Has Uniden or anyone come up with a solution for increasing the contrast in
the 780 display?

I am also looking for an XM radio PCR model if someone has one for sale.

Thanks

Jason

From http://myweb.accessus.net/~090/bc-780xlt.html:

There is no variable contrast control in the 780, however, on the display
board, near the middle, you will see an 8.3K ohm resistor, marked "832".
Changing this resistor will affect the display contrast. The optimum range
seems to be about from, 7.5K to 10K. It's a fairly narrow range, so its easy
to see why some displays may be a bit off peak. Remove the 8.3K and replace
it w/ a variable trimpot of say, 5K, with a 5 to 6 K in series. Be sure to
anchor down the new configuration or you can expect it to come loose from
vibration.
