Sounds like the picture tubes are failing,common on sony. do you notice any thin horizontal lines? You mite get lucky and be able to adjust the voltages. Remove back cover and look inside to see which tubes are lighting up.The front panel below the screen will come off and behind it is a small access cover.remove it. there you will find the voltage controls (its a plastic square with 6 knobs). 2 knobs for each tube, 1 is focus the other is the voltage labeled "screen". they are marked so look closely. Green is always in the middle but sometimes they flip the controls for red and blue so pay attention to which you are controlling .slowly adjust screen voltages to see if you can get it to stay on. If you over do it those thin horizontal lines will pop up and the tv will shut off again. If you already have lines back off the voltage by turning knob to the left slowly until they diappear. If that seems to fix it but the problem but it comes back later, then the tubes are shot. good luck!

    Right on Guru. Not too much of a turn at all. I think I'll go flat screen when the tubes finally **** out. The TV and whole surround system came with the house. Take advantage of the economy if you can.. :-P

Re-insering the flyback wire is usually very easy. Push in and give a slght turn and check to see if grabbed. It sounds as if there is more issues than flyback wire. TV should turn on without one crt connected

Tv comes on for a few minutes then goes off


If you take off the front bottom panel of the tv wich is easy. Then you will see 6 tuning knobs at the bottom middle of the tv .the top 6 control contrast for the lights dont mess with those. the bottom 3 are the power to each light.red is bottom left if your screen went blue it makes sense that the red is starting to go but if you turn down the power to it left 1/8 turn it should fix it for awhile .Its easy.

Do either the red or the green crts come up at all?? If not the heaters in the blue crt could be bad - loading down the HV and the shutdown circuit turns the set off.. Only repair for that is to replace the blue crt, but I would have it tested first.. In the shop here we use a B&K467 to test for shorts and emission leaks but that's old school.. B&K has since come out with far superior crt tester/rejuvenators..
