alinco DX-70t transmitter problem
 

I have a alinco DX-70T that got indirectly hit with some lightning, It
wasn't disconnected during a lightning storm and the antenna was large
enough it picked up enough static electricity out of the air from the
lightning that it fried something in the radio. So the radio was still in
warranty so I sent it in to get it fixed and I was told there was a small
SMT diode that was zapped. So they fixed that and sent it back to me. At
the time i was only operating on 160,80,40 and so i didn't really check it
out on the other bands, but it appeared to work great on those bands.
Later on, once the warranty was good and expired i started branching out
into 20,17,15,12 meters only to discover it doesn't work on them. It
appears to receive just fine, but the transmitter goes crazy.

To explain it does the following:

without any good test equipment the following description is the best i can
do.

on 17m sometimes it will appear to work fine, but during transmitting SSB,
the display will blank out the frequency until I unkey and it will quit
transmitting, on 15 and 12 the best i can describe it is it must not be
putting out a 50Ohm load, I hooked it up to a automatic tuner that I
verified worked on the antenna and the frequency with another radio and
with the alinco the tuner just tuned around forever and never could decide.
Also with a swr bridge it would show to have a very high SWR and the SWR
would fluctuate while transmitting on those frequencies.

Once i get up to 10 Meters is appears to start working again, but i'm not
too confident in it.

Any ideas i'd love, i opened the thing looking for anything black and
coudln't visually see anything "BAD" but there is soo much SMT stuff in
there i dont have a clue where to start in this thing.
