You TV has a bad CRT, a red CRT by the sounds of it. This TV is rather old, perhaps 11-13 years of age? Your TV has given you many years of service and I do applaud you for the care you have given it and the TV for it’s reliable in your home. The trouble you face with a rear projection CRT set of this age is that you can’t just change 1 CRT tube and expect it to be reliable and produce a good picture. All 3 tubes should be replaced, as they have all aged the same. The lives of these tubes are only about 7 years. A tube is not any easy or inexpensive repair on any RPJ TV. When you are faced with the cost of 3 tubes, which may not even be available in the market place… You should consider retiring this old friend and keep the manufacture in mind as you make a new purchase.

Testimonial: "not sure what CRT is though as you describe it,it sounds terminal. 1997 is the manual I have for this tv. at this time repair would be most desirabl"

Turn on TV and picture and sound are great for about 60 seconds. Then the picture disappears but sound remains.

I would start with checking the power supply 12vdc output, make sure it is stable with no ripple. If the power supply checks out fine, I would then suspect the main board.

The picture and sound on my 55 inch Sony disappears momentarily

Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast. But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is XL-2200.You can find it here: http://www.discount-merchant.com/Sony-XL-2200-TV-Bare-Lamp-Bulb-p/sony_xl-2200u_a1601753a_lamp.htm?Click=48173 Have a blessed one!

My HyVision LCD TV Picture disappears after a few seconds

It seems that the "backlight" has gone bad. "Backlight" is the device that allows to see the picture in an LCD TV, when they are about to go bad the symptom that you describe is very usual. It depends on the tv manufacturers and model to expect how long the "backlight" is going to last in a tv.You can shop around for a replacement part and try to do it yourself or take it to an especialized technician. Good luck..

Toshiba televison picture keeps going yellow

Sounds like the blue is disappearing from your picture. A common cause of this is bad solder connections which can cause the blue signal to be lost at several places. It could also be due to picture tube failure. Sadly, I'm leaning toward tube failure because of your description. Bad solder connections usually take some time to start acting up after you turn on the set, but you say this happens every time within a few seconds. This is typical of a picture tube failure where an internal connection is okay until the tube heats up, and that takes only a short time. A service shop could check the set to make a firm diagnosis, but if the tube is the culprit you should replace the TV. It's not economical to consider tube replacement.
