Yes, I did. Blue colored cable disconnected.
Also checked with connected and disconnected power cable to main board.
Still same.
You my only hope, what's next step, please

Is your TV 50pb690v?
Or 50pb550b?

50pb690v

I'd suggest using the thread you created as your TV is 1080p and this is 720p.

It's a similar layout to this TV however there are many differences.

It's confusing for other folk looking in.

Anyway I've asked you a question in your other thread.

Thanks a lot for your support.
z-bias = 66-67V
vy = 0, cant find test point for vsc on Y-sus board.

I'm just not sure if there is a problem with Y-sus or Z-sus.
With disconnected Y-sus or both (Y-sus and Z-sus) still no signs of life, no standby, no reaction on remote etc...
