Sorry for delay in followup to group on my problem.? Lots of more
pressing recovery issues in the shack.
Pasquale (IW0HEX) was correct.? And the other replies that
suggested the issue was likely near the point of entry were also.?
As previously said, the menu items, power output (by keying on
CW), etc are normal.? Since Pin 3 (HSEND) is an input/output
control, I applied the +2 to +20 volts (high range) to the HSEND
(pin 3) and the rig goes into receive.? All receive functions and
sensitivity appear normal.
The .png didn't come through on his original message, so I have
asked Pasquale off the group to send me the part number for that
resistor.
Not sure I'm up to the task of such small work anymore, but
figure some local friends with better skills can help if need be.?
Will close out at a future date, when all is hopefully back to
normal.
Thanks for the replies.

Some times ago I repaird an IC-7000 with
the same iusse, Led TX Red always on.
The owner said me that issue was during a
storm with lightning and he used a item link on ACC port. I
thought there is a issue on logic board and it was right.
Check on SEND line to ACC port from logic
board (CPU), you will find a pullup resistor; I found this
resistor opened so SEND line in RX wasn’t on 5 volt but 0 and
the result was LED TX on.
Sorry for my english.

Hi.? Looked
for any past posts, but didn't find them.?
Before the problem below developed, all control cables and
coax disconnected (due to approaching storms), I have a
disconnect area outside the house about 20 feet away.? I place
the "house" bundle about 2 feet way from antenna area bundle
of coax and various control lines to rotor, switches, etc.?
SUSTAINED a lightning strike on the densely wooded hill behind
me, may have hit an antenna, all 150 feet away.? But you could
smell burnt wood, so some tree was hit.? Steep, rocky climb so
not been up there yet.?
Results:? Wire damage and blown connector to the outdoor phone
cable used.? This at the "disconnected end" of that remote
switch run.? No other visible damage.??Inside, besides coming
out of the chair from sound/flash from strike, no visible
damage.? The lights barely blinked.? Multiple TVs, electronics
in the house, and ALMOST all the equipment in the shack is
still fine.? (1) The?station PC is dead.? YES ... audio, data,
etc cables, connect EVERYTHING else in the shack to that
PC.??Not the power supply, so the motherboard and beyond
suspected.??
But to the point, (2)?the
backup IC-7000 TX light stays lit RED, no
sound out of speakers.? ?Output is fine.? CW keys.? SSB voice
peaks show.? RTTY & FM go to normal power out.? All
navigation through menus is normal.? I did a hard reset but
same situation after that.? All connectors to the rig removed
except for antenna coax -- and key during CW test, and Mic
just for SSB test.
Any ideas?? Since all functioning of the unit otherwise looks
good, power, processor, etc. ...? I hate to send it off before
asking here.? Thanks.
