Flickering red in Sony KV-1311CR

[Phil Nelson]

After 20+ years of regular service, my beloved Sony KV-1311CR TV/monitor has developed a problem. It's like the red gun completely flickers out. Sometimes it comes back on in a flickering way, and then the picture is fantastic again. Adjusting user controls (Color, Hue, etc) has no obvious effect.

Is this a typical symptom that the CRT is giving up the ghost? I haven't hauled it back into the workshop to test the CRT yet.

This is the original CRT, so i guess it wouldn't be remarkable if it's finally dying. In that case, Where Oh Where would I look for replacement? It's such a perfect size for my office desk that I hate to give it up. About a year ago, I fixed a video problem by replacing some electrolytics.

The photo shows the TV when it was working properly. I just included it to give a general idea what model this is.
