this is common issue with this model and through your troubleshooting is tied to y main board. blinking led on logic main in normal operation. when replacing y main always good idea to replace y upper and lowe buffer boards as they complete a circuit and sometimes replacing one without other could cause additional failure on remaining boards
SOURCE: power problem
There was no smell from the power supply. There was a flashing green light on the back of the power supply. Plugging in to other power sources did not help. The solution was to replace the power supply. I replaced it and now the PC is working properly again.
SOURCE: TV quits working, screen goes black and red light next to power green light flashes 4 quick flashes.
The Sony diagnostic routine for 4 blinks indicates it to be a vertical deflection problem.
Did you see a solid horizontal line in the center of the screen prior to it going out? If so, that is a tell tale sign for vertical problems.
basic sony reset below
