Re: Pioneer VSX-1120k non working preouts
While it comes on and appears to work it only puts out sound from analog sources in pure direct mode. Any ideas?

Re: Pioneer VSX-1120k non working preouts
Thanks for the non help...
Holding down the tune- button and the multizone on/off button simultaneously for 2 secs reset the unit and now it appears to function again. I have not tested the preouts yet....but at least it now turns on and off and has a normal display.Leave a comment:

Re: Pioneer VSX-1120k non working preouts
Looked over the preamp board and saw nothing unusual....Put it back together
And the minute it sees power the MACC light starts blinking......Please help someone
I have DMM and know how to use it....I cant afford to spend $400 to replace this unit.Leave a comment:

Re: Pioneer VSX-1120k non working preouts
Attached are a few pics: the 1st shows 2 of the cables going to the amp section. The white ribbon in the center. Just to the left of it under the grey cable , there's a diagonal plug from the transformer for power.
The 2nd shows the HDMI top board plugged in. The top board on the left side is the one that goes to the amp board and is the AWX connector.
The 3rd shows the Amp ribbon cable and the back of the PCB connector boards.
The 4th is the AWX connector board before the other boards were reinsta...Last edited by HemiRick; 03-21-2016, 10:11 PM.Leave a comment:

Re: Pioneer VSX-1120k non working preouts
Took it apart again....Amp board only has 3 connections 2 of them I didnt touch, the one I did is a PCB connector with plugs on either end; its labeled the AWX connector. The end I unplugged, plugs into the HDMI board. I inspected its pins and they are a straight and fine. The other 2 connections to the amp board I didnt touch are a ribbon cable and the power cable from the transfoprmer. The ribbon cable goes to the audio board. The optical in board and connector/Audio board below it were only flipped forward so I could access the RCA connectors...Leave a comment:

Re: Pioneer VSX-1120k non working preouts
I have not been able to find a service man for this exact amp. I one for 1020K and 1121K...The 1121K is closest. No ocilliscope...
I didn't touch the amp board....I just removed the top HDMI board and the back panel and then flipped the 2 boards under the HDMI forward.Leave a comment:

Re: KLIPSCH KSW-10 amplifier
The 1st diode measures good and the 2nd is bad. I know that much....but thats all I can contribute.Leave a comment:

Re: Pioneer VSX-1120k non working preouts
Put it back together and know I get a blinking MACC error and the display says Amp err I know this means DC on the speaker outputs....How I did most likely screw up putting it back together to cause this? The only things connected on the back are some HDMI connections and the Front preouts and of course the power cord. I took the rear panel off and the HDMI board loose from the hard connectors and flipped it forward, out of the way. Then the 2 boards below the HDMI board stayd together as I was able to get to the RCA connections at this...Last edited by HemiRick; 03-16-2016, 11:40 PM.Leave a comment:

Re: Pioneer VSX-1120k non working preouts
My quick initial tests indicate that the RCA preout connectors connect to the PCB just fine.....maybe this some weird software issue requiring a reset. I'll do some more brief test reassemble and reset.Leave a comment:

Re: Pioneer VSX-1120k non working preouts
By tweaked too hard I mean physically pulled or pushed on, I've read they mechanically break somehow.
Because the software does not even have the ability to turn off/on the front preouts, to my knowledge......yes I agree it does control the SW output.....Leave a comment:

Re: Pioneer VSX-1120k non working preouts

Re: Pioneer VSX-1120k non working preouts
Nope not kidding, have read on other forums where the subwoofer preouts fail on these if tweaked too hard, at least 4 instances. The amp works 100% fine except these 2 preouts are dead. This is not something software related, I'm very sure. Why would the Front L preout work and not the Front R?
I've found a manual to 1121k, much more similar model, almost identical.
I've gotten the top digital/computer board out and am working lower.....to the preouts.
The actual diagnosis and fix should be easy once I get there....Last edited by HemiRick; 03-13-2016, 10:22 PM.Leave a comment:

Pioneer VSX-1120k non working preouts
Hello everyone,
I have a Pioneer VSX-1120K that the subwoofer and and the Front R preout right next to it do not work, no signal. The amp itself otherwise works fine. I'm trying to take it apart to find and repair the bad connections to the preouts....But this thing is complicated. I need some help taking it apart. I need a manual that actually matches. I've found a manual for a vsx-60 which is very similar, but it has ribbon cables where mine has PCB's for connectors to the main HDMI board on the top. Any advice on getting the HDMI board out to get to the preouts? And the required... -
