    I have similar problem with my KP57WS500 Sony TV. When I turn it on, a green squiggly line appears, then disappears, followed by full blue screen falashhes, then quites. light flashes 8 times on front panel. Is it doomed, or can I save it? I am mechanically inclined and can follow a troubleshooting tree if provided.

    i have had the same issues with my tv the first time it was the red tube and know it is the blue tube, i believe i will be looking for a new tv 500.00-700.00 to repair is not worth it , i think that sony should be recalling or stand behind there product this is a big expense on a 4-5 year old tv. i will be looking at a different brand that's for sure .

    I have the same problem...Turn TV on...have sound and picture for about a minute...flashes blue, goes blue screen, and then quits. In addition, for about two years I have had red curvy lines across the screen...paid $2400 for this TV about 6 years ago...not very happy with the product...unusual for Sony.

    I have the dark outer blue, with a lighter "flashing" blue radiating from the center. I can change channels and I have sound. I can also bring up the menu...but that is it!

My t.v. works fine when turned on I get picture of what I'm watching but ever so often blue light/blotches flashes through the screen in various areas of the screen while I'm watching t.v. The t.v. does stay on and I still see picture but with blue flashes of light coming in and out of the picture.
It seems to get worse as time goes by. I have a Samsung rear projection t.v. Please help.

Post your model. Sounds like the blue CRT is shorted. But let me know the model and I will let you know how to test it.

Hitachi projection tv quit

Pls check that model number........the problem description does not match that of a 1999 crt proj tv.........I believe yours is a newer lcd projection around 4 or 5 yr old?? Lamp light flashing on any brand is indicative of the lamp not lighting . The lamp is the most likely cause,but the ballast board can cause this as should see an access door refer to owner book of the correct model and you can replace may cost around $200 and avaiolable at encompass parts .com Hitach distributor

TV screen Flashes blue and then shuts off.

When it flashes blue, are the flashes bright blue lines going across the screen with the picture in the background, if so, It sounds like the Blue tube or blue driver circuit is breaking down after a short period of time. If this is the case, the uPC that controls the set is detecting a large current drain on and is shutting the set off for protection, An engineers expert eye is required I`m afraid. Ian.

Rca D52W20 blue screen when turned on

Almost certainly the blue picture tube is bad. This is a huge job to replace and quite expensive. Generally it is not worth doing.

Screen all blue

Try looking into the blue CRT lens while its on and see if the coolant has congealed. You will be able to tell if it has bacteria growing as this can cause the blue to be unresposive and make your screen have a blue haze. The coolant will need changing if this is congealed with bacteria. This is a common problem in all projection tvs blue and green are more prone to this sympton red is not.
