Great sets - the tuner grounds/EEPROM corruption aside. Some customers jerked the F fittings right off the sets, but that too was an easy fix.
Only saw one that had a fatal chassis - the PLL circuit in the tuner - VHF-H worked fine, but VHF-L didn't want to tune. Not even useable with a cable box.
Salvaged the CRT from that one - have yet to use it.
Cheers,
