[TenTec] Orion II looks DOA!

[Paul Rubin]

Ron:

I had the exact same symptoms after an Astron power supply failed and fed my
Orion II 28 volts.

Schematic A0 81908_5 shows the power conditioning input circuit. In my case,
D116, a 16v Zener failed and shorted to ground through a 1K resistor.

Although you say the power supply is fine, I would still check this out
first. 

Good luck,

I'm afraid it's happened...my Orion II may have bitten the big one!  When I
turn it on, I get the half-bright meter face, but then nothing else happens.
It stays like that forever with no LED's lit and nothing on the screen.
Power supply is OK and I measure +14 V on the accessory output on the back
of the radio.  Anyone else ever see this sort of behavior?
