I checked all the speaker terminals, the relays are all closed so they all read, the FR and FL both read positive 19 volts, so do the FL FR speaker B terminals (Both were on so I left it the way it was)
The Center SR and SL both read about 2.0mv positive so they appear to be fine.

okay I'm back, I did steps 1 through 3 and the transistors both checked out in and out of circuit, the diode D1052 checked good in circuit and is now MIA somewhere in the room (it flew off the board unfortunately). The receiver reassembled now stays on and the 2nd relay clicks, so what's next? Also D1052, do you know what the part # is so I could order a new one? I haven't given up yet on finding it, but I don't think I will...

Checked pins 1 and 2 on CN1051 again, same exact readings as before on those pins.

Okay, got it all back together, powered it on, it still does the same thing, displays POWER OFF, then goes back into standby, that's with both the D1055 and R1107 removed.

D1055 removed successfully and reads okay as well! Ill put it together and give the results.

Got the 100K R1107 SMD removed in 100% working condition still! Quite proud because its pretty microscopic!! Soldering it in will be easier than removing it was. Ill re-assemble the amp back into the unit ad power it up again and let you know the results

Found R1107, its on the bottom of the board, as is D1055, Ill remove the 1107 from the board first and see what it does

What board should I be looking on for R1107 and D1055? I don't think the amplifier board has any through hole diodes on it, only SMD ones on the bottom. It does have through hole resistors on it though.

okay mt, on CN1051 Pin 1 (DC) In standby when the receiver is plugged in it reads +4.65v, when powering it up it drops down to .8mv so basically nothing, Pin 2 (OL) Reads half a .5mv in standby, powered up it reads -14.5v. When powered back off Pin 1 goes back to 4.65v in standby, and Pin 2 goes back to .5mv

Hey MT, sorry it took a while to get back to you. The connector is actually on a board that connects directly to the amp board so its direct, no ribbon cable. I should be able to manage it safely

The amplifier blocks on this model are the collector of the amp itself so they have a charge on them while on, I can probably rig some tool to assist me in testing. The connection is pretty open but I have about 2 inches of space between both heat sink blocks. In other words, I am able and willing
