echo: post#6 ... post#11 ....

The spark is normal, the Comcast tech obviously shorted the cable against the receiver port.
Replacing the diplexers should buy you some time blahblah, but it will only ever be a temporary solution and a poor one at that. nmetro said it best, somebody didn't do their job correctly by combining the two systems on one cable. I'm leaning toward it being the Dish installer as Comcast techs do not generally have diplexers on them. This is a tough thing to get fixed, should have been done correctly upon installation but unfortunately it is a zero accountability industry.

Comcast should never touch the satellite co-ax lines. If the diplexers were from the Dish installer than it's Dish that needs to come out and straighten thing out. If any damage is done to your E* equipment you would be responsible - not the cable guy.

Not recommending that you should fool with any type of coax with voltage on them for fear of damaging equipment but most receivers either Dish/Directv all have protection circuits for shorts. Even modern wall warts and such all have protection circuits rather than fuses to protect even against sustained shorts that may occur.

Again not saying you shouldnt power down your equipment or that a short will never kill a receiver, just saying. Of course modern receivers do seem like they take an eternity to boot when you are standing there waiting :mad:

The rule is: if you don't know for sure, for 100%, is a device has overload protection, DON'T ASSUME IT HAS !
100% safe to treat it as UN-PROTECTED !
