Sorry to be the bearer of bad news but I have the same model Sony with the same problem it was just returned from the repair shop (not to mention a $95.00 diagnosis charge) I was told that it will cost $700 to repair. The bulb in the back is gone and Sony no longer makes it so it would have to be re-built from scratch. I'm done.....

Unfortunately, the Blue CRT will most likely need replacement. But you can get the entire assembly as a complete unit which makes it a easy removal and installation since the CRT is a complete one. Heres the link to that Blue CRT http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=220790336974&ssPageName=STRK:MESE:IT

The screen turns blue after about 2 minutes of turning on the TV


Sony TVs has an Optical Block issue. If there is an issue with the optical block, then there will be green, blue patches or tint on the TV display. Try resetting the TV to the factory settings and try Power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue still persists, then TV may require service. You can contact the Customer relations team and check for the available options. Sony had repaired free of cost for such issues. Hence, contact the customer relations.

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!

It might not be worth fixing

TV turned off itself


Can you still turn it on?
If so, does it stay on with sound?

If the sound is ok and the picture is blue (even when changing channels, inputs, etc.) the lamp may have gone out.

Can you see the TV menu when you press the menu button on the remote or TV?
