This is a common TV repair with LED TVs. Normally caused by back-light failure. This is a repair carried out often in our workshop. Most recent makes with this problem would be: LG, Panasonic, Samsung and many cheaper branded TVs also.

Just wanted to say a big “thank you” to your company – and David – who sorted my Sony TV problem out this afternoon (2 December) on the phone. I was so appreciative of your advice and patience in getting my TV back up and running. Quality!
Cheers,
