Question about Audio Players & Recorders
Hi i have got a goodmans hec142 dvd with seperate 5.1 surround amp, i switched it on and only the right hand side sound is working, I disconnected the speakers one by one and managed to get the sub to work as well but after 10 seconds it cuts out and protects it self. I then have to disconnect the amp pcb for it to power back up. is there any test procedure for the amp pcb that i can do with a multi meter? to determine the fault? Thanks in advance.
The amp pcb is a
Mustek pcb, amp board,A920r / a820r
SOURCE: Right side speakers don't work
if you are using RCAs as inputs to your amp.Swap the R to L @ RCAs to see if its comming in okay from radio.If both RCAs have audio then amp is bad ,If amp has any type of switches , move swithces to see if it comes back .Also if both RCAs inputs have audio .Move the RCAs when connected on amp to see if amp has bad connection in board to RCA jacks..If audio comes back on bad side when jack is moves .Then you have bad solder joints on board..If not then you must have bad outputs on amp..

What model do you have?
You should be able to plug the audio/video output from the satellite TV system into the audio/video input on the JVC system. Then set the JVC system to the appropriate input.
I need to know the exact model to know how or if this is even possible. Some JVC models don't let you input any additional devices. Others might not have the inputs that are necessary for surround.

I have an Infinity amp as well, and I was having the same issue for a time. The amp is protecting itself from some sort of overload. It could be the Ohms load on the sub, but I would guess not. Make sure your low pass filter is set to LP and not HP or Flat. Then check the RMS on your subs and match that to the Amp RMS. Once I did all that I found that everything worked fine, for a time. It started doing this again, and I checked the fuse and it was blown badly. It seems that the fuse setup on some of these Infinity amps is not as good as one would hope, because the charge was bridging the gap and frying out my fuses. It was like a spark would jump from one side of the fuse to the other without travelling the fuse itself, and this was causing my protect issues. I pulled the fuse, got a new one of the same rating, but I placed the fuse in with a little piece of rubber in between the 2 contacts, and then connected to the fuse block. I have not had problems since.
