Very likely the Tuner was hooked up to the antennas and endured a build up of wind or snow static charges, which took out the diodes that sense SWR. Check those for shorts or opens first. Is the antenna(s) coated in ice? You sure the antennas are intact at the feedpoints? (In high winds, we often lose the club G5RV connection to one side or the other.) The weight of the cable choke ferrite is just too much for the flat top in wind storms.

Good Luck, usually that is all that has happened unless you have some RF amplifier for the SWR/ tuner logic circuits.

Happy Thanksgiving to All!
