"Bobbie" obviously has never had this experience. Her answer, to put it gently, is not likely to succeed.
If your TV is a plasma set, you *might* be able to recover from this error. If it's an LCD (including LED versions), the display is almost certainly ruined.
Replacing the display is a job for a professional, and the cost will approach or even exceed what you'd pay for a new TV.
Tell Hubby, as his penance, to memorize the proper TV screen cleaning process in the link below.
