Oh, I see. you replaced the .69 with the 15.66v. odd that the voltage is that much higher then 702 output.

703 is about 16 and 702 is about 12. Just rechecked

Ok, then we will assume for now that it is ok. Next, on that same board locate R766 and R767. Put your DMM on DC and test each resistor, 1 at a time with a probe on each side the resistor. We are looking for around 45 to 64 v.

They should be near D714 and D715 rectifiers.

I don't see those. I can see r765. But no 66 and 67

Ok, good. On that board locate connector CX115. Is there a wire harness coming off that connector and if yes, what kind?

Got it. It's connects to the left up rite board that was the ribbon cables to the front panel. 11 wires innit

It's a 11 wire connector. And it connects the main board to the side board that has the ribbon cables that go to front panel

Yes, 11 wires. Now I need you to locate the pin 8 wire. The board should be marked as to which is pin 1. When you are sure you have the pin 8 wire, leave some slack and then cut it. Leave enough slack to reconnect later.
Now assemble most of the unit, leaving those jumpers in place and see if the unit turns on. You probably still have to hit the power button but we need to see if it comes on or the led still blinks. DO NOT connect any speakers. The protection is partly disabled.

Ok 8th clipped. Am I completly reassembling everything?

Well I'm not sure. Some receivers dont need to be completely assembled and some dont like it if they are not. You can try it as you go along to see if it turns on at some point.

So I am all together except for board with transistors on top. 8u-110041-1. This has the one I cut on it. So the 3rd leg is cut but I'm showing a short on the board not the transistor. J803 and j802 are the traces
