Troubleshooting

For the sake of time and cost, it is strongly recommended that you check out

the problem by yourself according to the instructions listed hereunder before

contacting the after-sales service for technical assistance.

Note:Production of the screen requires high and precision technologies. However,
there might be some dark or bright (red, blue or green) spots, or some anomalistic stripes or
spots. This is not defect. If the TV set is used in an area 2,400 meters above the sea level where
the air pressure is below 750hpa, the picture on the screen may be affected and a muffled sound
might be produced. These phenomena might happen in the area 1,500 meters above the sea
level. This is resulted from difference between air pressures inside and outside the display. This
is not a defect covered by the limited warranty.

NOTE: Design and specifications are subject to change without notice.

The dimension in this manual is a approximation.
Note: Do not leave the television with static picture in an extended period as it may result in
residual image on your television screen.
