No signal issue dd free dish

[jaiganesh]

I am facing no signal issue on mpeg4 slots of dd free dish since yesterday

Audio is breaking and on and off if there is some signal. Video is not coming at all but sometimes a colored screen or half of the channel logo is viewed when signal is little

Please let me know if same is faced by anyone of you and what could be done to overcome this. Is it because of dish / lnb issues or the problem is with the transmission itself?

Thanks

Lnb skew got disturbed. Now corrected.
