Uniden PC66 CB Radio no Lights or Power Trouble-Shoot and Repair Video 

That chassis looks the same as the Realistic TRC 427 and Cobra 25 GTL.

Here is my repair system. I start with ignorance, go to stupid if that fails, and on to pure dumb luck as a last resort.

I find it easier to unsold the speaker

Once you desolder and lift one leg of the diode (D17 ? ) the radio should light up.

Hello sir i have a tyt th9800 cb radio I have to change the diode I don't know witch one to use can I use any of them..??
