CTC-5 issue

[bigaudioal]

Last night I was watching my CTC-5 for about two hours. Had been operating fine the past few weeks. I then saw something strange and lost raster.

I noticed what looked like twinkling stars or starbursts inside and on the face of the CRT. Saw this maybe two or three times within the minutes leading up to losing raster. I had gotten up to investigate and turn off the set when all went black. I did not hear anything unusual at all associate with this. No smells, not pops, nothing.

Yesterday morning I got into a car accident with my brand new 2017 Ford Explorer, was rear-ended by a woman not paying attention or she was texting. So I was in no mood to investigate at all. So just turned it off and went to bed. Anyone seen this condition before and might have a clue as to what to look at?

Thanks.
