Re: one channel only
Try the following:
Swap the RCAs at the input. If the dead channel follows the RCA signal, check the signal source and cabling.
Move all controls and switches to see if the dead channel makes any noise. If so, a dirty switch may be causing the problem.
If neither of those help, you may have a blown power supply for the dead channel. Look at the 3 legged devices clamped to the heatsink. Do you see any that show signs of damage or have black soot near them?

Bad ground sounds like you may have paint or undercoating stopping the ground from making good contact or unhook the remote wire and run a small wire from the main power to the remote hook up and see if it works ...... May have a faulty remote
Remove all the wires from the amp including the remote turn on wire. Once you do that, after about 30 seconds the amp will reset. Hook the power up first, then the ground then the remote. Turn the unit on and check for power WITHOUT the speakers hooked up. If you get no power by now it's a good chance that the amp is cooked. If you do get power, try hoking up your speakers first on one channel then the other channel and then bridged. If it cuts out or off when you touch the speaker wires to one channel or the other, then that channel is no good. Hope this helps.
YOUR METHOD OF TROUBLESHOOTING USING THE PROCESS OF ELIMINATION IS RIGHT ON AND PERFECT. IT INDICATES A BAD AMPLIFIER CHANNEL. I KNOW THIS SOUNDS ODD, AS YOU HAVE TWO OF THESE NOW. IT IS RARE, BUT I HAVE SEEN INPUT CONFIGURATION SWITCHES WIRED BACKWARDS, SO THE ONLY THING LEFT TO DO IS TO HOOK UP THE BAD CHANNEL TO ONE SPEAKER ONLY, BY ITSELF. THEN TAKE ONE RCA ONLY AND PLUG IT INTO ONE RCA INPUT AT A TIME. THEN MOVE THE INPUT SWITCHES AND REPEAT THIS PROCEDURE UNTIL YOU HAVE TRIED ALL SWITCH COMBINATIONS AND ALL INPUT JACKS. WHAT YOU ARE TRYING TO DO AT THIS POINT IS TO DETERMINE IF THERE IS ANY RCA JACK WITH ANY SWITCH POSITION, THAT WILL ALLOW YOU TO GET OUTPUT FROM THAT CHANNEL. IF AFTER THIS TEST, YOU STILL HAVE NO OUTPUT, THEN NO MATTER HOW ODD, IT WOULD INDICATE THAT YOU DO IN FACT HAVE A SECOND DEFECTIVE AMPLIFIER. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE.....V
if its cutting off and right back on then check your ground and your power wire makes sure both are connected good and none of your fuse's are blown, either that or you got a wire hooked up backwards in the sub.. but my guess is that the sub is hooked up wrong... that sub should be hooked up in a series or in parallel,
ok if your running just one speaker, it should be hooked up like this and 2 speakers are a different way...
this is parallel :pos to pos , neg to neg, then one wire coming from pos on sub to pos on amp then neg on sub to neg on amp but bridge the amp on your amp should be 2 pos and 2 neg in two different channels take the pos off the sub into the pos on 1 channel and then the neg from sub to the neg on the other channel,
this is series : on the sub it will go pos to neg then the other neg and pos will go to the amp, but make sure the pos and neg r on different sides of the sub, dont hook them both to the same coil
if your need more help give me your email and ill send you a pic of how to do it...
The power supply appears fried and possibly one or more of your output
channels. Unless you are good at repairing this sort of thing
then I would suggest you save your self a lot of hair getting pulled
out in frustation and go to a repair guy and let him pull his hair out
instead. Good luck.
How do you have the wires hooked from the sony reciever to the inputs on the mtx?
Sounds like your Remote wire is way too big. it should be 14 guage. It only sends a low voltage low amp signal.
Another thing that could be messing up the sounds is the routing of the wires. you should have the power supply wires separate from the Audiop signal wiring. Power should run down the Driver side and Audio down the passenger side.
