[TenTec] ALC not working, Anyone had the covers off?

[Lin Davis]

Lee,

Also, if the O2 is same as O1, then the ALC LED is driven from the same UCN6810 
IC as the VFOA SUB RX and VFO B SUB RX button LEDs. (These buttons are shown on 
page 7 of the Orion II users manual as 12 and 13.)
The UCN6810 PCB reference designator is U7 and is located on the A8 board, which 
Sinisa pointed out is the Keypad Board (front panel).

So if the two button LEDs mentioned are working ok, and the ALC LED doesn't even 
come on when powering up, I would highly suspect the LED itself or cold solder 
joint at U7 pin 12 or the LED pins.

Good luck
