How to configurate a Dreambox 500 S on C band?

[Finder2]

Hi
I've got 2 Dreambox 500 S for me and a friend of mine, but I've tried so hard to configurated them on C band,but I got zero channels locked when I asked them to perform a scanning.
I'm using Plijade Image and a Chieta DiseQc 4x1 . I'm sure there's not an instalation problem because when I disconnect a DM 500 S and connect another decoder, at the same place all channels work very well, Ku band and C band.

I've configurated DiseQc simple, it doesn't work. So I configurated non.standard user defined configuration. LNB 0 and LNB 1 C band satellites, LNB 2 and LNB 3 Ku band satellites. Of course I've configurated C band LNBs LOF/L to 5150.

There's strong sinal on TPs SNR and AGC but the scan returns zero channels locked.

Today It there were a few channels working here, but when I changed de decoder from here to anoter TV set , in another room, there are no channels to watch again !

What's going on? How to configurate, correctly, a DM 500 S on C Band?

Thank you very much - from Brazil

Finder, I know next to nothing of C band, not really used much in Europe, but try setting

LOF/L: 05150
LOF/H: 05750
Threshold: 06500

Hello!
i just found this post over google news alerts!

on some cband channel you have to set invertation on,that you can lock,usaly the dreambox,and this only in cband happens
change the polarity for example H on a other receiver is on dreambox vertical and via versa!
often,the lnb drift ,is also a problem of some cband lnb,try to make the freqency on or to mhz higher then it work fine!
good luck!
