This radio/cassette player essentially has no sound. It belongs to a friend and he tells me it has no sound/volume. It's on my bench and it has a 23 pin input which I assume I can fabricate a harness to power it up and troubleshoot. I've not found much info but assume when installed there is a remote wired controller on the handlebars. Anyone know of schematics for this monster or common problems concerning the volume control. I prefer not to tear into it with a multimeter without any direction, although I will if need be. Thanks, gary

I posted this tip elsewhere but the FixYa site is, shall we say, challenging.<br />
After years of use my Tivoli PAL started having volume problems. The audio began popping, volume changed erratically, static, booming, almost feedback sounds.<br />
In my case, and others as well, I've gleaned, the problem was the volume potentiometer. Apparently it oxidizes over time and the poor electrical contact is the reason for the erractic audio.<br />
I'm not an electrical repair kind of guy, so this isn't pretty.<br />
The volume and frequency controllers are secured to the knobs with metal collars. I pried the collars loose and got the horizontal board off, I sprayed Stabilant 22 into the volume pot. There are other electrical contact cleaners as well.<br />
Put it all back together. Let the flud dry. Good as new.<br />
That depends on the make and model of the radio, and the available inputs on the GHC1000. Does your radio have a line output socket? If not, you can generally use the headphone socket to source a signal. Then all you'll need is a cable with a 3.5mm stereo plug on one end and two x RCA plugs at the other - easily available at low cost from an electronics store. The RCA plugs go to a free line input on the Grundig amplifier and the 3.5 mm plug goes into the radio's headphone socket. HOWEVER some radios require a DC return path to detect that there is something plugged into the socket. You Grundig cannot provide this, and if your radio needs it, this method will not work. So hopefully your radio will not need it.....
By the way, you will have to experiment with the volume setting on the radio if you decide to try connecting it this way and find that it does work. Set too low there will be insufficient audio to run the Home Theater at reasonable volume, too high and you'll get distorted sound. Trial and error is the way to go, but start with the Grundig's volume control set to a low level and the radio's volume control set about half way - to protect your speakers from potential damage if you accidentally drive them too loud
This is an easy fix with a can of volume knob cleaner i think its called. You should be able to get it at radio shack. You just spray it into the volume knob and let it dry. The instructions are on the can.
how about the antenna this could be the main problem im not a motorcycle expert but radios i do know and if your getting static the antenna which is called the aireal << spell check is not picking up enough signal
