Hello,

 

I have 7020Hd equipped with  2.1 software. After upgrade over menu, it did not show any picture on FTA channels. Interesting is a fact, that EPG and signal strength had indication. Screen is just black. I got error message I-Pat not found in list or something similar.
When I upload DM origin sofware 3.2, it has from processor 87, the it works fine, it will find all channels. After upgrade to OpenPLi-3.0-beta-dm7020hd-20130927 no channels found. Set up of tuners are done. Any good idea, how to fix it?

 

Thank you in advance,

i70

Sorry, I have to give a fix, no picture on any channels, included FTA.

[indrek70]

The correct fault message at screen is: No data on transponder! (timeout reading PAT).

 

The SNR is OK, EPG is OK.

[Erik Slagter]

That means no data is entering the SoC. One of the causes is a faulty security chip, which causes the drivers not to fully initialise. This can be seen in the dmesg output right after booting.

 

I'd advice flashing a current DMM release image, check if the problem persists, and file a bug or defect if it does.

 

It's not somehing OpenPLi-related anyway.

Dear Erik, thank you for your feedback. I have already tested the DMM original image release-dm7020hd-3.2.4. No problems with channels searching and displaying on screen of my TV.

I did not told, why I made upgrade of current PLI software. After switching to fifth or sixth channel, I lost picture. I still had on screen info about signal level, EPG and external connection IP. Then I made the full restart and I had again picture on the screen of my TV, until I made some channel switches, after what everything became same. Only restart helped. After some weeks it did not help and I decided to upgrade from my current OpenPLi-3.0-beta-dm7020hd-20121222 to latest. I did it over menu software management - software upgrade, do not remember so well the name of menu.
Now, I have no idea, how to fix it.

Thank you in advance,

Here is another guy who cannot find any channels:

I know this has perhaps other reasons, but in another forum there's also a user who cannot find any channels (Astra 19,2).

[Erik Slagter]

It seems there is a bad interaction between the driver and CCcam 2.3.0, you might want to try an old version of CCcam.

[indrek70]

Dear Erik, thank you for your posts. I am using the mgcamd 1.35, but how are involved between each other zero channels at channel search and bad interface between cam and software? My problem in this, that I can not find any channels by channel search and if I am using old backup, then after switching channels, it does not clear the picture and does not show picture at FTA channels ...
Now I am guessing, how to go on? Should I clean some way the flash?

 

Thank you in advance,

i70

[Erik Slagter]

Yes you're right, I mixed up your problems with another common problem on the dm7020hd.

 

So there are two issues, you can't find any channels, and they don't descrambled. 

 

Obviously the first needs to be addressed first. How about using the satellite finder (menu->service searching->satellite finder) and try to get a lock on at least one known working transponder?

[indrek70]

Satellite finder is able to lock all channels, I am able receive at the north of Estonia.

I had with first motherplate flash the problem, were I found some bad sectors. I am going to use now dream-up to test flash. Maybe there are some sectors, which are bad? Could it be that none working line of image, which is involved into channel search is located on this sector and DMM original image has same line at different address. This also could explain, why DMM origin is able to find channels.

 

Thank you in advance,

[Erik Slagter]

What do you exactly mean by "channel search" then, if that's gives zero channels?

[indrek70]

After installing latest image, I did not used any restore function. I described all my 8 LNB-s, terrestrial tuner with Europe DVB-T set-up and I started the channel search. I have used all different options, one frequency on all of my satellites, all satellites, all, DVB-T separate, always the result is found 0 channels.

If I should have any problem with Diseq (10 inputs), then at least DVB-T should give found channels.

 

Thank you in advance,

i70

[Erik Slagter]

If you can find all transponders on all lnb's using the satellite finder, then there is no hardware issue.

[indrek70]

As I said, there was warranty issue at my origin flash and motherplate was replaced this summer by the official dealer of DMM.

[indrek70]

What do you think about bad sector(s) issue?

[Erik Slagter]

Unlikely. NAND flash always has bad sectors.

[indrek70]

Then I have to find first an answer to issue from what everything begun: I was looking to one provider channel, switched to an other channel of this provider and it could not be descrambled (not issue with favourite or ignore list). After it all other channels at other satellites went also dark, no picture even at FTA channels, only sat finder was able to lock what ever transponder. I did full restart and first month it helps. At one day no more help from it also.

Strange, I have not found anything like this. Could it be, that some provider has in data stream something, which could damage something?

 

Thank you in advance,

i70

[Erik Slagter]

I guess you already tried restarting?

[indrek70]

Yes, restarting, factory defaults, and restore settings are all been used.

[indrek70]

Thank you Erik for you time and support. Conclusion is following: something should be wrong with hardware, because DMM 3.2.4 work very well, but 4.0.0 is crashing. I will give it back for warranty, lets see what they will say.

 

BR,
