If the problem persists while changing channels from analog to digital television, it may be an issue with the cable box or satellite box (if you're using one) or could be the television. If you tried troubleshooting this with other devices, if the variable still seems to be the television, I would recommend contacting the Samsung customer service center in your region for further troubleshooting assistance.
