A kink in the cable would not cause that. Again no colors are being sent accross the wire, only a radio signal which needed to be decoded at the other end by the receiver.
When you are tuned to lets say HBO your receiver is actually is actually looking at a full transponder off the satellite it then decodes the transponder and finds the correct stream for HBO (On that transponder is also 8 other channels), decodes this stream and then displays it on your TV.
A kink in the cable could cause problems in the analog world, but we are not in the analog world here this is digital a bunch of zeros and ones with error corrections.
Again it's not the Dish or the switch thats the problem.
