
replaced the output transistors and the ird20957s and a top side 100uf 16v cap exploded. c13
2 10r resistors burned up.

C13 is the filter cap for the +12VE supply for the Vcc pin 11 IC4-IRS20957. R142 & R143-10 ohm are in line with C13. R141 is a 2 ohm resistor.

Is it possible you have a solder bridge or the IRS20957 was installed backwards?Check C93-457/C and D31-ESD1

This is an unusual failure.

ok so ordered all parts that i will need on these repairs.
I thought i was doing something wrong, maybe pulling the incorrect resistor for the protection.
the red protection led stays lit.
but the 494 will produce drive.

C93 is a 4.7uF, not sure what the voltage rating is but the cap is on the 12v line for IC4-pin 11 of the IRS20957-VCC. Check IC4,C95. The 12v is coming from Q17-BCP56, ZD8-13v zener. C13-100uF 16v may have shorted.

so i replaced the capacitors that read a short with some from another unit for now. amplifier still is in protection with the resistor r68. The issue is i put new outputs in the amp and it was working came out of protection, had audio, until q19 shorts everytime? the resistors are all good?
