Hi , I have a silent whistler 900 cb radio.
It lights up but no RX or TX .
Right side channel readout has a couple segments out .
It did work at one point but quit !
Info on this is scarce to zero .
Rigpix schematics are very blurry .

Any experienced techs out there ?
Thanks , Craig

Amber is hard to come by, I thought they were more of an orange color. Might want to compare them to the Cobra 25 displays, you can get them in red and blue.
