Snowy screen then freezes (4k UHD)

[Jodyyoung]

Having the above happen intermittently then gets predominantly quicker in between each snowy screen and then the box totally freezes and is unresponsive. 

I started having the same issue with the previous gen box and BT sent me the 4K UHD box to try and solve. I've changed my HDMI lead out incase that was on it's way out, but still does it. I even selected the signal strength option to monitor if it was related to my aerial, nope, all good there 100%. Out of ideas really until I get in touch with BT again. Have never had issues with boxes all the years I've had them.

Please clarify if this is the DTR-T4000 or the Pro box.

If the former, get BT to swap you in a Pro box.

If the latter, try a soft reset; hold the BT button on the front for just over 8 seconds and the box will perform a soft reboot.

if this does not improve things, try a Factory Reset (Keep recordings) by resetting via the buttons, not the Settings option:-

Hi @Midnight_Voice thanks for replying.

It's the DTR - T4000 box. So shall I try and get BT to swap out to a Pro? Do a reboot also?

Thanks

@Jodyyoung 

Yes, the 8-second reboot is the same, and the T4000 uses the rather better explicit Maintenance Mode Options arrangement that YouView boxes before the Pro box had, but just choose your box from the same link I gave above.

Something to do while waiting for the (on paper) theoretically better Pro box, anyway.

Hi @Jodyyoung 

How frequently is this occurring with the present  box ?  Is there any indication  that the box is getting  very hot  ?

When it freezes is it just the current  live channel or the whole box . Ie. It you press the home button  on the remote does the home menu get displayed. ?

[Jodyyoung]

Hi. Yes the box gets very hot. The whole box freezes and is totally unresponsive via remote when that happens until I obviously reboot it, so no, I can't access on the menu etc. Thanks

Thanks for the info @Jodyyoung .

is the the box itself reasonably well ventilated or is it for stacked up on or with other devices.

[Jodyyoung]

Yes all well ventilated, fan outlet not restricted at all and not stacked on any other device.

Does the fan seem to be working  if so does it seem to be working continuously and does it sound noisy ?

[Jodyyoung]

Yes you can definitely hear the fan continuously and when it has a wobble the fan kicks in on max speed!
