Hi,

I have a problem with my new DishTV s7070. It won't boot when the LNB-in is connected! It boots fine when the LNB-in is disconnected. If I try to connect it while it's running, it will immediately reset and not boot.

Is this likely to be a problem with the STB or the cable/LNB/dish?

Many thanks.

Most likely an issue with the cable shorting out, check all connections to make sure that there are no strands from the outer shielding touching the inner core (it can take a a single strand to create a short circuit).

The screw! The short was caused by the screw that pinches the core within the cable connector. Even when fully screwed in tight it was touching the outer housing (can i get my money back on the connector?). Thanks for the clue :-) Now to try and find some channels...

Woohoo! It works, connected to an old dish that's not been used since I moved in (so for at least 4 years).

F types don't have screws, they are crimped on. Buy a crimping tool and do things properly.

What's an F type?

My one is now neither crimped or screwed - just floating around in the socket

Post a picture of what you have on the end of the cable. It sounds like you have the wrong plug or something.

This...

http://www.dse.co.nz/dse.shop/4da0269c010716ca2740c0a87f3b0685/Product/View/P2090

inside there is a plastic widget with a tiny screw for attaching to the coax core.

I had two problems:

1. the screw was touching the outer housing even when completely screwed in (no cable attached) causing a short (i think the screw hole was drilled in the wrong place, slightly too close to the end).

2. the core of the cable was thick enough to insert into the plastic widget, however the screw would not engage because the core was taking up all the room not allowing the screw to 'bite' into the copper housing within the plastic widget. The core is too thick? The housing too small? i dunno

Solution:
throw away screw! connect and hope for the best :-) working so far...

First issue is that your plug is for RG59 rather than RG6 which has larger diameter. Second issue is that it is not crimped because it is for terrestrial rather than satellite runs which have a DC current running up the core. Buy a crimping tool and use P2015.

So I bought a 10m internal extension and a new connector. Works no probs (although strength dropped from 80% to 79%). The new connector has the screw hole drilled further from the end and thus doesn't the touch housing.

OMG, I cant believe that plug exists! combining the worst of the cheap nasty belling lee plugs, and the worst of F connectors into one hell-plug.

I suspect that it is made to allow people to use a stranded coax cable and connect to an F plug, and stranded is useless above VHF so quite why that plug exists is a mystery.

There are proper screw on F plugs that use the core of the coax like the crimp on ones that are fine when not exposed to moisture.

Hmmm, if the kid at Dick Smiths didn't assure me that it was the correct plug then I'd be thinking maybe I had the wrong plug about now.
