I replaced the main board previously as it may have gotten jostled in a move. Main board burned out again, but now any device I hook up to HD inputs causes high voltage arcing. Would like to fix main board, but it will burn out again unless source of arcing is discovered. Thanks!

Hi,
You can confirm new convergence issue cause by installing old audio-video board back and also check all connectors are plugged properly in respective jacks in circuit board.
Can you post wavy lines screen image here to diagnose its possible cause?
That will give me better idea to diagnose problem.
Thanks.
