Few days ago no channels were showing in my dm800hd, the info was there but no picture or sound so i rebooted, on reboot it said 'check tuner configuration'. Tried flashing several times and reboots, it would alternate between 'check tuner configuration' and showing no tuner present at all to saying 'tune failed' for every channel but the tuner A would show something there.
Yesterday I used dreamboxedit to upload new bouquets to the box and after reboot and lot of fiddling in channel list and what not, the channels started to work fine. Now again today im getting the 'check tuner configuration'.
The fact that I did get channels fine yesterday would mean my sat dish and cabling is ok, so does this mean I should invest in a new tuner? And to replace it, is it just a simple case of unscrewing or is soldering involved?
