I havent checked with the audio drive board. Now with the drive board inside, it goes always in protect, and no gate drive. If i leave the remote connected, it stays in protect and switch to on for half a second, than back to protect. I think there is also a issue with the audio board. I dont now which drivers are mounted, because they removed all markings.
Have you tried unplugging the two Driver ICs (probably IR2113s) from the audio board?
This may not be safe if there are no pulldown resistors for the outputs so be careful if you try it. If you read less than about 100k from the gate to source of the outputs with the driver ICs removed, it probably has pulldown resistors.

Continue. Received the new parts. Installed the new Voltage regulator. Tryed to start without the IR... Directly a resistor start smoking. This resistor is a 8Ohm, in line from the output of the Regulator. Goes to the IR Pin 3 on the board. Passing a Zener. Removed the Zener and checked with diode test. from each side 095 measured. So i think its broken. Any sugestion wich value this zener has?
