[1000mp] No output on 17/15M

[Ken VA3KA]

I was going to operate on 17M today and was using the internal tuner to 
tune the dipole. The tuner did not seem to want to tune and took a long 
time. The antenna SWR is not too high, about 2:1. Then when it stopped 
tuning there was no power output on 17M. I checked the other bands and 
there is also no output now on 15M. All other bands are ok.

Any ideas where to look?

Thanks and 73,
