Re: blue light in the front blinking no picutre no sound
This is the shutdown code for the lamp ballast. I would have a technician verify ballast is bad and replace. This can be a tricky repair for a novice because installation of the ballast requires that you remove the light engine. Hope this helps.

It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen. Do you see standby red light blinking when TV shuts off after showing blue image for a while? If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution. Thanks.
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
