Nie, dziękuję Przekieruj mnie tamkolys wrote:If there is no picture but it plays sound and EPG, it means that the TV set has a newer T2 head but the processor or software cannot decode HEVC video. For some of these TVs, the manufacturer has created software updates that add support for HEVC decoding, so it's worth checking and updating. If there is no image on the latest software, it remains to buy a decoder or replace the TV. The solution could also be a CI module that converts HEVC video to MPEG4. Unfortunately, it seems that nobody came up with the idea to produce such modules and put them on sale. In the past, you could buy a CI module that converts MPEG4 video to MPEG2 because many TV sets only supported MPEG2 and in Poland only MPEG4 worked.

Nothing new in this topic?
I was thinking about uploading a different software from another PANASONIC TV
TVs from 2014 do not support HEVC, but I found a model from 2014 TX-55AX900E which HEVC has and from 2015 TX-43CX750E also has, these are 4K TVs, and mine found HEVC but there is only the sound of the image, the 2014 model TX-47AS750E and such versions of the software and such processors are given below.
Visually identical softs in terms of functions and operation, but I am afraid if it is possible and how to restore the old soft in case of failure, I have nothing to test, other motherboards, only one TV and there is no description anywhere and whether it would be able to do it to do this?
TX-47AS750E Dual-Core Plus 2014 P145_3114.zip MY TV
TX-55AX900E Quad-Core Pro5 2014 P146_3054_G102.zip
TX-43CX750E Quad-Core Pro 2015 P153_3252_N025.zip
Of course, they are packed, and the soft version is SDDL.SEC, what to unpack and see what's there?
There is a difference in processors, but my old single-core IBM T43 laptop on Linux HEVC plays, so I figured,
TX-47AS750E Dual-Core Plus would also play?
I thought about removing the codec from TX-55AX900E Quad-Core Pro5 2014r P146_3054_G102.zip and adding it to
TX-47AS750E Dual-Core Plus 2014 P145_3114.zip, is it in any way possible?
Any suggestions, gentlemen or total linden?

TL;DR: 95 % of Polish TVs sold before 2016 cannot decode DVB-T2/HEVC [UKE, 2021]; “No CI+ card can add DVB-T2” [Elektroda, tomaszlonski, post #20113681] Re-scanning or firmware tweaks help a minority, but most owners need an external set-top box. Why it matters: Missing broadcasts can look like a broken TV but stem from codec and modulation limits, not reception faults.
