    Faulty HT820V receiver sends 4 to 5 Hz signal to woofer electronics causing its relay to chatter and receiver does not work. If cable to woofer is disconnected receiver appears to work OK (but without sound). How do I fix receiver fault? What parts can I transplant from a 2nd receiver stuck on VHS? Thank you in advance for your help.

    No, the relay chatter is a symptom of a problem IN receiver #1. A fault in receiver #1 causes relay chatter in electronics in woofer box AND its CD,FM,VHS do not work. (All 5 speaker amps are in woofer box.) W/o 20 wire cable connected from receiver to electronics in woofer box CD, FM,VHS in Receiver #1 appear to work OK but of course no sound. 2nd identical receiver #2 is stuck on VHS and its CD, FM, VHS don't work. But no relay chatter when receiver #2 connected to amps in woofer boxes 1 or 2 and amps in the 2 boxes do work OK. Question: What fault in Receiver #1 is causing relay chatter and CD/FM/VHS malfunction? OR, how can I get receiver #2 unstuck from VHS and its CD, FM and VHS to work?

    Both receivers are identical models but have different problems. Please my problem description above. I would like to get either receiver to work.

    Ok, so your problem is the relay from your woofer ? and you only have a subwoofer hooked up to it ?

    Make sure the woofer is not getting too much bass, this might account for the chatter. and check if your woofer is hooked into the right output. Do you have any other speakers that do not make strange noises when they are hooked up ?

    Hope that helped a bit.

    Reply if you need more assistance.

    So you have both receivers hooked up and the panasonic one is hooked up to the woofer and is causing the chatter and the malfunction of CD/FM/VHS ?

    What kind is your other receiver ?

    I would first of all check all your wiring and make sure it is fully intact.

    If you want to see if the problem is in your receiver or your speakers/wires try hooking up headphones and see if they get sound, if they do the problem is within your receiver.

How to charge battery

I think it recharges by taking some power from the computer when it is connected. I also use a cell phone charger from the razor series of phone.
