View Full Version : Deep Standby
I have a new Miracle Premium Twin HD with two terrestrial TV tuners for the UK Freeview service and fitted with an internal 1Tbyte hard drive. The box is running VIX Apollo build 030, Kernel 3/6/0, dated 7 September 2014
With approx 5 hours of playing around and going through all the set-up menus all things appear to work except 'deep standby'.
When the box is put into deep standby the blue LED on the front panel lights. When attempting to wake it up by pressing the power button on the remote one of two problems appear:
1) The front panel on the box continually displays 'Miraclebox' but fails to boot at all. It will remain in this state forever. The only way out of this failure is to turn the box off at the mains switch. The box will then boot up faultlessly on re-instating the mains power.
2) The box displays 'Miraclebox' then 'booting' and in the normal way, after a few splash screens, a TV picture appears BUT the hard disk is missing and the wired network connection is completely broken. When in this state pressing the restart option from the power menu will get the box working again.
This means that the box is somewhat useless as a PVR if placed in deep standby.
A quick Google suggests this is a common problem with these boxes but I haven't seen anyone report a fix.
Is there a fix?
That's odd, but you're the second poster with this issue. I have the same model since June and it's been faultless. Did you purchase from WoS?
Yes, purchased from world-of-satellite.co.uk and delivered Tues 9th Sep
Test 1
Internal hard disk connected, Wired network connected
Boot after deep standby results in hard disk missing, network connection broken
Test 2
Internal hard disk disconnected, Wired network connected
Boot after deep standby results in network connection broken
Test 3
External USB disk connected (no internal disk), Wired network connected
Boot after deep standby results in disk OK but network connection broken.
The problem seems to be 'internal' functionality and USB interface for disk is OK
Observation: If the box is in deep standby for less than 2 minutes it will not boot. The front panel will just say Miraclebox. If left in the deep standby state for more than 2 minutes the box will actually boot but both the hard disk and network faults will always occur.
When the network problem occurs the light is on the network port is endlessly flashing a very high rate. This doesn't happen on a successful boot that results in the hard disk and network working properly
Did you initialise your HDD with the receiver?
Have you left DHCP Enabled? Are you able to test connected to another router? Also try setting a static IP.
No its not a common issue, only 2 reports here. I've tested myself yesterday and could not replicate.
Tested again here this morning, all fine.
Do you have RS232 by anychance on a PC? Would be good to have a bootlog from your unit.
Some answers
The disk was formatted in the Micaclebox. I also tried the convert from Ext3 to Ext4 file format option from the menu. The box didn't complain about the disk. The fact that the disk seems to work flawlessly from booting from a mains switch on, from the 'light' standby and from a restart suggests that it's not a formatting issue. The disk fails to be seen after a deep standby. If it wasn't for the network also failing I may suspect a disk.
This morning I had a few hours to spare and have reformatted the disk (in the Miraclebox) and factory reset the box back to all its default settings. I then did the minimum to get a TV channel and a 5 minute recording. 99% of all menu items are still in their default sate. Putting the box into deep standby still produces the same hard disk and network fault.
Another factory reset back to default settings and the network set-up again and working. DHCP now turned off. After a deep standby the same problems. No hard disk , network broken – as indicated by no communication and the network test failing on IP address and nameserver. The correct values are still seen in the miracle box network configuration.
The hard disk format and network settings must be OK because the box subsequently works without problems after another mains on/off boot.
I haven't got another router to try but I swapped out the connection with another piece of working equipment. I have half a dozen other equipments connected to the router via cable or wi-fi and none give any problems. The miracle box doesn't give problems EXCEPT when waking from a deep standby.
I don't think the boot log is going to help except in establishing that I have a faulty box. (All faults are repeatable.)
A RS232 output during a power on boot reads in English and gives a working box.
A RS232 output during a deep standby boots reads in English and garbage.
It's looks as if at least 3 things are going very wrong after a deep standby.
I've also checked the boot log file with the internal disk disconnected and network cable disconnected. Power on boot gives an OK log file, deep standby boot gives a rubbish log file.
It's looks like a faulty box, possible a hardware fault in a power switching circuit that is ONLY used during deep standby.

The text output from the serial port during a "bad" boot looks like what you would get with parity errors. Maybe there is an issue with the power supply which manifests only during deep standby as you suspect?
Hi adm. I am having the same problem as you and have a thread running on this too at http://www.world-of-satellite.com/showthread.php?40362-Box-will-not-boot-from-deep-sleep.
I been in contact with WOS today and they have already a box coming back to there store at the moment with the same problems as we have got and they going to test it, and they will let me know on Tuesday of the outcome.
There is something weird going on in deep standby and make be Tony as a point here than the power supply may not be switching to full power to boost the box back to live.
Myself personally was thinking it was a bootloader issue, but now looking at your boot files I have seen these kind of results before when I use to build and program computers, and it all come down to a bad power supply.
So this may be something WOS could test and look into too.
I will keep you posted.
It may be my box they are referring to - its on the way back to WOS :(
It may just be power sequencing. I'm in the electronics industry as a designer and I've seen other examples where incorrect power sequencing can cause lock-up and unexpected behaviour. The power sequencing from a cold boot and a deep standby will be different.
I been testing my mirclebox this morning, working with the power supply. As Tony more or less knocked the nail on the head. and it more or less comes down to this.
These boxes must have a slow charge capacitor inside which is trickle charged with 1 Watt in deep sleep mode. The box seems to need a power boost of power to start the box up. If this capacitor is not fully charged when you remote on the box it just displays 'Miraclebox'
This capacitor seems to take about 10 to 15 mins to charge fully. if you boot your box close to the 10 mins it will start booting but with garbage output in the log file using rs232 and as adm states on is thread http://www.world-of-satellite.com/sh...559#post311559. the hdd and internet may not boot until complete power off using the rocker switch.
My box as to be in deep sleep for a Minimum of 15 minutes to boot with internal hdd and internet connection to boot successfully with no problems no fault codes in the rs232 log. which really deep sleep is only going to be used for overnight power down.
If this is what the problem is we have been all encountering, it would be nice if the User Manual would state this That Deep Sleep requires a Minimum of 15 minutes wait period before restarting. or the box may not function correctly.
Hope this helps as now I know what the cause was I now see no problem with my box.
Good stuff @Leader. I hadn't realised that the problem was manifesting itself only when in deep sleep for a short period. Seems likely that your suspicion of the capacitor might be correct and perhaps WoS will confirm in the case of @adm's box. I'm on a short holiday, so can't verify with my own model until mid next week. The only thing I noticed with my own box was when I was flashing new images from USB stick. After putting the box into deep sleep you are supposed to power off at the back and insert the USB stick and power on again. I found that I had to wait at least 20 seconds after powering off at the back (and that bright blue LED had extinguished!) before powering on again, otherwise it would not invoke the bootloader check of the SB stick. I had assumed from that behaviour that the reservoir capacitor was actually fully charged and it took that long to discharge. That blue LED is a major annoyance I find. I've had to put some black tape over it to dim the output.
This capacitor seems to take about 10 to 15 mins to charge fully. if you boot your box close to the 10 mins it will start booting but with garbage output in the log file using rs232
If true it may indicate that the power supply circuits are relying on capacitor leakage currents. Give the box a year or two and the capacitor leakage changes and the box will never boot from deep standby. It still suggests to me a fault, possibly during manufacture where a wrong value component has been fitted or a build quality issue (duff solder joint)
I could get the box to boot within 2 minutes (with a garbage boot log) and it made no difference if I left the box for longer than 10/15 minutes.
I assume that when others in this thread have said their boxes have no problem they are not waiting 15 minutes during testing. Can someone with a working box confirm that it comes out of deep standby within a short time or does it require to be in this mode for more than 10 minutes?
Although I didn't try it before I returned my box to WOS I'm assuming that the box comes out of standby to make a timer recording. If the timer happens to be within the long period that the box is in deep standby it will come out of standby in the faulty condition and fail to record as the disk is missing. Once in this fault condition what now puts it right? An on/off power sequence?
On another (unrelated) forum where a number of technically minded people are migrating to the Miraclebox family I have asked about the behaviour of their boxes after/during deep standby.
So far one reply with someone with the same box and same VIX image. From entering to exiting deep standby 1 minute - with no problems.

On testing my box this morning my box would not boot within the first five minutes.
I will try see if it will come out of deep sleep to do a recording test and let you know.
WOS will hopefully give you some answers to your box soon and please post back what the verdict is.
I just done the deep sleep record. It all worked well recorded the program of the sky scrambled channel no problem as long as I had the 15 min window.
So far one reply with someone with the same box and same VIX image. From entering to exiting deep standby 1 minute - with no problems.
A second reply - blue light on to exiting deep standby = 15 seconds and with internal hard disk and Ethernet working OK afterwards.
Then I may have a problem with my box if others are getting instant bootup. I will still be contacting WOS on Tuesday anyway to find out whats happening here.
Update but not a lot to report.
Box returned to WOS (after getting a return number) and was received by them Monday morning
Box expected back tomorrow (Wednesday) with a replacement power supply board.
WOS sent 3 emails, acknowledged receipt of box, said they were testing it and a tracking number for return.
If I get the box back as expected I'll report on the operation of Deep Standby tomorrow evening
Hope all working well once on its return,
I got a reply back of Miraclebox and they are saying its a driver fault and should be sorted in the new bootloader release coming shortly. Mind still won't boot within 10 minutes so see what your's is like once you get it back. Thanks for keeping us informed.
My MiracleBox Premium Twin HD won't boot after 20 minutes of deep sleep. Booting always succeeds after 60 minutes of deep sleep. I have not tried any values in between.
Leader: please tell us whom you have contacted at Miraclebox and what exactly have they said concerning the driver / bootloader fix? How soon can we expect this fix and where
will it be available for downloading?
Is it plausible that this would be a software issue after all and not a hardware issue?
My box is back from WOS
It's still faulty. Nothing has changed! Obviously they haven't tested the so called repair (a claimed change of power supply).
I haven't bothered opening up the box to fit a hard disk but the boot log is still corrupted and the Network connection broken.
I have already confirmed that the behaviour of my box with regard Deep Standby is completely different to that of others, one of which was delivered in the same week with the same VIX image.
Less than 2 minutes in deep standby and the box will not boot at all
30 minutes in deep standby and the box will boot with a corrupt boot log and a broken network connection
Is it plausible that this would be a software issue after all and not a hardware issue?
If its a software issue why do two boxes of the same specification running the same VIX image and delivered within days of each other (my box and that of a fellow contributer to another forum) behave so differently coming out of deep standby? My box has faulty behaviour, his box works as I would expect by coming out of deep standby correctly after 1 minute.
I've just had a phone call from WOS
They saw the non-booting/standby on my box when they first tested it.
After a replacement PSU the fault went away.
On return back to me the same fault - so possibly an intermittent fault/loose or faulty connection.
The box is on its way back to WOS this sfternoon
I think its a bit of both software and hardware, but just can't put a finger on it. the message I got of Miraclebox was short and sweet as they didn't reply to my first email I sent them a bit more of a pushy one which they replied too. here's a copy of it.
A bit of a weird company they have No contact tel number or address anywhere, looked all over the web can't find nothing.
Dear Chris,
Thank you for the mail. It seems to be an issue with the drivers that is hopefully solved. Please just await the newer softwares and it will work.
Thanks.
Med vänlig hälsning/Best regards,
Supporten Miraclebox
Like I said short and sweet.
Am not convinced its a software fault. if it was it would be happening to more boxes and it would follow the same routine. it to varied so it must be hardware. maybe faulty parts bad batch. looking in the boxes there only 2 main boards. so there not that much fault finding needed really.
Just back from holidays :(
Anyway, tested my MB Twin this morning. Put it into deep standby, drive spins down, video image off and blue LED illuminates. Pressed power button on remote control immediately and box reboots fine. No issue whatsoever with start up from deep standby irrespective of duration. Box was recording various programmes every day over the week I was away and going into and out of deep standby each time. No recordings missed. I'm on the standard ViX release 030 and have whatever bootloader was in the box when supplied. I've never seen a download link for the MB Twin bootloader in any case.
I can only think that there is a component fault in the PSU of affected boxes.
I can only think that there is a component fault in the PSU of affected boxes.
My one has had 2 PSUs - same fault with both.
It must be a hardware fault then, we are all on the same bootloader, The Vix image shouldn't make much difference from image numbers. I think I was on 030 or 032 when I did the test. and as Tony as said his boots straight away there maybe something different on manufacture or just bad parts. The thing is if it was a PSU it would still reacted the same way from a full power off or deep sleep, if a psu is not producing enough watts then it wouldn't boot from a fresh start either. it could be a dicky capacitor or something. But has the box is still under 2yr guarantee then we can only deal with it by sending then back for repair or replacement.
Update: 26th Sep 14
WOS replaced the box with another unit. I have it on for around half an hour (with a minimal setup/configure) and deep standby on this box appears to be working. I can switch the box into deep standby and switch it back on 30 seconds after the blue LED comes on with it booting without problems - and with the hard disk and network working.
I would suggest a box that requires it to be in deep standby for 10+ minutes before it will correctly start up again is faulty.
