Question about Audio & Video Receivers
This receiver powers up and then shuts off within 2 seconds. The outputs are all good and there is no DC present in the output stage. The bias on the base of the power relay driver is being removed by the micro and I dont know why. The protection circuit does not appear to be activated in any way. The speaker protect relay does not have a chance to engage because the amp does not stay powered long enough.
Any assistance with this would be greatly appreciated.
This unit is in the protection mode. See the link below. If you have further questions, please post them here.
