Joe, wanna look at a ZAON MRX?
My ZAON MRX no longer displays messages properly. Whereas the LED display used to offer information concerning nearby airplanes, now the LED display is gibberish.
I re-seated the ribbon cable connecting the LED display to the main board to no avail.
If you would like to look at it, send me an address and I will mail it. If you can't fix it, you can keep it for parts but if it can be fixed at a reasonable price, I'd like it back. Thx Joe. Send info as required.
