DVB-S2 Tuner Fail - DVB-C/T/T2 fine

[cfkodi]

Hi,

I purchased this great STB from yourselves on 02/10/2016

Xtrend ET8500 1x DVB-S2 + 1x DVB-C/T/T2 COMBO Linux Enigma 2 Linux HD Digital Receiver PVR Ready
- Enigma 2 Firmware / Image Options (Flashed Free Of Charge): OpenXTA (Nightly Bui..
- Fitted HDD Options: 500GB HDD 2.5" ..
- Networking Powerline Homeplugs: Not required
- USB Storage: Not Required
- USB WiFi Option: Not required

Since April It doesn't find a signal on the DVB-S2 tuner.
I have tried it on vix, openatv, various versions
I swapped it to a different slot
The sat connection is fine because I've plugged it into another box and a signal is found.
The card is recognised by the box but when you tune it picks up nothing
ABM fails straight away
I have exhausted all avenues, unless anyone else has any ideas?

DVB-C/T/T2 works perfectly
