Over the last couple of months, the latest being last night, my V6 box has displayed a grainy or noisy picture on all channels. Reminiscent of a low gain tuner or aerial fault in the old days.This has happened around eight times. Shows up particularly badly on dark or black backgrounds. I have a Tivo box which is fine. I have discovered that carrying out a reset on the box cures the problem each time. I'm assuming theres an intermittent fault in the box. Any ideas anyone and if the answer is a replacement box how would I get one? Gave up on the phones after half an hour on hold.
