Ned1 Hd 23.5 is not working

In spark Ned1 hd works not all the other channels are working but Ned1 hd 23.5 east is not working.
in image 1.1.37 ned1hd works all above image not why?
this is the same in the new allrussian image with the rsp image and oscam 3520 ned1 HD is working fine.
Do you have a solution?

I cannot explain why but ... the same problem is on DM800 with Merlin and Oscam, IPBOX 910 with PKt and Ocam
...so ... something is odd with that chanell ! maybe this is due to oscam ... and the image !

rename oscam 3520 to oscam and remove the old Oscam then load the new one give hem 755 and restart the reciver and Ned1 HD is now working.
