[TenTec] TT-253 Tuner Help?

[CSM(r) Gary Huber]

I have a similar issue when using my 253 in auto-tune with my TH-7DXX on ten 
meters, but it is apparently due to the frequency being tuned and the last 
setting in memory. If I cycle the 253 off then on and then press both the L 
and C rockers to sync the Capacitors and Inductor, wait til they finish and 
then (auto) tune, it will work. On occasion, I may have to go through the 
process several times or change the frequency but it will get it done. 
Another thing to consider is the feed line length;  have you tried adding a 
coaxial jumper to increase the feed line length to the antenna to change its 
natural resonance and VSWR points?

One of my 253 Auto tuners is acting strange. I can tune antenna's manually 
and all meter functions work as they should. When I try to tune using auto 
tune the tuner faults every time. Any quick remedies before it has to go on 
a trip to TT? I have already changed the memory chip and no luck there.
