One more thing I noticed just now rechecking if the new FL was - or +, as the power is on longer and I re test those points the voltage there goes down. I went to FL first this time and it was .7 so I left the Probe there and it slowly went down to the .333.
Not sure if that means anything.

Minus? Are you sure your test leads were not backwards? lol Remove C406 and retest. Yep it is minus. test leads were correct just rechecked. Removing C406

Just remove those 2 and carefully test all outputs for any differences. This is where i want to see if there is a change. Where are you with this? Those are gone

Since the heat sink is already detached then it is probably easier at this point to just remove the remainders and then we can continue. But we will no longer be testing as you did once those outputs go back in. I have an alternate solution but we can get into that later. So quickly pull the rest of those outputs and lets see what you have on those output lines.Ok so the parts are gone from the other bad channel resistors and diodes. All amps are out as well. Still have DC 1.2 average Nashou

I keep forgetting you don't have the heatsink on there. I never test without one. Crap!!! Remember we had it off then you said for a quick check it was ok. I never had it on for more than a few minute's or so. Nashou

ok before I could get to the last 3 another Resistor popped and took out the SL Channel parts same as the others.
But before the pop, SR read 1.4 and SL read 1.3
Also the amps were very hot to the touch. the others were warm to hot.No heat sink......

Don't be trying to turn it on. More can be damaged. Just remove those 2 and carefully test all outputs for any differences. This is where i want to see if there is a change. Ok, Sorry I'll get as close to acurate reading as I can if it doesnt jump around. Nashou

Even that is to much. Is that on all of them? Yes and amp wont stay on if I try the reset. I'm on to R416 and R 419 Where are the equivalent FR resistors?
