On the local CBS station we continue to have a problem with the screen pixelating or going to a solid yellow. Except during storms, this problem does not occur on the other channels. The local CBS station in Columbia SC is WLTX. Reported to Dish tech support who advised me to call tech directly when it happens again so they can see the problem as it occurs. Also, when we play back a CBS program on the Hopper dvr the same problems occur, especially on prime time programs. Starting to think CBS is doing this purposely to sell their own on demand subscription service!
Are you getting your locals through an OTA, or through your Dish services? If through Dish, what receiver model do you have? It should say on the front left side. Are you able to safely see if there is anything caught in the Dish outside? Sometimes sticks and debris can get caught in the Dish causing issues with pixelation.
