Sony Bravia LCD TV - faint patterns regularly track right to left across the screen. Sometimes small vertical bars, sometimes 000 with the word 'digital' below. It's not a huge problem but a bit irritating and I'd like to know what's causing it and if there's anything I can do about it.
Interesting.
Is this a new set? If it is you might want to take this into a service center for repair. This may need nothing more than a firmware upgrade.
