Trouble with Uni-cable setup

I have had my Gigablue UHD Quad 4k for almost nine months trouble free viewing, using a GT-SAT GT-S3DCSS24 uni-cable LNB. Then one night a couple of weeks ago it stopped working, no signal, after a few checks I decided to buy a new LNB.
I now have the same Gigablue box with a new un-cable GT Sat GT-S2DCSS24 LNB, that I cannot get to work, my current LNB configuration is:

Configuration mode Advanced
Satellite (6) 28.2E Astra 2E/2F/2G
LNB LNB 1
Priority Auto
Type of LNB SCR (Unicable / Jess)
SCR (Uncial / Jess) type SCR (Uncial / Jess) LNB
Model GT-S2dCSS24
Manufacturer GT-SAT
Channel User band(10)(1425) Note**** I have tried a few user bands nothing seems to work. Although I do pick up one or two ITV programs.

External Powered No.
DiSeqC mode None
Forced Legacy signal stats No.

Tuner B is not used, C,D,E,F,G and H are all set to FBC automatic.

When I use the legacy Universal outputs from the LNB I get a good signal and can receive all freesat channels.

Latest software flashed at the weekend, to make sure there are no bugs.

Any help will be most welcome.
