Problem with Ross freesat HD receiver

[usguvna]

I installed the Ross HD receiver, dish and all. All appeared well, had multiple channels and HD channels. While flicking through the channels it appeared to lock on one channel. Since then 8888 keep flashing on the LED. When I disconnect the cable from the box the 8888 goes away and the load process occur and the channel comes up but without the picture of course. As soon as I plg the cable back straight back to flashing 8888. Any ideas? Is it upgrading? Bad box?

Thanks

Since the post was made on the 27th June, I feel that the OP has probably sorted it by now.
