I hve worked on a number of these units , your description is typical of a shorted blue picture tube. The protection circuits in the tv detect that there is a problem thus shutting the unit down to prevent further damage. Sony had a bad run of picture tubes in this series. The replacement cost of the tube is about $250 plus labor. My estimate would be for the repair about $400-500 depending on where you live and how honest your local technican is. I will caution you however, that you could replace this tube and the red or green could go. These would not be covered by the technicians warranty. When these sets are working, they have a superb picture and it is easy to get lured into fixing them. Scrivitron

Pioneer Elite PRO-1140HD blinking stand by light - can turn on, blue background comes on for five to ten seconds, TV then turns off and stand by light blinks. I know it is a circuit from the motherboard, can I fix it myself? Would you be able to provide me with parts and how to change it?

Sony blinking codes

If i remember correctly ten blinks means a high voltage error.
The only thing you could try is unplugging the power cord then plug it back in and try turning on the tv. If it still won't turn on try unplugging the power cord for five hours or longer and try again. If it still won't turn on it would be best to find a local repair shop that works on sony tv's and have them repair it for you.

Tv wont come on and a red light is blinking. I have a Sony Wide screen projection TV model kp-46wt520

Can you unplug the TV for about 15 seconds, and then plug back in and watch the stand-by light. Tell me how many time the stand-by light blinks in regular intervals. If it doesn't blink at all, you need to change a fuse on the g-board. Once this is done run back through the stand-by blink light process, and more troubleshooting can be done if problem isn't already solved. If the stand-by light just keeps blinking with a count over ten just tell me, and I'll look for other possibilities.

Minium is the green picture tube need to be replaced, if you can take the front cover and access panel off there is a control with 3 focus and screen controls.
you can adjust the 3 screen controls to possibly get a little more time out of it before the crt's need to be replaced. careful if you turn them down too much there will be no picture, and if you turn them too high the tv will go bright and shut off
