Well, I just went ahead and hooked up the HV to it.

And IT WORKS! It made another loud pop, but about half as loud as the ones in my video. Followed by the normal snapping sounds as you'd expect.

Picture came up and it is working just fine!

Other than you can tell the old tube, despite having 100% emissions, was a bit worn. The screen greyscale is a bit bright, and the focus is a bit off, but much, much sharper at the edges than the old CRT. Even still the old CRT still looked amazing.

So all it needs now is the convergence and it looks like either purity or it needs degaussed in the lower right of the screen.




But as I was getting all excited, the TV decided to shut itself back off and won't come on again. And I know what it is now: That power relay. I've had this TV for 6 years in storage now, and I now remember I did resolder the connections at the power relay to no avail about 4 years ago. I went in and wiggled the power relay and the TV decided to come on! So I resoldered it 2 weekends ago completely forgetting I already did that 4 years ago, and all of a sudden it started working. This was the same night I broke the original CRT. So on with the hunt for a new power relay at this point. Coil appears to be intermittent.


As for the CRT neck cracking on the old tube... I don't know if it had to do with that internal short I got (it was an extremely bright purple when the tube was on) and maybe I accidentally hit the neck wrong with my screwdriver handle trying to see if it made any difference on my tester after realizing I just screwed the tube up. I was not happy that night, and I might have accidentally hit it too hard after giving up knowing there was nothing I could do for that tube... it was toast at that point.



Anyhow, what I just witnessed was a first. I can understand some loud pops from a brand new CRT, but these were extremely loud with those color flashes. It just scared me. But now I know. Lesson learned on multiple things just from this. I will also check the high voltage in this set once my HV probe comes.


I will keep you posted once I get it functional yet again.


Thanks!
