DVB-T Antenna and WIWA 90HD Tuner: Missing Channel Images Despite Strong Signal

Hey, the problem is this: I have a DVB-T antenna on the roof, which looks identical to MITON 1000 DVB-T (I don't remember if it's exactly this company, but it is DVB-T and it looks exactly like that). The signal from the antenna, through a splitter, is divided into two receivers - one LG 42LM640S (cable directly to the TV) and the other - the Wiwa 90HD tuner. Signal quality is amazing - both quality and strength are almost 100%. LG automatically searches and displays all currently broadcast terrestrial channels (including those of the subject). The problem occurs on Wiwo - the tuner finds the above channels but displays only their names but no image (info on the screen - no signal). Is the tuner a problem or am I doing something wrong? Thank you in advance for any suggestions.

You switched the output spliter (LG instead of wiwy)?

Well, I'll check right away.

EDIT: I checked - no effect. LG works as it worked, there is still no Metro, Zoom, Nowa and WP on Wiwie. Wiwa found them for me automatically on C038-C041 but as I wrote, there are only names and there is no image and description.

Mux 8 is broadcast on VHF, former channels 1-12 /, in addition in vertical polarization in some areas /. There should be an additional VHF antenna.

I corrected the post because an error has crept in - the decoder should tune in, but maybe it needs a better signal. For me nc + tunes Mux-8, and for a friend's four-year-old TV no longer.

good Seriously, I have an antenna in the center of G. Śląsk - is this a problem?

Well, but LG is tuning, so the antenna is probably OK. In addition, LG is older than Wiwy.

The antenna is not adapted to this band, in my instinct LG is better at dealing with errors, hence such differences (as long as there is no defect in the installation between the splitter and the wiwi decoder).
That it would be correct; second ant. on VHF + antenna crossover.

Thanks for the advice - I will keep trying.

Don't overdo it .

Search on manual, disable LCN and set sorting by ONID.

Maybe the cable between the decoder and the splitter introduces a lot of attenuation. Swap the decoder with LG, you will know if the signal is good where you connect the decoder.

Edit.
Read thread, read. Changing the outputs on the splitter is not the same as swapping the receivers, the cable can also introduce signal distortions. And one more thing: Maybe this Wiwa did not switch the band, on MUX 8 the band has 7Mhz, and on other MUXs 8Mhz (I have Wiwą 95 myself and sometimes when tuning I do not want to change automatically when receiving MUX 8 to 7Mhz).

Colleagues, I also had problems with 3 Wiwa HD90s. In the countryside, Mux 3 doesn't read me. I have a building location such that a very good signal is received from St. Cross but equally good from Dobromierz. And because they broadcast on the same channel 47, stupid Wiwa shows no signal. If you leave it for some time it can jump in and it is 100/100% and it can play for a very long time without changing the signal quality, but if it switches to a channel from another Mux and comes back to Mux3 again it is a cap. No signal again. There are no such eggs on new TV sets. Channels can be changed freely and nothing blocks. Set-top boxes were connected in places where TV sets were installed to exclude the influence of installation and it is the same. TVs are working properly, set-top boxes are not. I also have Ferguson, who behaves the same. In another forum there was also a discussion about these Wiwa and specialists came to the conclusion that it is a hardware fault and nothing will come up with here. After spending several dozen hours combining with antenna settings in all possible positions, I doubted and added one more antenna directed at Góra Kamieńsk and despite the relatively weak signal I receive a stable Mux 3 on channel 26, NTL Radomsko package on channel 36 with nice music channels and Mux 8 on channel 9 in polarization H from Dobromierz and I have peace of mind.

You have a choice of 2 outputs. Adding a second VHF antenna and crossover network, or dismantle the one you have and install a reticulated one, which is on the UHF and VHF bands. At my mum in Sosnowiec on the air you have, I don't catch Muxa8 and lives 10 km away from00 PLN and I in Dąbrowa on the net I catch everything.
