Anybody familiar with Television repair? (1 Viewer)

I'm not expecting an answer, but it's worth a shot.......

I have a 20+ year old sony trinitron 19" telivision. It's a nice tv, but it has stopped showing green altogether. At first, it would come on and off intermittently, but now it's off all of the time. I thought it may be the green tube's cathode is burned out, or maybe has a short or something. Does anybody have some suggestions on what may be wrong?

nevermind. I did some troubleshooting of my own, and found that the green gun is dead, time to toss the tv.

I have had tremendous success rejuvenating old Sony DVs. I use the Beltron, but Sencore also makes a good CRT rejuvenator.

Inquire at your local repair shop. This was really a big thing, years ago.

Way more trouble than it's worth. Set's dead. Mourn briefly and begin searching for a modern replacement with amazingly superior performance at only a fraction of the price.

Why would no one want to answer your question? This section of HTF thrives on good questions.

Today that's true, with the glut of TVs on the market today.

There was a time when TVs were very expensive, and rejuvenation was an honored way of saving a TV.

But now, yes it's as you say, and I couldn't agree more...

I have a small chip or crack on the tube of my direct view HDTV. Do you fellas have any idea on how to fix this inexpensively without replacing the entire tube?

Looks like a chip, since the tube is about half an inch thick, and a crack would be very unlikely.

Perhaps filling it in with some kind of permanent transparent goo, like superglue, or clear epoxy. Something that will set up smooth, even tho it probably will cause refraction error. Lucky it is not in the center of the screen.
