I have the following problem in DM 800 (Enigma 2). There are a few channels that sometimes work and sometimes don't. When they don't work (no picture) the SNR drops tp 0 (before it is 14=15db) but AGC is 99%. Usually a restart solves the problem. It seems that it may be an LNB problem. I read somewhere that sending more power to the LNB will probably solve it. Does this mean that I need to increase the Tone Amplitude in the tuner configuration ? Right now the value is 800mV ? If so how much should it be ?
Any help will be greatly appreciated.
