Weak Signal on some HD Channels

I've got the box off and there is another tris-102A in there. Plug my box direct into this then?

Tried plugging straight in, SNR upto 70% but AGC still only at 7%. Ideas?

Unfortunately not, don't know anyone else I trust with virgin. Should I definitely be removing one of the tris units? One is big than the other. Would replacing it with a new one make any difference?

Yes - you only need one of these on the line and having more than one can lower your signal. These are genuine VM equipment and rarely fail - could try swapping them around to see what the difference is, if any.
 
Is there any difference between the two, ones a tris 102A and the other is a tris 1002AEN?

Swapped them over and still the same. What would you try next? Hd sports 1 has snr 90 agc 91 ss2 snr 86 agc 53 ss3 snr 75 agc 17 ss4 79 agc 25 ss5 snr 64 agc 5 ssn 68 agc 7 ssf1 snr 75 agc 17 ssmix snr 70 agc 7

What do these results point too?

It could be a number of things ... trouble is, as you don't have another house you could try the box in and you're not a VM customer, your options are limited.
 
Are you thinking it could be the tuner/vu+ then? If I wanted to try replacing the isolator which should I buy?

It's prob not the isolator but that one on flee bay is the same one as I have the tris-1002L

Also as a test completely power off the box. Give it say a minute, power up and do a new service scan, run the ABM and epg refresh. If the box is the only thing connected your signal should be strong enough.

I've been having the same issue. I changed the cable wire from a maplin one to a proper cable wire and everything working fine.
The set up I have is isolator...cable wire to splitter and then 1 cable wire to BB and other to tuner.
Try using a proper cable wire. Solved my issue.

Click to expand...

Which wire do you mean, from the isolator to my box or from the brown box outside? From the isolator to the box I have already replaced with wf100 as recommended by ste on another thread.
