Mtx tna251 flashing red light

[Aaron waldrop]

I just acquired a older MTX tna251 and when it is powered up the red logo light just flashes no output. I pulled the back off all the mosfets look to be okay none burn but the output to the speaker has got hot and started to melt the plastic insulator around the terminal. Also in between two of the capacitors there is a resistor that has burned out but the numbers on the border gone to know what to replace it with any help would be appreciated and possibly a nice board schematic if that's possible thanks

Did you use a multimeter to see if any of the components clamped to the heatsink were shorted?
