2 blinks on this set indicates a power supply issue. Your power supply board is very likely faulty. This is common on these newer flat panel sets. This fault is usually caused by bad capacitors (leaking or bulging) on the board but could be also some other components or combination of issues with that board.
The usual fix is to swap out the board. Here is one: http://www.shopjimmy.com/sony-1-474-211-11-power-supply-unit.htm?gclid=CKeziJi4m7cCFQcOOgodFxgA_Q
If you do not feel up to doing the work yourself, a technician will charge you about $125-$150 in labor plus the cost of the board.
I am sorry that I don't have a quick fix :( Any time you get a blink code on a set like this, it is not good news.
I'll be here if you need further help.
Dead easy. If you have built a PC, you can do this with your eyes closed.
Take the back off the TV, ID the board, disconnect it, remove it, put the new one in, connect it, put the back on the TV and you are done.
