I`ve got a new cobra 29 LTD classic, I would really like to replace both the lcd channel display, and the meter light to a different color. Have quite a bit of backgroung in auto wiring repair. Is there any info on this procedure that you know of, or is it pretty straight forward.
I`d take it to a shop, but there`s none local, I`d have to ship, heard too many horror storys
Hello, the channel display is kind of touchy, as far as getting to it and of course it is soldered to a small circuit board and there is a certain way it goes back in. There is about 9 legs on top and 9 on the bottom that need to be unsoldered and resoldered( carefully). You can buy them in red,green, and bue. The meter light is pretty straight forward. You have a hot and ground wire. I used to use colored LED lights in the meters, way cool. They are not hot, and they last almost forever. The LED's are fairly easy because if you hook it up backwards, it just won't do anything. Let me know if you feel comfortable doing the solder work, and take a look inside the bottom cover at the channel selector because it has to come out with the channel readout. I used to charge $25.00 just for that because it would take me an hour just for the ch. selector, and about 15 min. for the meter light. Let me know one way or the other,,, Mechanic

Check TR22 which is a 2sc1957 transistor mounted on side of case near heatsink for driver and final, left rear with speaker cover removed. Make sure the legs are not contacting case. Then check resistors R115, R116, R117 for open circuit and C133 for continuity.
I figure that 2sc1957 transistor is shorting to case or failed. A 2sc2314 is a sub for this transistor.
Did you have someone get on channel 2 to see??? Maybe channel 2 was quiet and channel one had better receive or noise.. You never know until you check it with another radio. That is NOT a common issue at all on those radios. Better off doing that test. "WILDCAT" IN LAURELVILLE OHIO 35 YEARS OF CB FUN!!!
check the squelch by turning all the way both ways. check the external speaker socket. if it is the swicthing type it could be either bad conntact or dry joints. try an external speaker to see if that works. another thing is I believe it wont work if the microphone is not pluged in or connection fault there. Good luck.
Had fixed the same problem yesterday. My cobra worked when it wanted to, when it didn't it looked like you explained. I found out that on my cobra the blue wire on the mike connector was broken. When it disconnects, no sound. after soldering, everything works fine.
