This has got to a point where box is going to hurled out if the window!

The screen has been dropping to black with no audio briefly for a while now. Lately, it's extremely frequent and very annoying. More worrying now, there seems to be some electrical "zapping" happening. This is both an audible and a visual small line on screen.
I've tested other cables, have dusted the leads (although pretty clean anyway) tried rebooting and so forth.
My tv is a relatively new model, is a 4K Samsung Model Code: UE50MU6120. No other device does this on the TV except the TiVo.
It's taken almost 1.5 hours to watch a recorded 45 minute show (take out ads by fast forward!) From having to rewind what I'm missing during blackouts!
After reading other posts, worth noting the blackouts occur whether in the menus or just watching live TV/recordings.
I tried changing settings on display, turning off 1080p and so on but to no avail.
Box may need replacing. TV too if that zapping gets serious!
Cannot contact VM on phone no land line handset and not paying their ludricus "from other phone rates"
I've purchased a new cable since first post, turned box off on mains while out getting said cable and is exactly the same, if not worse!
