Radio is switched on vibrates and goes directly to a blank screen
As the subject suggest im having a few problems with my cobra radio and would be extremely grateful for some help, bought these radios a week ago one of them works fine but the other is not. As the radio is switched on it vibrates and goes straght to a lit up screen nothing else appears and nothing else happens, i have replaced the batteries for brand new ones and that has not fixed the problem.

Sounds like the radio was subjected to electrostatic discharge. If you have your manual, and it describes a way to do a "master reset" on the radio, follow the instructions. This usually involves pushing down on one key while turning the radio on. Otherwise you have to find a licensed dealer for factory service, as there is no way to repair the radio yourself. The use of surface mount technology still confuses many Techs unless they have been to a company's two or three week seminars.
a mobile cb radio like the cobra 29 requires 12V DC, to plug the radio into the wall you need a Power Supply. A small 5 amp power supply will help you. Their is no plug that goes Directly from a Mobile CB rado into a wall. You will need to plug a power supply into the wall, Then take the power chord (red and black with 3 prong [o oo] and connect red to red on the power supply and black to black on the power supply. Unfortunatly a cheap power supply will be $50+ check your local radioshack
