Before you review the list of problems and solutions below, use Picture Test to determine if the
problem is caused by the TV. The Picture Test displays a high definition picture you can examine for
flaws or faults. If the test picture does not appear or there is noise or distortion, the TV may have a
problem. Contact Samsung’s Call Center for assistance. If the test picture is displayed properly, there
may be a problem with an external device. Please check the connections. If the problem persists,
check the signal strength or refer to the external device’s user manual.
