I bought an ALinco DR 590 dual band amature radio at a hamfest. It is a

mobile. Got it home, hooked it up, everything on the display lit up. I
mean everything, even things that were not supposed to. The frequency
number has stange lines in it. It was not usable.

Figured out that I could reset it. (Pressing function button with power
button) and it would start working again like normal) If I left and
came back even with leaving the radio on it would go back to not
working.)

I replaced the battery and this still did not fix the problem.

Any ideas?



Not sure but here's a link to the sevice manual directly from the
manufacturer. Found it on google.

I'm thinking maybe power supply problem or somewhere in system
control/microprocessor.
Sorry can't help more but I've never worked on one of those.
