Hello all,

I've got a tricky Aiwa CX-NAV66EZ I'm trying to repair. It has some odd
problems:

When plugged in, the unit may power up briefly during which time the
relay clicks a bit madly then it goes dead (display goes off).

Other times, you can plug it in and it stays on, doing it's silly
"demo" thing, but when you press the power button or one of the
function buttons (CD, tape, tuner, etc.) the display reverts back to a
simple clock and won't come out of it again, no matter what buttons are
pressed.

It has also been known to go on and off perfectly, but after about 15
seconds from plug in, whether you switch it on and off on the front
panel or leave it alone, the display suddenly dies and leaving it
unplugged for a minute or two is the only thing which will make it come
back to life when plugged back in again. It's not doing this at all
anymore though.

Also, whenever the bugger did come on properly before dying, the volume
control was not working properly. It would barely alter the volume
digits or they'd flick back and forth. Don't know if this is linked.

Any ideas before it gets thrown over next door?

Thanks.
