sony kd-55x9000h red led flashing 4 times.

Hi my sony 55 inch tv is flashing the red led 4 times saying there is a fault .When i removed the back panel the led driver board green light is on then started flashing 2 times and the red led on the driver board flashed 3 times .Sometimes the tv started and the sony logo appeared and the backlights went then turned off .i am trying to find out the codes on the driver board mean .The board is 100690311 .

Disconnecting the motherboard wire did not turn the leds on so i am guessing it is a power supply or led driver board fault .I havn't removed the screen yet to check the leds because it sometimes showed the logo before shutting down.

Does anyone have details of the flashing codes on the driver board to help me get this tv going again because i need to order parts from overseas .Thanks for your time .
