Lightning strike to a Sony Bravia KDL-37m4000

Only testing can give you the answer.

I think you need a new power supply. You can test it by using a multimeter

yes the board is available at the following link http://tvrepairworld.com/sony_lcd__plasma_tv_circuit_boards
the board with the HDMI on it is listed as the Sony FB3 Board 1-873-850-14

I am sure the tv is shot from the surge but you can check a few things. I would take the tv apart and test the power supply first. Look for obvious burn damage throughout the boards. If there is a blackened one (prob video board) then you can try to replace that. Don't worry about taking this apart and breaking it further. In this case it can only get better for you.

my sony bravia kdl-37m4000 have timer pc/off blinking red.

The only fix is to replace the panel and that would not be cost effective. It would be cheaper to buy a new TV.
