YouView box problem
Hi
My BT YouView box won’t start up.
Powering up from the DC on switch red light comes on the left of the box
pressing on button on the remote control the BT waking up logo appears on the screen together with the red light changing to blue and in the lower left of the screen the letters UKTFAA 0.05 appears
No further progress to the second blue light on the right side appears. IT stays like this eventually screen goes blank blue light goes back to red and then a few seconds later goes to blue and BT waking up appears again It seems to be lock in the reporting wake up mode
No hand set or set top button panel can get passed this
checked the 12V supply all seems ok at +12V output
checked the lead to the BT hub all seems OK. Also bypassed the the lead to the `bt bub with a spare one and again no effect.
the box is a DTR-T2110 obtained in October 2015
any ideas ????

Or if that does not work, as it might not, Option 5 is a Factory Reset. If the box comes back from that OK, it will be as if it had just been delivered. But better back working than not working at all.
If Option 5 does not work, there is little more you can do. If you had a suitable disc drive handy, you could try swapping that in - installed with any existing partitions wiped off the disc, the box will do all the reconfiguration necessary - but you could probably get another box off eBay, or from CeX, for about the same money as buying one.
I followed the steps for a DTR-T2110 Maintenance mode. First 2 steps it responded as the instructions said but instead of offering the maintenance mode option it just stays locked in the BT wake up screen and then keeps trying this as before. No maintenance options appear and on screen instructions.
I thinking its had it!! But I have repaired other electronic devices where the capacitors have failed this very common in domestic electronics. Wonder if that is the possibility. have measured the current consumption on the +12V DC input and it is around 500mA and seems pretty steady
Thanks for your help anyway but if you have any suggestions would be happy to hear them
Sorry that didn’t work out.
Worth a poke about though, if you have experience diagnosing and replacing bad caps.
Do please let us know how you get on!
Thanks for all the good suggestions . I have replaced all the electrolytic capacitors in the unit
and it still exactly the same fault. So iy looks like it is shot so will get a replacement
Thanks again

Is the programme for the box operating on the disc drive or is it in some of the memory chips? another way to put it is the disc drive only used for recording?
thanks in advance for any info

You want I should take lids off? 😛
This tells us, I think, that each new software release installed must be downloaded to volatile storage, and then copied to non-volatile storage, overwriting the previous release only after the download has been checked and found OK, in a place on the box other than the disc.
I suspect though, that the downloaded copy of the release is kept on the disc drive, or maybe reloaded there from the NV storage, ready to be loaded into RAM when the box is started from an unpowered state. This is because it takes longer to start a box in this state than just to take one out of standby, where the copy in RAM is presumably still sitting there.
I think there is a disc copy of the software involved throughout, and not just for the initial download, because of the difference between a soft reset (clear all RAM and start up again) and an Option 2 Maintenance Mode reset, where my understanding is that a copy of the operating software is refreshed from the copy in non-volatile storage, so what is being refreshed is a non-volatile, but potentially corruptible, copy of the software, which I would imagine lives on the disc, rather than anywhere else.
You can take the disc out of a YouView box, though, hook it up to a PC/laptop running Linux, or even one just booted off a distro, and examine its partition structure, and what’s in them. Provided you don’t write to the disc, you can pop it back into the YouView box afterwards, and it will carry on as usual.
This is because a YouView box can recognise a disc it has made, and won’t reformat it, as it would with a foreign disc you mounted. How the box recognises its own is of course a well-kept secret 😛
Corrections and additions to this exegesis, from within YouView or without, are welcomed.
