The problem is that, it is turning on and off, draws large current without any load. All output FETs are ok, all diodes OK. On FET there is only 5.7V.
Capacitors looks ok. No burnt part visible also.
Any idea?
Thanks
It doesnot blow fuses, just power led blinks. I can see current draws more than 5 amps and then goes down. looks like, power supply side problem. no audio.
schematic would be helpful.
thanks
Are you using a power supply to try to power it up?
These amps are VERY sensitive to dips in voltage and will shut down if it drops too low. The dip in voltage that's too quick to be read with a multimeter can shut it down.
