I have a television with a strange problem. When i start the tv it takes about 10-15 seconds before the picure appears. And also the red color is missing, so the piture is bluegreen (but no lines). And then after about a half minute red fields starts flashing across the screen, and then it turnes off. Any idea what cause this?

Whats the Make ? Sounds like bad CRT .

You should always mention the make and model number of your TV set when posting.
Generally speaking, it sounds like the CRT is most likely defective. CRT replacement in a typical TV set, or computer monitor, generally costs more than a new unit.

Probably a bad CRT. I have an almost mint early 70s Sony Trinitron 13" TV that has a "flaky" red gun that cuts in and out kind of like what you're seeing. Usually when CRT color guns go bad, the red one goes first.
Could very well be something other than the picture tube.

As a test try swapping the drives to the CRT over. If it's the CRT then it will still flash red, if it's something else it will flash either green or blue.
If it's a Zenith you probably have a short in the picture tube, otherwise who knows, you have to post the brand and model for anyone to help you.
