Colored dots on the screen

A PDP (Plasma Display Panel), depending on its size, contains from 0.9 to 2.2 million individual cells. Even with advanced technology it is inevitable that a few defective cells may be found in the PDP. These defective cells may be visible as colored dots. We continually strive to minimize the number of defective cells but the existence of a few such defects will not be considered as sufficient reason for exchange or refund.

Earth wire should be connected.

- If the earth wire is not connected, there is possible a danger of electric shock caused by the current leakage.

-If grounding methods are not possible, a separate circuit breaker should be employed and installed by a qualified electrician.

-Do not connect ground to telephone wires, lightning rods or gas pipe.
