OK, I'm back. Basically, if I start turning the two knobs, the four voltages keep changing, seems like from 0-4.77V. It's pretty jumpy though. So I guess, it's fine than. Before, I wasn't turning the knobs. HDMI cable, is connected now.

I'm taking a little brake, with this receiver. I'm repairing an Onkyo TX-NR626(Chk Speaker). I also have a Lenovo E520 to diagnose, I'm building a PC for the garage, that I'm using for repair jobs. I have to install a radar detector(Escort Redline), in my car(hard wire). Just a couple of days.

It's not connected. You are saying, that all my measuring can be off, because of this HDMI cable?

First, I will measure again those points. Just to be sure, that I have measured it properly. I have purchased new probes for my meter(Probe Masters), the ones I had previously, I could not trust them anymore. The tips, were sliding in and out way to easily.(TL910 used, from Ebay) I don't have the receiver in front of me, but I don't know exactly, which harness is for the selector.

It is bouncing up to 4.794V. Both of them.

OK, at the R3119 and R3122 at the common point is 4.803V and at the opposite ends, the same 0.001V for both.

R3114 (IC side)= 0.001V, other end= 4.813V R3117 (IC side)= 4.766V, other end= 4.813V(common with the above) The other two are not present on this side of the PCB. Did not have time to take the board off from the front. May not even be there on this model.

I have checked the board today and there are no transistors in those four spots. They are just marked, empty spots.

Sorry about not giving the measurements, but I'm (bad)sick.

I was adjusting the idle current on the Onkyo and I had to replace my 616 with this 636, plus I had to set it up. Today, I have measured all the required pins. I will scan and attach it here, tomorrow from work. It would be a lot of typing, to write all that again. Grounded all the shields and wires to the chassy.

I'm seeing two Pioneer VSX-1122k on Ebay right now, and one of them at least, has the same exact issue as mine(shows Power ON). It seems, like this is a common issue with this model. In the past, I have seen another one on Ebay, with the same exact issue.

The Onkyo, it's working! I have still found another bad transistor, at the final check(2SA1037). I have picked up a NTE2409, from Frys Electronics.

OK, now I have measured at all three pins 4.823V. I have grounded that metal shield to the chassy.

I have noticed some differences myself, when I have re-checked again. There are some metal shields, mounted to the chassy and by removing the front, these are not grounded. I'm wondering if the issue is not there. I will check them later on again and this time, I will connect a wire between the front and the chassy.
