Symptoms
Checks
Some parts of the screen do not
light up
The plasma display panel is manufactured using an extremely high level of
precision technology, however sometimes some parts of the screen may have
missing picture elements or have luminous spots. This is not a sign of a
malfunction.
Afterimages appear
If still video images or computer images are displayed for long periods of time, an
afterimage may appear. In such cases, display an image which has some degree
of movement in it to reduce the afterimage effect.
Before you call for service, determine the symptoms and make a few simple checks as shown below.
