[TenTec] Orion display..time for replacement

[denton]

Thanks to all that replied...here is a follow up...hope it makes another 
hams life a bit easier!

I received a new lcd display, battery and regulator board..since I had to 
replace one of the bulging filter caps on the original regulator board 
thought would replace it with a new one. Since my Orion is fairly old, 
replacing the battery was a no brainer to me.

Removing the old lcd was pretty easy...used a wooden pencil to gently  pry 
the boards apart...man, sure are a lot of pins between those two boards!!

Replacing the new lcd and alinging the pins was a major PITA!! Next time I 
wll use some tall bolts, without heads, threaded into the holes in the cpu 
motherboard and use them for a guide for alinging the pins on the new lcd 
board-

The new lcd came with a cable that is installed in lieu of the old lcd's 
multipin plug....as per the articles in the below wiki website, one must pay 
close attention to cable installation...and I would suggest re-reading the 
instructions several times, as in my case the blue strip on the connector 
ribbon dictated that the ribbon cable needed to be installed upside down 
from what one would think would be normal connection. I also clipped about 
1/8 inch off of the pins on the cpu board where the new ribbon cable 
installs, as per instructions I got with the new lcd from TT.

On the reguator board, there is a dip with cable that goes normally to the 
lcd. It is a 20.5 vdc line...do NOT connect this cable! There is only one 2 
pin socket on top of the regulator board, so it is kinda hard to miss.

I also installed a 10 ohm resistor in the red wire going to the backlight to 
better the contrast on the new lcd.

Since I replaced the lithium battery, things were kinda goofy for a 
while...a couple of master resets and reboots finally got things back to 
snuff.

Now to find what dohickey wants to make funny noises on bootup when the rig 
is cold...sounds like a "bweep, bweep, bweep noise when antenna is attached 
and feq is on a psk signal or a carrier.None of the sidebands sound right. 
After a brief warmup and reboot, the rig acts normally.

Kinda makes me miss my long gone HW101, despite it's appetite for  audio 
tubes!
