My sky+hd box won't receive a signal

[Prhillbilly]

My sky hd box is not receiving a signal and on the settings it's getting a good signal,, I've tried switching it off and took the card out but still nothing but the card has brown scorch mark on the top above the microchip i think its knackered,,,

Brown marks are NOT scorching but discolouration of the resin that glue the card together

"No Signal" is an error generated by your TV indicating that it cannot find a device on the current input, check the correct input for your Sky box is selected

"No Satellite Signal" is an error generated by your Sky box and usually indicates an issue with one or more of the following:

• The Dish is misaligned
• The Tuners in the sky box
• The input sockets on the Sky box
• The plugs on the cables
• The cables themselves
• The Sockets on the dishes LNB
• The dishes LNB has gone faulty for the connections the box is using
• You have plugged your Sky+ box into a dish that is only compatible with Sky Q

You may have to call out a local satellite installer, unless you have Sky Protect insurance, to check/fix your system, another option is to move to Sky Q, as during the move all issues will be resolved as part of the install, there is also the option of Sky Glass or Sky Stream, if you want to move away from satellite TV and use the Internet
