When the tuner wrap loses it's grounds, it causes the
EEprom to get it's data corrupted. On the older sets,
just replace it and tweek the rf adjustments. On the
newer sets, you can use Chipper Checker to reprogram
the EEprom. I can only use this email at home, don't
have time for it at work. Ask someone for the AFT
align procedure.
