For some time now my TiVo V6 continually drops the tv signal (screen flickers black - no sound or picture).
It last for less than a second, but does this every 10 - 20 seconds, making it virtually impossible to watch anything.
Tried resetting, changing all connections, and even connecting different TV's.
Anything i do resolves temporarily ( 24 hrs at most).
Although I cant see why using a 4k spec HDMI lead would make any difference when the V6 isn't outputting 4k signal, and the tv attached to isn't isn't 4k compatible, I have actually tried that.
Ended resolving myself now. Basically, V6 cant seem to cope very well with just 2160p set in Video Out. But, selecting 2160p & 1080p together seems to have fixed the flicker issue.
Looks like the V6 box tries to auto-detect the right output format for the connected screen. Problem with that is, it doesn't do that good a job of it on it's own!!
