Sky stream pixelating

[cookiemonsteruk]

Ever since a power cut lasting a few hours channels on sky stream are pixelating from a total screen freeze to squares appearing on the screen for a few seconds. Any ideas ?  

The only thing i have noticed is the down stream noise margin has gone down to 1.8 Db and was wondering if the low noise margin could be letting errors through resulting in pixelation.  If thats the case guess i'll have to wait for dlm to take effect

@cookiemonsteruk sorry to hear that @cookiemonsteruk hopefully the cabinet will have reset overnight. Sky can order a DLM reset but are very reluctant to do it in my experience.
