09. Before calling for service
• Before calling for any repair, check the following and then refer to a near A/S center.
▶
"Tick" sound from the main body.
• If there is no problem with the screen or sound, the "tick"
sound is likely to result from the cabinet lightly shrinking with
the change of room temperature. The sound does not affect
product
’
s performance.
▶
No image at upper and lower part of the screen.
• As for a screen which is over 16:9 in width (such as cinema-
sized one), no image may be displayed at upper and bottom
part of the screen.
▶
Speckles or white lines on the screen
• Check whether the problem is caused by vehicle, streetcar,
high-voltage cable or neon sign, which emitting interference
wave or electromagnetic induction. Avoid any interfering
object.
▶
Light leakage can be found at the edge areas around
the screen.
• If the light leakage is not detected at 1m from the screen, the
panel is considered as no defect.(SAMSUNG LCD applies the same
inspection standard)
• To minimize the light leakage, the MLCD sets should be installed
with high accuracy in horizontal and vertical position.
