KDL-55NX720 turning itself off

[colinwyatt]

My Sony Bravia KDL-55NX720 will turn on for about 5 minutes then turns off. I am getting an error code that flashes 4 times. It has been doing this for about 6 months now, please help.

Hi Colin, 

It might be worth performing a factory data reset on your KDL-55NX720. Do let us know how you get on. 

Thanks,
