Unresponsive Button HT1250

[pairughdocks]

I have an HT1250 VHF radio that was given to me to take a look at because a button is not reacting at all. It is the "select" button if you will right above the P3 arrow. I checked in CPS and dropped in my default codeplug I made so the radio does take the programming.

I opened the radio up and all of the ribbon cables are clean and connected. Typically, when a button is unassigned it makes that annoying "beep" sound (like when you have an Rx only personality and try to Tx). This button does nothing and makes no noise.

What else can I do to troubleshoot this issue? My local Moto shop quoted me a base estimate of $150-$300 saying it would probably have to be sent to the depot, and if at all possible I am trying to avoid having that happen.

Thanks for any and all input!

Find the traces for that button on the PCB, close them temporarily and see if the radio interprets that as a button press....if you get a beep, then you have a bad button trace on the board.

Replace the keyboard, part number 0104018J54.

List is $25.

Thanks for the quick replies guys! thebigpush, I am a little unsure of what you mean by find the "traces" - are you referring to the "silver" lines that the solder goes to on the PCB? How would I go about testing them?

K8TEK, I can definitely try that as well. Would you reccomend cleaning the ends of the ribbon cable with pure isopropyl? I do not want to cause further damage to the radio.

Thanks again!

Have had major problem with those keypad boards after the radio has been dropped. We just replace the board.

must be the earlier version keypads.. had many problems with the opamp and traces.. been replaced with a newer keypad board and pay the $25.00 for a new board!! less headaches
