sony trinitron 32"

i found an earlier question very similar to my own. I have a 32" sony trinitron TV and the picture cuts in and out. it started about 6 mons ago and at first it was just when the tv was warming up, the problem has gotten progressively worse. the screen stays black until the tv has "warmed" up for about 5 minutes. then the picture cuts on and off without ever losing sound. it does it a little less frequently as the tv is completely "warmed" up. The problem has gotten very bad now. it is not channel searching. it stays on the correct channel (channel i chose) there is never any change in the picture when it is showing (no color or clarity changes) it just cycles picture/no picture, no matter how long tv is on or how long its been left turned off. i am electronically illiterate so i cant "fix" the problem myself, i would just like to know what it may be, wether it's going to be mondo expensive to have repaired, or should i just chuck it and get a new one. all replies greatly appreciated.

If your tv was made in the 90's, then most likely your picture tube is gone. These Sony tubes have a special circuit which will cut off video just in the manner you're describing when the tube becomes weak. Of course, I can explain the technical side of it, but all you really have to know, if you're not electronically inclined, is that your TV has served its purpose on this earth. Start looking for another one. Sorry for the bad news.

This Tv has what is called and IK curcuit. what that does is wait till all 3 guns are warmed up equally, so you don't get bad color or grey scale when the unit is turned on. Sony and many others thought that was a good idea. NOT ! anyway , you might try to turn up the G2 adjustment on you flyback it is the bottom adjustment. DO NOT turn it up much just a little tit...up wait till the set comes on and crank it just a little.. it has worked in out shop. And as others have posted your tube it on its way out think about buying a new set

There is a fix for this! I have done about six of these units, & they have worked out quite good! You have a bad picture tube, but you need to rejuvinate it. If your'e technically inclined, or you have a buddy who is, I can E-Mail you how to do it if you don't have a picture tube rejuvinator. I have a sure fire way to clean it up. You'll be quite pleased, even if the tube is very bad. I'll look for my notes, E-Mail me. Dani. snipped-for-privacy@gmail.com

Please listen to the experts here: whatever you do to your tube will save it only temporarily and the picture won't be as good. I have tried the rejuvenation method thousands of times only to have customers come back and complain about a bad picture. Solid advice: if you watch tv a lot and want to enjoy a nice picture, get a new set.

I used to flash them with a piece of hook-up wire connected to the ultor and flicked across a grid. Wouldn't try it now.

TV sets are so inexpensive these days that it doesn't pay to do anything with or to the CRT when it gets weak or outright fails. I agree with every poster here. Don't bother with CRT rejuvenation--it is a temporary fix at best, as others have said. Get rid of your old set and get a new one. If you're thinking of upgrading to LCD or plasma, this is the time to do it. Flat panel sets are coming down in price all the time, so you are bound to find one within your budget. If you still want a CRT set, those are almost dirt-cheap these days. RCA's line of SDTVs (standard definition TVs) is also dropping in price every time one turns around, or so it seems, so if you don't feel you are ready for or don't have the room for a large flat-panel TV, an SDTV could be a workable solution as well.
