Youview humax box freezing with black screen while playing recorded programs

While watching a recorded program youview decides to freeze with a black screen.

This has only started the past 4 days and does this regularly. Once frozen it stops playing and presents a back screen, the remote ceases to work and you cannot turn it off on the front.

The only way to reset the box is to turn it off at the back. Once turned back on at the back and then turned on at the front the box boots up and takes ages, like it's the first time it's ever booted.

You go back to your program and it has not remembered where it stopped and starts from the beginning. You then watch it again and after 5-10 mins it crashes again and the previous steps mentioned have to be repeated, again with it not remembering where you last finished watching.

This has happened while watching TV programs once but its constantly happening during playback in the MyTV section.

I have noticed when I turn it on from the back it has a little square text box saying full on the display. I have 28% free space so I don't know what that's about!

I have checked updates and my box and apps are all up-to-date and was last checked as reported on the system information on 29th Apr 2017.

Some help would be appreciated and am wondering if others are having his problem.

I have recordings so will a factory reset sort this but retain my recordings.

Regards.
Paul.

    Hi Paul - from your description I would speculate you may have an Humax T1000 YouView box. There original boxes are well know for developing hardware faults, potentially linked to poor quality capacitors inside the box. Your issue may relate to overheating or a failing hard disk.

    For some info and links about various issues that arise with the older T1000 boxes see this old post.

    Note the factory reset option will wipe all your settings and recordings so that is very much a last resort. There are other resets, known as maintenance mode resets, that are less drastic. One should start with MM2 or MM4.

    The FULL on the front display refers to the resolution, i.e. Full HD, rather than any reference to disk space.

    Good to look back at your post, I hadn't seen it before. Good to know I'm not the only 'tinkerer' :~)
    It does seem that when the hard drive reaches about three quarters full things start going a bit haywire. I think this is down to disk fragmentation, which is something the developers of PVRs have never considered. On a couple I've repaired in the past disk fragmentation was over 90%, and on one of them, although still apparently 30% empty, the space was scattered in such small packets the disk was, for all practical purposes, full. Sadly, you can't just whip them out and defrag them with standard windows software - you need a specialist setup for dealing with odd formats. I tried reformatting both these drives, the first was a complete success, the second a total disaster and lost everything! The only way of sorting out a badly fragmented drive using 'normal means' is a complete reset, losing all recordings.
    The capacitor problem only affects the 12 volt rail, which powers the hard drive motor and a few bits like the fan. The box will stick in 'nearly ready' mode until the hard drive is receiving a stable voltage to drive it at a constant speed, and as the capacitors get older the voltage tends to fluctuate. If you want to revive a dead box, but are not confident with a soldering iron, one solution is to replace the drive with a 2.5 inch SATA drive which uses the 5 volt rail to power the motor. The 5 volt supply is much more reliable and has capacity to spare to run the drive, and the whole machine will run cooler and use less power. The fan will happily continue to work properly as it can cope with slightly wobbly voltage!

    Thanks for your help guys. Will have a look at the links and check which box version I am on.

    I actually meant defragging, not reformatting, silly me......... :~)

    If you take the hard disc out you can use Spinrite to fix any problems including bad sectors so also defrags.
