Hello all, this receiver goes into protect mode after i try and turn it on; i have the service manual and it states there are 2 types of "protect modes", one were the word appears on the display and one were it doesn't. In my case i see nothing on the display, i hit the power button, i can hear a relay click and then it goes into protect mode. I have checked the output resistors and transistors and found no short. I have tried to measure voltages and seem to be only getting a 5VDC reading but not the 12VDC, that is coming out of the power supply even before it gets to the voltage regulators. Does anyone have any ideas about what else i can check? Thank you.
