Mine just did the same thing. Except for it was green instead of blue. The service manual states 8 flashes from the light stands for an overvoltage. After reading the manual for a bit I realized the bottom row of 3 adjuster screws from behind the speaker grill adjust the output for the red, green, and blue colors. BEFORE OPENING ANY TV OR MONITOR PLEASE KNOW THAT THE VOLTAGE INSIDE CAN KILL YOU EVEN IF UN-PLUGGED so please be careful and only adjust what is mentioned here. I un-plugged the tv, removed the grill and the board covering the internals, and carefully turned the 3 adjustment screws all the way down. I then waited about 10 minutes (don't know if this made a difference). I turned on the tv, turned the channel to an auxilary input (for a black screen), and slowly raised each of the 3 bottom screws one by one up clockwise until i could see a faint green, blue, or red line (depending on the screw), and then turned each one back a hair until the screen was black again. Only adjust one at a time, the order for colors are blue, green, then red from the left. I hope this fixes your problems. Be careful when working inside a tv, I suggest not using a screw driver to adjust the screws due to the possibility of it slipping and someone getting hurt.

SOURCE: tv turns self off when turned on
Does it blink a certain amount of blinks pause a second or just blink constantly with no pauses? Let me know it will blink a code if its going into protected shutdown. And it will blink constantly for another reason.

I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions
