Hello!!

I installed a Hauppauge WinTV-HVR-955Q tuner on my Edision OS mio 4k+ an it was working without any issue until now. Now from time to time when I switch on the receiver or after I watch any recorded TV program (Tuner "C") and go back to the satellite channels, I get the message "Tune failed" (Letter "A" is yellow and not green) and I have to reboot the receiver to get it back on track.

 

I tried that yesterday changing the option of preferred tuner. The preferred tuner was "C", this is the TV tuner, then I changed it to "A" (satellite), and it seems that this change solved the problem. I turn off the receiver several times, change from A tuner to C tuner, etc.. and worked fine until today that the same problem happened. The tuner was switched off for several hours.

When I press OK on the remote control to get the info of the current satellite channel ,the "A" letter appears in yellow, while the "C" letter is green when I select a TV channel. It seems that the receiver get stuck on "C" tuner and is not capable to change back to the "A" tuner.

Any recommendation to solve this issue?

I'm running OpenPli last image.

Hi
 What is "OpenPli last image" supposed to be?
 Images have numbers. It helps to know what Image is actually loaded in the receiver (Menu--->Information--->About).

 In general, the problem you describe could probably be traced to bad cabling or improper receiver settings.

Hi

 

The OpenPli version is the 8.3. Bad cabling? I think if it were bad cabling the problem will continue after rebooting. When I mean rebooting is the complete receiver, not the rebooting of the image. Doing this last one, the problem is not solved at all.

What are the receiver setting that I have to check?

Let's see. What have you told about the physical connections of your receiver so far? Nothing really. Obviously you have something hooked into tuner A or you would not be using Tuner A. It might help to describe in detail the cabling, switches, or anything else that is connected to tuner A.

Then there is tuner C. How is the usb ATSC tuner connected to the receiver? Is it plugged directly into the receiver? Are you using a short extension cable or usb hub?  How is tuner C connected to the terrestrial antenna? Preamps, Splitters, Amplifiers, Ground blocks...etc.

Tuner A: 4 lnbs connected to a 8 x1 diseqc switch (Capable of 8 LNBs). Each LNB (satellite) is configured as Universal, Voltage mode: Polarization, Tone mode: Band, Diseqc mode: 1.0, Diseqc q.0 command: A, B, C, D (each letter assigned to each lnb.

 

Tuner C: Antenna, 4 way splitter (4 TVs), cable connected directly from the splitter to the Hauppauge 950Q , and this last one connected directly to the USB port of the receiver (back usb port).

 

Note: The same configuration is working perfectly on TNAP 4.1.

It would be a good idea to compare the settings file of both images (the one that works and the one that has problems) and make sure they are EXACTLY Identical. There are programs available for file comparisons that show the differences.
 

Another thing you can do is split the systems which are terrestrial and satellite. Delete either terrestrial channels or satellite channels and verify that everything works properly, then install the other system and check it. In other words, try just satellite or terrestrial services individually and verify each group is working correctly.
 

Anything is possible, but there is not much in the image build that would cause the problem you describe.  Supported Hauppauge ATSC usb tuners have been working for some years in various distros including OpenPLi, so it is doubtful the image or the particular OpenPli build is the problem. The settings file located in /etc/enigma2 of receiver files may be different in one of the two images. Check this very carefully as they should be identical except for maybe a skin name or something similar.

You also have a ton of cabling in your system, with various switches,splitters, lnbs...etc. Bad cabling is notorious for causing the issue you have described. A little bit of sweat or moisture inside a cable connector can cause your issue. A moisture problem in the cabling may be seen on some days and not others, depending on humidity.  Several other things could cause the issue you describe too, but cabling and settings would probably be the most common.

Also check and make very certain, 1000% certain the problem is not really in both images because you  will have a terrible time finding the problem if you think one of the two images is working correctly when in reality it is not!
