Since last month the the channels go scrambled after a few minutes. The box does not freeze as I can still flip through the channels. Turning off the box and turning it back on it works for another 2-3 minutes before scrambling again. I'm running the "MegaTvi 20140820_SU_NA_C4_1TUNER_2GB_TURBO" file.
PS- I've had this problem before with the 7/14 file, but when I updated it to the 8/20 file a month ago it solved the problem. This time it was scrambling after 30 minutes, but when I tried the old solution again it made it worse as now its just a few minutes.
Is there anything I can do to fix this? I've tried different LNBs, wires, resets etc. but nothing seems to fix it. Thanks.
