    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.

Ps3 afterglow bluetooth flashes red and blue and wont let me talk, what do i do?

When the afterglow headset flashes from red to blue, it is in pairing state, youve held the power too long after power-on. Shut it off again and turn it back on and dont hold the power button untill it flashes red to blue. The directions provoded with it aare quite easy to follow. Took me 30 seconds to set mine up

Computer turns on to the windows screen and then a blue screen flashes too fast to read what it is saying. It then opens to a black screen with several options :open in safe mode, last known recovery, etc....

Usually blue screens are caused bu problems with hardware. Since the laptop was dropped, I would suggest opening the access doors and taking out each removable component and then reseating them back in their positions. It sounds like perhaps something has been jarred out of place such as a memory module, hard drive, etc. Start with those two and try to boot the laptop after each try.

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.
