I agree with Jim. Having repaired several of the Omni VI series, the areas
of concern are the connectors that are used between boards and with the
wiring harness terminations. Carefully unplug each, inspect around pins
with a bright light and magnification to assure no solder cracks exists.
Same for the IC's in sockets on the boards. I suggest a contact cleaner
such as Cramolin. But take caution in using any cleaner "least is best".
The put things back together and exercise each connector by then unplugging
it again and re-inserting it. The wiping process cleans the pins, both male
and female.
You can check the data going to the LED displays all the way to the segment
of the LED to see if there is a failure of the LED device or if a failure
exists elsewhere. I am not a proponent of changing parts to see if that
fixes a problem. I much prefer to spend the time to find the defective part
and simply replace that part. The repair success rate is much higher using
this method as opposed to putting in new parts and see what happens. I've
found too many times that folks put in new, but defective parts, or make
solder errors which introduce added problems.

Subject: Re: [TenTec] Omni VI plus Display
Paul,
I have an Omni VI opt 3 that I purchased used. I have had multiple
display problems. When I opened it up and checked out the display board,
it was obvious that a previous owner had re-soldered things. I cured some
problems by fixing some bad solder joints. And there is a small flaky
problem that I haven't found yet (though the rig is currently on the
shelf).
So, I'd suggest doing a good visual inspection of the board... re-solder
carefully...
A second possibility, maybe to try before the other... "exercise" the
connectors on the wiring that goes to that board.
73 & good luck!

While using my radio today I lost all of the segments on the DSP1, right
side digit. So now I get a read out that is 1 .225, 2 .225 instead of
14.225 and 21.225. My computer programs shows the correct freq and I am
TX/RX on correct freq. Have any of you had this happen? What was the
fix?
Any one have a parts radio that wants to sell a LED display board? I am
also looking for the following keys that Ten Tec no longer stocks. REV,
A=B and A/B
Thanks for your help
