I have a TF2401CI+ for some years, always working well, with 3 Diseq 1.0 for 3 lines coming, 2 for the TF, HotBird, Astra and Atlantic Bird 5.0W, and 1 directly to TV.
For some weeks, ONLY on Atlantic Bird (AB), for Bis TV (french provider) and ONLY ON TUNER 1, I always have for a second the signal that goes to minima and then back to his normal quality (78 % signal level and 98 % quality) . It gaves poor pixellised images. Then, changing channel for i.e. RTS (HotBird) and then back to AB, it's ok, until the next time.
I have checked the LNB position for AB, changed the LNB, changed the cables, and finally changed the Diseq module. The problem is still there, but with a minor frequency. I'm becoming crazy, because I have no idea on what can give this and what can I do more that what I have done...


Help needed, please, thanks in advance, best regards,
Raymond
