[Kenwood] TM-241A

[Bruce Carroll]

Dear List Members:

I still like my TM-241A for 2 meter FM. I would appreciate your help 
in diagnosing my latest problem with it.

I successfully installed the "battery mod" that replaces the 
soldered-in battery with a removable battery. That works (or worked) 
fine. Then I noticed that the push buttons on the front panel 
(Function, shift, tone, etc.) were staying in and not releasing when 
the button is pressed. I removed the front panel and found that the 
foam that was used to put pressure on the pushbuttons had 
deteriorated, so I tried to replace some of it. When I put the radio 
back together, the buttons worked, but the radio seems to have gone 
into a "frozen" state.

The display shows: 1- (to the left of the frequency readout), then 
4.000 in the frequency readout, and then *C in the channel space on 
the right. I cannot change anything; as I turn a knob or press a 
button, all I get back is the "beep." I've tried to reset the 
processor using the instructions in the manual, I have removed the 
battery and then replaced it. I've tried a power on reset with any 
button combination I could think of, but it still does not change.

I hope someone out there reading this will have some ideas on what 
the problem is and how to fix it. I've found these forums provide a 
great wealth of knowledge.

Thanks for your help.
73,
