1967 Color Sylvania video died (Mod. CF16W)

Yeesh, never saw a CRT go like *that* before. Oh well, at least it was one with the beginnings of a cataract.

Keep your eyes open for a Zenith Chromacolor II with a 23V CRT, no cataract issues and it should be a drop-in swap. There may be minor mounting hardware issues but that's it. They're relatively common and there are probably a lot of NOS units in hiding considering the 4-lead safety cap fiasco.

Yeah, as I said....ghosts in the machine!....How would a CRT crack like that without some kind of impact?
Anyway, sounds like this one is toast, as far as my skill set goes....!
It was worth a try tho and thanks, all, for the advice on this old Sylvania.

Possibly a poor connection between the HV button and the internal coating of the CRT caused arcing and localized heating around the button, which cracked the glass.

Or someone tried to "pry" out the HV Anode connector. In a hurry, I did it once to a 23EGP22 set. 13 days of worry while the customer mulled over dad's $61 estimate for repair (filter cap, a rectifier and an HV cup...), I'd have eaten a picture tube. In the end, she bought a set at Sears. I got to junk the Motorola, and breathed again.

The crack didn't curve - it was straight as an arrow, to the side I had pried from...

I wouldn't trash it, good 23V CRTs are easier to find than Sylvania tube tabletop sets. Swapping out CRTs is fairly easy, it's the setup adjustments that are tricky.

Cool, thanks....I will not trash it.....although I do not know where to find one....
That set was closed up tight....the room is locked, I don't know how anyone would have touched that anode connector....bizarre...!
