APX Replaced APX8000 RF Connector

[tech2223]

Good-day,

I replaced the RF connector because the center pins was broken, now the radio display is stuck on zone C and the top control A, B, and C switch has no effect, also the clear secure switch display is stuck on secure, with it's switch is not changing state either, and finally the programming for the channel selector switch does not display the data in the code plug setup. I have checked the cabling and I am fairly certain it is correctly re-installed. Whatever help you could provide would be appreciated. Thanks in advance.

HTH the center pin break on RF connector. I would suggest maybe taking it back apart and start looking at the flex cables and the connector's for any damage between boards. Plenty of Light and Magnification. It may be a cheap simple fix. If anything is damaged you got an expensive fix or paperweight.

Sir/Madam, while I am new to Motorola equipment, and digital radio networks in general, I do have a some experience in troubleshooting electronics, so I ordered the RF connectors because it seemed to be a simple fix. Now I am on the troubleshooting learning curve, without it appears any detailed tech support. Motorola doesn't really support repairs to their radios. So here I am, in search of solutions. This all started because the person I replaced didn't have much knowledge of test equipment, and hooked up about six radios incorrectly to the 8800SX before realizing they had the wrong test fixture and broke the center pin on all those RF connectors. I agree with your reply, always start with the most obvious first. I will check for correct reassembly of all the boards and cables. If everything is hooked up properly, does anyone know of a source that can provide more information on troubleshooting APX800EX radios? Thanks for your response!
