The problem DVR does not start!

Good evening, I write this text with Google Translate so I apologize if there are mistakes.

I have a DVR with 4 channels of analog producer AKU MODEL AK-2204 SYSTEM PAL / NTSC POWER: 12V DC

S / N: 201412100237

DVR starts with the logo image appears and remains stuck at initializing system I left a whole day and if I give nothing and no restart is not working.

I changed the CMOS battery and had no effect.

What can this DVR?

It can rewrite the firmware from it?

I found no support even the site from the maker aku.

In its menu Dahua wrote the software, I repeat it has no HDD installed to generate this problem.

I'm waiting for your answer. Thank you.

try installing a hard drive.

Until now there had installed a Hard Disk place but I think that will take effect if you install one now.

I think it is a problem of the system of scalding no longer charging.

Try changing the hard drive. This normally happens when hard drive is dead.

It does not have a hard drive installed in the machine

It does not have a hard drive installed in the machine

That could be the problem. It may need a hard drive installed in order to work.

And if you think you install a hard disk will eventually start ?

I can't be sure about it.

But that's one way you can troubleshoot.
