Re: DM 800HD se clone

Basing on my direct experience, 99% of problems are given by bad electrolytic capacitors.
Within this 99%, 90% are capacitors in psu unit, the rest in network section.
I don't think you will receive a good support from clone sellers, so you have to repair boxes by yourself (with a little skill in electronics and soldering),

As said gianni253, the most problems are in motherboard.
Faulty capacitors or other electronic parts on the m/b is the main cause for the broken clones.

The network stop working, the tuner don't work properly, the box can't power up... and many other problems.
The psu also have very serious problems and must be changed after 1-2 years.

All these parts need a special electronic who know about SMD circuits and fixes in order to be repaired.
In many cases the money that the repair costs is higher that a new clone, so these broken clones go for rubbish.
When a small fix is needed, this can be done easy by someone who know some things in electronic circuits.

In face of this reports is better give more money and buy another box with good support from sellers.

But if you tested it and it's working properly, the matter of replacing a capacitor when it goes bad won't be too difficult.

I agree mate: I've bought a bunch of low esr capacitors for few euros and when a power supply fails a can fix it in five minutes and 20 cents.

Yes mate, that is good for you
but not all people has the ability to fix circuits by it self or to find a good repairer with low cost.

Re: DM 800HD se clone

I bought DM 800HD se clone. Thanks all for your help.

There is something I'm worried about though:
When I check the memory using

cat /proc/meminfo

I get:

MemTotal:       137348 kB ...

Shouldn't it be 256 MB or I am missing something?

Can anyone who has it test this?

You are checking memory usage: the box is using 137 of 256, isn't it?

Re: DM 800HD se clone

Linux kernel only uses a part of all physical available ram.
The remaining is allocated at boot time for other purposes.
For instance, try "df -kh" and you will see memory allocated for tmpfs filesystem.

Re: DM 800HD se clone

in my opinion, if you cool dm clone all time long, there is a lifetime warranty for it (except thunders or you gige manually a short circuit)
I think it would be of more interest to discuss if a vu clone is better quality than dm clone and this is a difficult choise to do if you plan to buy a new box.

Re: DM 800HD se clone

Thanks Gianni!
That's a relief

I tried df -kh, and I got:

Filesystem                Size      Used Available Use% Mounted on
/dev/root                60.0M     47.1M     12.9M  79% /
tmpfs                    64.0K         0     64.0K   0% /media
tmpfs                    64.0K      4.0K     60.0K   6% /dev
/dev/sda1                 3.7G      2.1G      1.6G  57% /media/usb
tmpfs                    67.1M    584.0K     66.5M   1% /var/volatile

So is the total physical memory = (/dev/root) + (tempfs) + (MemTotal)?

Thanks aplok

Would you please test this too: cat /proc/meminfo

Sorry I'm not following. Please be clearer

Yes, more or less.

Re: DM 800HD se clone

the point is that overheat kill the boxes. if you cool your box enough thats gone be fine, thats what i mentioned. im doing it for now taking of dm fan and replacing it with external usb fan. its always cool and works great. you must pay attention in your home voltage to be good, and keep attention to bad weather if you conect your box with lan cause thunders may harm it

Re: DM 800HD se clone

Dear @igius12 , you are right

Overheating is the main cause of problems with the clones.

I would like to add that a very good movement is a buy of a ups or a power stabilizer or even a system with socket protection.
Not only for a clone, but generally for all receivers.

They, in many cases cost a lot of money and are very sensitive to power failure.
