Samsung picture tubes!

I have seen two Samsung T.V.'s with bad CRT's just lately Model # TXJ
2754, TXJ2750
A68ADT25X01 CRT in both cases. Arcing orange inside. Like the vacuum is
gone out
of them. Anyone see this in this CRT # ? Also, where do I get a CRT
cross reference
with newer CRT's? Looked online allover, & "Googled" it. Can't find one
with anything
higher than A68AEC00X, to cross with the ones I have found bad. Thanks,
