[Dunner]

My name is Dunner I have two DN500s one works perfectly the other when scanning wont lock on some transponders, I have tries several different images no change, the connection lead from the one that works properly no change when I bought the second box a clone I also bought a new tuner for the original box (not a clone) and had it fitted but it is still the very same when I scan I will get a load of BBC1 channels from different areas but not London nor will I get BBC2, BBC3, BBC4 or Film4 it does scan on both H & V and this is while using the same Dish, LNB, Cables and telly one box works properly the other does not pick up all the channels but the channels it does receive are picture perfect. I really need some help with this as I have spent so much time on it many thanks > Dunner.

I assume that you have already done a full back up of the good box and transferred it to the problem dreambox?

My Dm500s is completely dead.

I would like to thank all at Digital-Kaos and their members who kindly offered me their help with my DM500s I still think they are a great box but I was unlucky with the person I bought it from. Thank you for all your help > Dunner.
