<font face="Verdana">A bit more reading has lead me to believe that
the internal fuse (which I was not able to find on the schematic)
is for the external tuner interface.<br>
<br>
My days as a bench tech were a few decades ago (Wang Tewksbury)
and I lack anything beyond a cheap VM. I'll going to be bold and
pull the covers off today and have a VERY CAUTIOUS poke around.<br>
<br>
In the meantime, I've got my eye on a IC-756proII on Craigslist
for a decent price... <sigh><br>
<br>
Thanks & 73, Jim.<br>

I've seen a reference online to an internal fuse. I have
downloaded the service manual and will review.<br>

is much sadness around my QTH today... I think I
killed my TS-2000.<br>
<br>
I've had my TS2000 for a few months now and I'm loving
it! The only issue I've had with it was on a very hot
day last month it did shutdown (power off) during
xmit. It came back on almost immediately. It happened
a few times that day. I caulked it up to a thermal
protection shutdown.<br>
<br>
Today, which was quite mild by comparison, it happened
again. Only this time, it did not come back on. It is
completely dead - no response to power button at all.
I had done a pretty heavy FT8 session earlier in the
hour (I work FT8/4 almost exclusively) but was working
a POTA site on SSB at the time of the shutdown (sorry.
HI8PAP - I didn't mean to disappear in the middle of
the QSO!). The fan was running at the time, which is
normal, but the radio did not seem at all warm.<br>
<br>
I've confirmed the voltage on the supply cable (at the
radio connector), disconnected everything else, and
tried a Full Reset - nada. The AT was activated and I
had recently done a tune on the active band. The SWR
meter on the radio barely moved during xmit. There
were no obvious 'POP's or signs of the magic smoke,
just the normal power-off sound.<br>
<br>
Is it dead, Jim? Anyone know a good repair tech?<br>
