> Hi All,

> I initially had problem with TX light staying on
> without PTT being pressed on my TS-440S.
> I changed mic and still TX light on. I tried cpu reset
> but no avail. 
> I pressed SEND/REC on and off a few times and noticed
> TX 
> light flickering. I am not sure if it is the relay or
> some sort of 
> transistor playing up. Sometimes the radio operates
> quite normally 
> and then TX light staying on for a while and
> flickering. Now I can only
> receive. No more TX light staying on. Even when I
> press SEND/REC 
> button on, pressing PTT on mic or AT tune button, no
> more TXing. 
> I don't hear the relay clicks anymore when I press PTT
> or SEND/REC button.
> Whatever was playing up I think finally gave up.
> Could someone guide me to the problem area or the
> particular part that I could replace?
> Thank you to all for your help.
