First put yourself back to when you last remember wearing your shorts. Okay, but seriously, you need to isolate the short. In the case of pass-thru power taps, you either need to use a stop-power face plate or a tie-wrap or other non-conductive material to stop the mechanism that passes power when the tap-plate is removed.
I have found 7 out of 10 shorts are connector related. Either the cable center conductor is bent & cause the seizure mechanism in the connector to short out or the pin is too long on the connector & shorts in the equipment. In UG &MDU situations if the splicer was sloppy when prepping the cable the aluminum scrap can fall into the cored out cable end & create a short that is the dickens to find.
The previous examples are mostly from new build/re-build/upgrade situations. If this is existing plant that has a catastrophic failure short, again try to isolate. Now you're job is harder as it could be burnt out equipment, or damage to the coax from fallen branches, a pole hit, lightning strike, or the dreaded underground sprinkler system installation that nicked the jacket of the cable & over time the water seeped into the insulation to create a short. Or it could be the tech from the HBO comercial sitting on a pole using a screwdriver to wreak havoc.
