I can definitely test those as well, but I wasn't getting any power at J513, so I think its on the ac/dc board.
I have the promedia 5.1 and it has had a low hum for a couple years.I just moved the subwoofer to the other side of my desk and away from my home stereo speakers and TV.Thinking it was getting some kind of interference.
But moving it made the problem worse.
Now as soon as I plug in the Sub and power on the controller the humming is so loud it is deafening.And this is without any speakers connected.
I ordered a new controller unit.But I still have the same problem.
Has anyone else had this problem ? And if so what do you recommend ?
I would like to get it fixed as the speakers work fine.And I now have two controllers.The old style and a new 5.1 ultra controler.
Sorry, I couldn't find some of those, so I was looking for the same label in other places. Doh.
Anyway, I'm not sure of the 2 next to R527. Closest to 527 gives:5020, and the next one over from it (nearest to the blue caps) gives: 5110 (R529 ?).
MR7 gives 100.5k.
Also, there is some very very faint scoring or black marks near the 3 resistors near J513... I think one of them is labled z5 something but I cannot tell. Starting with that one and working toward J513 gives:
I to had no sound from my klipsch 5.1s.
After about an hour of investigation and reading on the forums
R527 (4.7 ohm) ---
R529 (5110 ohm) ---
D5 and D6 (FR204) ---
All three 47uF
The sound worked great for about 15 minutes. Now the sound will play for 10 seconds then its sounds muffled or distorted for 15 seconds then it sounds fine. When I let the speakers sit for a few hours the audio works for about 5 minutes then it sounds muffled like before
I measured at J13
14.8 Pin 1
-20.4 Pin 3
-26.5 Pin 4
-32.9 Pin 5
Any insight on where to go to next would be greatly appreciated.
