Hi to all,
Please, I need your help regarding an issue with my DM800. Lately it is shown the famous message "tune failed" in many channels on different satellites. I changed the three LNBs that I was using so far, but after several days it's the same situation. I tested with 2 other Dm800 boxes and it was the same problem, but another DM500 is working fine with the same LNBs. My DM800 is working fine in another location. I even tried the command "echo # > /proc/stb/frontend/0/tone_amplitude" - this value fixes the Diseqc-problem with se veral values, but no results, the same situation.
Any idea what to check next?
Thanks in advacne for your help
