T4000 Fault causing Power-Down ...

speedtrip — Sat, 12 Oct 2024 10:03:58 GMT

My veteran T4000 (2017) suddenly started Powering Off when the 'Jump Forward ' button on the Remote was pressed ...

I had a T4000 which we had never used from 2019 (bought for a 2nd Room) - so installed it and its new Power Supply ..

The fault recurred with this new Box Powering down on again using the 'Jump Forward' button - so thinking I had a problem with the original Remote Control, I swapped over to the new one supplied with the Box ....

... again the New T4000 Powered down when 'Jump Forward' was used ... the Box comes back up OK ...

It doesnt do this for the first couple of hours its on - then viewing a recording & using 'Jump Forward' it suddenly 'pops & cracks' as it Powers Down ...

Scratchng my head what would cause this - all old hardware replaced - the old T400 hadnt missed a beat in all those years ... clutching at Straws, wondering what else could have changed - a Box Update perhaps ...

Any thoughts appreciated !!

My T4000 works fine using your recipe, so not an update thing. Old age, maybe, or a random strike by cosmic rays.

I suggest your first step is a Maintenance Mode reset Option 2 (Keep Recordings) and see if that cures it:-

https://www.bt.com/help/tv/fix-a-problem/tv-boxes/how-do-i-reset-my-bt-tv-box-

Note that while this will keep your recordings, it will disrupt any recording going on at the time, so pick a moment when no recordings are happening or about to happen.

Also, it will put your settings back to the defaults, so make a note of any non-default values you have, so you can recreate them later.

Your list of scheduled programmes may also go AWOL, but these will return over the next couple of hours without needing any action on your part.

Choose the option for 4K Recordable TV Box, follow the instructions, and report back.

My point is that the same problem happened on the Veteran Box and the replacement unused one .... & the 'new one' would effectively have had a Maint Mode reset when it first powered on & set itself up ...

So I'm baffled as to why BOTH Boxes fail in this way ... - something changed just before the old one started failing - hence why I wondered if an Update was involved ..

Does it also do it if you skip back?

What about if you hold the FF down, which should perform the same function?

I guess you need to rule everything else out, unlikely as it may seem. So a different HDMI cable plugged into a different HDMI port on the TV. Then the AC adapter plugged into a different wall socket.

I've only had it power off when using the 'Jump Forward 1 Min' button - will try later if the 'Jump Back' button also does it ... mind you it doesnt happen for a while after being in use .. will also try holding down FF, but I think that just steps speed up from X2 to x30 ?

A different HDMI Port on the TV would negate the T4000 being able to receive UHD I think - but as you say a process of elimination is a good idea ...

My advice is don’t overthink it - just do the Maintenance Mode reset.

Do it on both boxes if both have the problem.

Do the house lights dim when the Jump button causes the YouView boxes to lose power?

A single press of FF will increase the steps as you say, but a long press should replicate the skip function. It's how my Logitech Harmony does both on the same key. Might take a bit of juggling to find the exact length of time the key needs to be held.

I don't understand the UHD point?

No, no impact on the House Power is visible, no clocks stop etc ....

Strange that the old Box ran for 7 years w/o the problem .... and suddenly its there & repeatable .... actually it had an MM Reset 3 or 4 months ago - and the new one effectively immediatly - but I will devote 15 mins to it & the subsequent setup chores for Hidden Channels & other prefs ...

Its too much of a coincidence that both T4000s manifest the same problem !

It depends on the trajectory of the cosmic ray……

Long Press - ah, OK, will try that.

On the setup booklet for the T4000 it stresses that the HDMI Cable must be connected to TV HDMI Port marked 'zero' (or summat like that) - to ensure UHD capabilty ... but I will try a new Cable ... and plug Power Lead into a different Wall Socket

Thanks for everybodies Help ..

Maybe a hangup from thee early days of UHD, when a TV might only have one UHD input. Bearing in mind the box is around 9 years old now. Unless your TV is of similar vintage, I doubt there's an issue.

It actually says you need to find an HDMI input that supports HDMI 2.0 and HDCP 2.2

It has no idea which, if any, inputs on your TV meet this standard, but suggests you ask the maker, or go to

https://www.bt.com/help/ultrahd

for assistance. Unfortunately, this no longer works. But most HDMI inputs on modern TVs will support this or better.

TV is a Samsung 2015 vintage & has an HDMI Socket Id'ed as HDMI 2.0 - as per the T4000 Booklet which you partially quoted ...

@speedtrip

It depends what you have the resolution of the YouView box set to.

If it’s set to UHD, it will always matter, even if the source material is at a lower resolution. If it’s set to a lower resolution, it will never matter.

I used to run my T4000 at 1080p, when there wasn’t much UHD around, as I judged my LG GX as slightly better at upscaling than the T4000. But now there is more UHD around, I run the T4000 at the highest resolution, and bypass the upscaling on the GX. Better a slight loss on 1080p than a massive one on UHD/1080p/UHD.

are the recordings you are viewing @speedtrip when the problem occurs finished recordings (ie the programme has ended broadcast or ) are you starting to watching a recording of a programme before the programme ends on the live channel ?

Re: T4000 Fault causing Power-Down ...

speedtrip — Sun, 13 Oct 2024 08:47:18 GMT

@zulu17 .. they were all 'completed' recordings (altho I have in the past 'chase viewed' currently recording progs, with no problem...)

I have been thru the list of eliminations, including a swap of HDMI TV Sockets & a Reset of the Box - the T4000 can still be persuaded to Power Down when 'Jump Foward ' is used - but not immediatly - & usually towards the end of a Recording ...

Any duration press of the FF Button just increments to X30 ...

Thanks for everyone's interest & help

Maybe it’s the remotes want resetting?

https://www.bt.com/help/tv/fix-a-problem/remote/which-remote-do-you-have/resetting-your-remote-control-1

The simplest explanation may be that the Jump Forward is sending a Power Off instead.

Or if that’s too simple, that the box is interpreting a Jump Forward as a Power Off. Especially if the box has to be on for an hour or two before this will happen.

Mind you, when two identical box/remotes exhibit an identical problem that I’ve never come across before, nothing is simple 😢

Re: T4000 Fault causing Power-Down ...

speedtrip — Sun, 13 Oct 2024 13:06:55 GMT

The Controller is the new one that came with the new T4000 .... so again we have identical problems with both T4000' and both Remotes ... it would seem - but I'm sure its something else ...

Re: T4000 Fault causing Power-Down ...

speedtrip — Fri, 25 Oct 2024 12:49:26 GMT

so an Update on the Power Down Saga for my two T4000's .... after a couple of Red Herrings like Standby time & a dubious SPIDF Cable (yep, clutching at Straws !) - I reported the failure to BT Service & they have sent a replacement Box -

..... to my surprise, its another T4000, not the new TV PRO box ....

So now we wait & see if I can use use 'Jump Forward' w/o the Box Powering down

Did EETV ask you to recontract, and you declined?

Getting a Box Pro seems to depend on being willing to recontract.
