is this a hardware issue with TV tuner?

I had NextPVR working nicely for a week or two (I'm a new user, in the UK). I'm recording on my laptop and have an August DVB-210 tuner plugged into a USB port, which is connected via a nice new cable to our socket that connects to the aerial on the roof.

I discovered today that the last few programs that recorded had no proper picture. Lots of green, or mashed up pixels that didn't refresh. When going to the channel page that would normally show you what programs were on each channel right now, for watching live, some of the channels didn't show the current program names. I wondered if things weren't plugged in correctly anymore, but everything seemed OK.

I've now been on a fun few hours discovering that I could no longer watch live TV or record at all. Getting errors like Streaming failed (transcoder exited). I've uninstalled and reinstalled the August tuner drivers, and NextPVR, and had multiple blue screen of death reboots in amongst it.

I still can't view live TV. The scheduler faithfully tried to start recording several programs in amongst this, none of which were successful (obviously!). So I then decided to delete all the channels related to my tuner, and rescan. Several times I got a blue screen of death on clicking the button to scan for channels. When it didn't crash, I walked off for half an hour and came back, but it didn't find any channels.

What's the odds it's an issue with the TV tuner thing (or its drivers)? I'm not sure what to try next. I'm not sure my sister would let me try it out on her laptop.

I did attempt to copy and paste a url into the IPTV device (which was not set up at all previously) and got nowhere with it as I had no idea what I was doing. The url was from https://forums.nextpvr.com/showthread.php?tid=64944 . I've lost track of what went wrong first, but I'm 95% sure that the images stopped recording (or being received) correctly before I tried to get creative. I only have very recent logs to attach though.

That's usually a sign of the signal being too weak. ie, it's only receiving some of the data, so can't form complete pictures etc. It could potentially be a hardware or driver issue.

Maybe check the antenna is still on the wall and pointing where you expect.

That is sounding like driver or hardware issue. Probably worth contacting August and asking them for advice.
