There sould not have been sparks. Check the following: Using a voltmeter check between the cable itself and ground. There should not be any reading (anything less than .1V is normal). Check again between the inner hole of the RF connector and the outside part. Again there should be less than .1V. If you read any voltage at the RF connector, the TV is faulty and should be exchanged. If you read voltage at the cable, have teh cable company check again.

You do not indicate if you have auto programmed the television to get digital channels, If you are selecting a channel without a decimal point, for instance 82.3 is NBC hd in my cable system. If your cable provider does not produce these on direct cable then you can not get HD without a box.
Try to Auto Program your tv in the cable mode STD format, this can take up to 20 minutes to complete scan including deleting scrambled channels. After programming try the lowest or highest analog channel like 2 or 70, channel down or up from there to see if any digital channels appear.
