Question about Yamaha GX-500B Shelf System

Open Question

Memory loss Hi, I have a problem with my Yamaha GX-500CD shelf system. (Not sure if this is the same as GX-500B) It's a great system, but in all the time I've had it, the briefest interruption in mains power wipes all the station memories. I had got to the point where I no longer bothered using the radio section (we live in an area prone to regular power outages) as it's an absolute shocker to reprogram. The other day, I noticed an item in the manual to say that it's supposed to hold its memories for a week! And given that it's actually quite a nice tuner, I've decided I'd like to try using it again. Now, I'm a radio tech and Ham radio operator, and I have the service manual, but at 60, my knowledge is a little (ok, a lot) out of date, and I cannot see HOW it's supposed to hold the memories. I can't find a battery or supercap anywhere, and would have expected non-volatile ram to hold the memories forever. Can you help, or tell me what to look for...? I have not, at this stage, opened up the unit. Thanks, Michael

Looks like your wife damaged the tray. I should have a look, it might be something you can fix with a bit of superglue. It's worth a try!

CD changer won't open. Mechanical Error on display

There is a small hole just above the door on most CD changers. Unwind a small paper clip and GENTLY push it into the hole. This should release the door, and let you look inside. Don't force it because you could damage it more than it is already.

The cassette player door on my Yamaha GX-500 system doesn't open fully. The motor is working, but the door only moves one-half inch. Possible/expensive to fix?

Hi. I suspect that the belt may be worn and/or the motor pulley may be contaminated with dirt and dust. This would cause the belt to slip on the pulley when under tension / load. I would recommend cleaning the open / close mechanism with an alcohol based solution and a cotton-bud / cuetip - (those things you would use to clean your ears).

Hope this is of some help to you.

ER message for CD, Sharp GX-CH150

The optics assembly is having a problem. Either it can not read the disc at all or the disc is not spinning. In any case, the unit will require service. If you can reach the lens, try cleaning it using a cotton swab and alcohol. That may resolve the problem. If not, update this. Please try to see whether or not the disc spins and report that as well.
