I have a trouble with my old TM-2550A.
When I turn it on, the unit does not show the display, only the red TX
light turn on without pressing any button, even PTT.
I tried to reset the CPU shorting the two pins located on the lower
board. Also, I measured the CPU battery backup, showing 3,2 V aprox.
(after 15 years?).
I have the TM-2530A, lower wattage of the same radio. Had the same
problem with mine - it turned out to be the connectors between the
'head' (front panel) and the main board. With the CPU facing up, the
wires are on the far right side of the board. Clean the connections
and pins, you should be fine.
