Just finished up a service call on a Dish Network Satellite System at Triangle Orthopaedics was showing no signal on Flat screen TVS. Another contractor thought it would be a good idea to borrow some of the concrete blocks that weight the Satellite Sled down to the roof and managed to move the whole Satellite Dish out of alignment. Thank you roofing contractor where ever you are as you are keeping me employed lol. All is right with the system once again.
