I just hit what seems like a cross between the black screen bug and the Modern Family/Elementary bug. I was watching Mad Men on Netflix, Season 4 Episode 9 when it froze with a completely red screen (for a change) during the opening titles. I switched back to TV (which I had been watching a couple of minutes earlier) and there was the classic black screen - audio but no picture. First time round I was able to fix it by putting the V6 in and out of standby. I tried watching Mad Men on Netflix again, with exactly the same result - red screen in Netflix, then back to a black screen on TV. Incidentally, this time putting the V6 in and out of standby didn't fix it.
Absolutely. This is getting a bit silly. In the last few days I have had Netflix consistently failing on the V6 when it works perfectly using my TV's own app (with the V6 normal TV channels suffering from 'black screen' after the crash), catch up via iPlayer failing with (weirdly) a black screen with audio only, when once again the TV's own app works perfectly for the exact same programme, the 'standard' black screen bug after watching another source for a while (game console, Netflix on the TV, Netflix via the V6, Bluray player).
Sometimes putting the V6 in and out of standby works, sometimes removing and replacing the HDMI cable, sometimes a full reboot of everything is needed.
I have read various theories here: supposedly it's because the HDMI cable is going through an AV amp or similar - nope, mine uses a high quality HDMI 2.1 cable directly from the V6 to the TV HDMI socket. Alternatively it's the cable itself - well I've tried a variety and all work perfectly with every source - except the various V6 bugs remain. Then again it's the TV failing to complete the HDMI handshake properly, the V6 is a model of HDMI compliance. This last one crops up in a number of places and, although I have no idea how compliant the V6 is, I think it's rather high-handed to enter the market expecting a wide array of TV manufacturers to fall in line with Virginmedia and alter their hardware/firmware to work with the V6.
What does puzzle me is how in some cases the V6 can serve menu-graphics and sound via HDMI but not the video picture stream. I assume that at some point these components are combined into an HDMI stream and passed to the TV. I also assume that a successful handshake includes a confirmation of HDCP compliance and that if this fails, the menu and sound, which aren't subject to HDCP are allowed though, but the main picture stream isn't. Sounds like something that Virgin should be addressing, whether by talking to TV manufacturers or by addressing failings in their product, rather than expecting the customer to chase after Sony or LG or Panasonic or whoever.
It's easy to overstate this, because when the V6 box is good - it is good. Personally, now I wouldn't go back to my old Tivo box now; the slow response issues were just too much for me. But that's also what makes these glitches on the V6 so annoying. If there is a 'black box' involved then it's the Virginmedia response to problems. Never explain, never admit an issue, it's your television, it's your cable, it's your amp, there is no problem with the V6.
Humax, BT, Sky, Amazon: the list goes on. All these people make 4K video delivery boxes. It can be done.
