[marekk]

Hi,

I would really appreciate any help to find out fault with this TV.
I bought main av board form very similar TV 40NX711 and it did power up, but after half an hour it shuts down and again led blinks 4 times.
Many thanks in advance

I have a KDL-40NX711 (4 blinks is the balancer)

See my similar thread about 6 blinks due to a burnt out LED.

I now have 2 working LED Driver Boards, let me know if that is your issue.

Unfortunately I don't know how to verify whether it is faulty LED driver or one of the LED in the backlight.

if you swap the driver board and it still has issues that should solve it.

I can send you one of my extra driver boards. I paid $10usd. I am in London on July 10th and could post it from there.
