Step1
Start CB radio repairs by checking the state of the On/Off switch. Many CB radios with no transmission can be repaired by replacing a faulty On/Off switch.
Step2
Fix a noisy microphone by applying light oil to the contacts. The CB radio's knobs can also be maintained with the oil which will improve performance. If the knobs are loose, remove them and open up the slot a little. This will decrease slippage and reduce static.
Step3
Check the microphone sockets and aerial sockets. The sockets should fit snugly and not wiggle around. Open the sockets carefully.
Step4
Tighten all screws. This is a simple step but can eliminate many transmission and reception problems. Do not over tighten the screws.
Step5
Replace any cracked components. Damaged components can cause intermittent outages for months before they fail. To avoid long interruptions replace all cracked elements.
Step6
Clean the chassis carefully. Dust and grit can accumulate and cause a build up of heat and clog fittings. Tighten all fittings when finished.
