I have problems when turn on, signal not found, it should be good signal, I don't know what I do.

Can you give us more information, what satellite, transponder, channel.
What message is on tv screen, does the receiver power up, are you using SCART or HDMI.

Den

Any satellite, any transponder, is like wire cutted, signal=0, quality=0, when I put between other receptor in stand by, I can watch, It have sigal.

Message is "no signal", I use HDMI.

is it the tv that does not detect the HDMI or the decorder does not lock signal of the channel, please elaborate further.

I can to enter to all menus although put "moving motor" do not nothing.

Is your system a fixed dish or a motorised, have you checked all connections etc.

Understanding the SIGNAL and QUALITY readings on the antenna display page of your receiver:
(a) S=0 Q=0.....no lnb connected or bad coax or bad lnb
(b) S=70 Q=0.....lnb connected no signal from satellite (the 70 is noise generated by the lnb)
(c) S=70 Q=70.....lnb connected, signal from satellite OK, adjust for max Q.

I have motorised dish, with other reciver all satellites works ok, lnb and motor is conected ok, the wire is 25 meters aprox, when I put a wire of 10 meters all works ok. When I bougth the reciver, some days works ok, but now never works.

Have you got a spare power supply of the same amp, to try

I don't understand you, I have only two recivers, gtmedia and mvision, one motor and one dish. When I connect the reciver like bridge in stand by, I have signal in gtmedia, but I don't want use mvision.

Do you speak spanish?

Look this.

The 22mtr cable that you have (there must be a short some were (for the MVISION receiver is (amplifying the signal) with you using it as a loop-through)
So with a cable of a short length direct to the V8x from the motor everything works.
Which points to 22mtr cable needs to be looked at, check connectors etc, ( for a trial try a new cable of the length required (just lay it loose from the motor to the V8x)(that is if the other half will let you run cables all over the place) and see what results you get.

Good Luck

I can replace the wire but I don't know if solve this problem because I think the wire is too long. The first days when I bought it, sometimes I had a signal with the long wire, but now never.

The length should not matter, just try it, and see what results you get.
I have a V8x, my cable run is more than 22mts, with 100cm dish my readings on transponder 12548v 29600 is S93% Q77% I am based in the west midlands uk.

Good Luck

I do not know if it will be due to the length or because when passing it through the roof, it bent several times.

Thanks.

From what you say, the cable may have been in place for a while, so I would think it would be best to replace it and get a few more years service, as you know cable does perish over time.

The wire is new, two months approx., 3 months ago, I bought the first reciver gtmedia in amazon, the same happened, sometimes had signal sometimes no signal and while recording appears in tv "usb error", I returned to amazon, and after I bougth the same reciver in aliexpress.

I have this too.
It is something is the software.

I will do some tests today and report here and to GT Media.
I wonder if it is the unit does not send DiSEqC commands on power up? If so then any channel on DiSEqC switch port 1 should start after power on.

DiSEqc1.2 function you use
1. Under the satellite list, switch to rotate the satellite antenna,
2. Under the program playback, switch satellite DiSEqc1.2 function mobile satellite antenna, the function has been increased, you can go to download the latest firmware

I have downloaded the last software and I can't solve this problem.
