If this is a Sony Rear CRT Projection, you probably have a bad Red CRT. The only way to know for sure is to get a professional to look at it.
Hope this Helps,

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.

Flashes blue and then the tv shuts down


The tech is correct about the internal short inside the blue CRT. There is a way to remove that short by applying a small amount of current to burn the short but that might damage the CRT even more. At this point the CRT needs to be replace.
I will post the instructions on how to remove that short but you will need to have a good regulated power supply and limit the amount of current to 1 to 2 amps.
