Will not turn on. Other 1 works fine. New batteries. Radio like new, little use.
Ted, I have pondered your dilemma. When you say the radio is "dead as a door nail", are you saying it will not power on at all? If so, the problem has to be with the battery or battery connection. This radio is not a repairable radio, and there would be nothing about the circuitry inside which would be user repairable. I do think your solution might be much easier.
If you are using a rechargeable model T5725, you can try a simple test to check the charge capability of the radio. Plug in the charger to the charge port and turn the radio on. If the radio does NOT power up, then you have a battery contact problem. If the radio does power up when using the charger, but not without it, then you have a battery problem. IMPORTANT NOTE: DO NOT transmit or push the PTT while the unit is plugged into the charger. This can cause serious damage. We are only recommending this as a test of the power system.
Other thoughts concerning power would be check your battery to see it is in the correct direction. Check the contacts to see if they are clean. If not, use a pencil eraser to clean them.
If this does not help, post again with more information. Read More At : Talkabout T5720 (7 Channels) 2-Way Radio...
