Question about Sony KV-35S36 35" TV
The most common cause for what you are seeing is a shorted gun in the picture tube. When 2 elements (heater and cathode) of one of the guns inside the neck of the picture tube touch, that gun goes full on and overloads the flyback (high voltage) transformer. If it is in the blue gun, the screen will go bright blue with light blue "retrace" lines in it. The computer senses the overload and shuts the set off. At 2 years old the tech most likely tried removing the short by arcing between the elements. This works sometimes but the short often comes back a few months later. Another attempt at removing the short could be tried, and it might work this time, but it may or may not work for long. The ony other solution is to replace the picture tube but that would cost much more than the set is worth. A qualified tech will be able to tell you if this is the problem in your set.
