DM800HD Continuous Boot Loop. Hardware Issue?

Good evening Ladies and Gents,

My DM800 decided it wanted to enter a continuous boot loop after it was unplugged directly from the mains.

I've tried everything I can think of, from flashing new images and bootloaders.

It never gets any errors and says flashing complete, via network/browser and also DreamUp.

That last thing of the screen before it switches itself off and reboots is "flash/vmlinux.gz"

Does anyone have any ideas on anything else I can try?

Or someone or a company that could repair it?

Thanks in advance for all and any replies.

Pinched from another site:

"Few likely cause i had personally experienced:

1) Try unplug the 12V power pin and wait for 5mins to replug, sometimes it work when onboard capacitor discharged, but most of the time, the ac/dc 12V adapter is faulty.

2) The image corrupted, just reflash.

3) Something prohibit the startup to continue, likely a device failed, perhaps tuner module not sitted properly, and failed to initialize, or HDD, or thumbdrive plug-in."

Tried all those, the box actually went a few weeks ago and I thought I'd give it another go today.

Remove any USB or HDD you have added m8 & try flashing again !!
If no joy try noCAerror repair tool in satdreamgr toolbox

What is the "DreamtroolboxGR"? I saw you post about it in another thread but can't find it.

You can find it here buddy: SatDreamGr Toolbox Dreambox Edition

But I have attached it for you....

Cheers mate.

Can't find anything in there though to help me :(

Think I'll try to find somewhere to send it to, see if it can be repaired. I can't think of anything other than a hardware issue, something must have gone when it got unplugged from the mains.

Thanks for the help guys.

run the noCAerror tool set as ssl84b worth trying m8
if successful then put into flash mode & flash the image of your choice?
Optiflasher is another great tool to fix this..

also try another PSU if u can?

good luck

I tried that with NCF-SIM2-2.5

Will try it again with the version in the tool box.

I've already tried different PSU's.

Not sure how to use Optiflasher. Do you have to put your own bootloaders in the folder directory? The only ones in there were numbered ssl 1-24. (I'll see if I can find a tut for it).

Won't try anything again tonight, my heads done in and the wife has got Home Land ready for us to watch. :)

I'll keep you's posted, however it turns out.

And thanks again to everyone trying to help. :thumb:

An update guys, and good news.

One of the capacitors had a bit of a bulging head. Changed that and it boots up fine now.

Here's a pic of the offending capacitor circled in red.

Hope this helps someone else out who happens to have the same problem.
