Missing channels

[gasher01]

Hi new to this but need answers.
I get no signal on some channels, when ive looked further it seems that it is the V channels that are missing, all H channels seem ok.
Ive already done a system flash and still same.
Any ideas???

Have you got a another Box connected ? as issues with Skybox polarity switching between H & V or check LNB Power Setting.
Had the same issue swapped LNB for an Inverto Ultima sorted problem.

Ive disconnected other box, this makes no difference, also done LNB Power setting to no avail

I've he'd this problem with a very old sky lnb swapped it and all working

Inverto Black Quad ?16.95 on Fleabay can't go wrong. Stand Back when you check Signal Strength on original Sly Box.

This device is designed for boxes that will have a perfect signal on around two thirds of your channels (for instance S*ySportsHD1) but displays 'No Signal' on other channels (commonly S*ySportsHD3 amp; E*PN HD amongst others). If your box has 'No Signal' on every channel or only 1 or 2 channels then this device will not help you, you may need to realign or replace your dish, LNB, cable or connections.
The easiest way to confirm that you have the Polarization selection issue is to go in to your box menu, then Installation, then LNB power setting and change this to 'Off'. If you can now view the channels previously displaying the 'No Signal' message (SSHD3) but not the other channels that were previously working fine (SSHD1) then this device will work for you!

A basic explanation of why this occurs is the LNB on your satellite dish requires a low voltage for vertical polarized channels (around 13 volts) and a high voltage for horizontal polarized channels (around 18 volts). A standard cheap sky quad or universal LNB will operate with the low voltage range as somewhere between 10-15 volts and high voltage as somewhere between 16-20 volts. The problem is the box puts out a voltage of around 16-17 volts for low and 20-21 volts for high which means that the polarization remains horizontal even when it should switch to vertical. A decent quality LNB (like that in a motorized dish) will operate with low voltage as anything below 18 volts and high as anything above 18 volts hence why the box works fine on some set-ups, but not others. Our device corrects this voltage differential without adding any potentially damaging extra resistance to the tuner circuit, such as that caused by in-line amps (which can also lead to you losing other channels in some cases). Using our device means the box will then work properly as the LNB can differentiate between high and low voltage, and in turn vertical and horizontal polarization.

This is my problem, so ive purchased the fix. Fingers crossed.

gasher01 did this fix work mate?

What happens if you install another box put another bodge fix on that one too. Proper fix is to put a decent LNB.

By the way there is a thread for the "No Signal Fix" cost for parts worked out about 10p suppose you paid more than that on Fleabay.
