Red LED flash 6 times, no startup
I have a Sony Bravia KDL-55NX723, red LED flash 6 times and does not startup.
I have taken apart the rear and started troubleshooting this matter.
I found a guide to error codes on bravia TV's and it states : Backlight issue, bad main board, power board or inverter board.
I have checked the 3.3 standby Voltage, this is present.
The 12 V regulated DC from main PSU to second PSU (Inverter board for LED light??) falls to 0 V when TV is turned on and red LED blink.
By removing different cables i can make the TV display different error codes.
1: removing video cable it blinks 5 times. (Bad lcd panel connection)
2: removing what i think is the tuner, it blinks 10 times.
This gives me hope that maybe the main board is still OK, since it tries to start/locate this and then gives error code when is discovers a problem.
When removing the cabel im pointing at, the green LED starts and stays on for 5-6 seconds, then it cannot start and red LED error is shown.
Any ideas as to what is it? Could it be one of the two power boards?
