TV sparking when hooking up cable

I just moved my tv into my new home and the tv turned on fine but when the cable guy went to hook the cable up to it would start sparking. I did not know if anyone knows how to fix this problem.

    The connector for cable. Everytime the cable guy plugs the cable into the back of the tv there is a spark and a popping sound.

    Thank you for your help. Around the connector for the cable now is black, like it is burnt. The cable guy said when we intially unplugged the cable while moving it might have stripped a wire and that is causing the spark.

    What exactly is sparking? The connectors, the actually TV? is it sparking when you try and plug something into it?

Hi, there is a sparking sound probably because whatever your cionnecting it from is still on. So switch of the unit where the cable is coming from, maybe its froma signal booster? and plug it into your tv, also there maybe still current running through your tv so switch off your tv aswell. It is quite common for connectors to spark when the equipment is on because the connector is try to make contact and there is a voltage present. I'm guessing that the TV works fine once the connector is inserted in or hasnt your cable guy gotten that far yet?

As long as its not a large spark and the source which the cable is connected to is not a high voltage source, which I dont see any reason why it should be. Also check the grounding of the cable. Considering you have a cable guy installing the equipment I'm suprised they do not know whats going on.....

Regards
Rob

I DON'T KNOW HOW TO CHANGE MY TV TO CABLE OPTION RATHER THAN UHF OR VHF


Well let me ask some questions!
1) UHF and VHF are types of off air antenna source signals.
2) Cable TV has both the Analog 'UHF and VHF' signals on them along with the new Digital TV signal sources.
A) Is you TV have a Digital Tuner built into it or are you using a CABLE TV box to hook up to your TV?
Blessings always,

Try an antenna directly on the tv to see if you get any stations. This will assure you that the tuner is working. Then hook up the new box and tune tv to channel 3 and turn box on. You should get some kind of display. If no luck you could hook audio/video cables from the audio/video output on the box to the video 1 input on the rear of your set. Then switch tv input to video 1 and turn box and tv on. This too, should give you something on the screen. Make sure the antenna is hooked up to the "ant. in" on the box. This should help, Russmann.

Try using different inputs besides the RF input. Connect your PS2 and DVD player using component inputs. With two component inputs, there's no reason in the world not to do this.
