Ten-Tec Orion Replacement LCD
(info posted by Chas N4FW to the Orion reflector 22Dec16)
Newhaven Display model NHD-320240WG-ATMI-TZ# will work, but you'll have to fabricate an adapter to connect the display's ribbon cable to the Orion logic board. I installed one in my 565 a couple of years ago.
The display is available from Mouser, Digikey and directly from Newhaven for 68 bucks.
If the NHD-320240WG-ATMI-TZ# display is installed, disconnect the -20 volt lead on the A9 power distribution board before applying power.
