Them are deffinately burnt. How did that happen you need to figure out what caused it before repairing or it will happen again. Usually over voltage or a short circut will do this and usually is an end result of other part failure so it needs to be looked at to determined by trouble shooting to figure out why it happened to begin with that looks to be on the power supply side of the chassis that deffinately got hot Justin is good with these in the communication expert forum or at Communication Experts 951-680-0618..

yes this can be fixed

is that the final?

that looks to be the power supply section .doesnt it have a 12 volt plug in the back as well??if it does hook it to a power supply and see if it still works that way ....i,ll bet it does

broken

radio powers up fine ac or dc but no recieve or out put seems to key according to the red green light but no out put. that burnt area gets real hot real fast when i hold key down
radio was given to me in this shape so im not sure what happened to it????????

AC/DC transformer is bad. Seen a bunch of these in base radio's. I've got a bunch of radio's that work great on DC power, but I can't find the right transformer to fix the AC side.

His last post said it powers up fine, so the transformer is apparently ok. However, the burnt parts definitely indicate a past, if not present, problem. As for the TX and RX both being out, I'd suspect either a problem with the power supply/regulator section on the main circuit board, or something amiss in the PLL/VCO (synthesizer) section. This will almost definitely need to be serviced on a tech bench someplace.
