Our projector uses a single LCD (Liquid Crystal Display) panel. This very sophisticated panel contains Total of 181,470 dots

(RGB Trio 60,490 Pixels)

TFTs.

(Thin Film Transistors). As with any high technology electronic equipment such as large

screen TVs, video systems and/or video cameras, there are certain acceptable tolerances that the equipment must conform

to.

Sharp’s acceptable tolerances permit a total of six (6) inactive

TFTs,

which may result in illuminated dots on the picture

screen.

This will not affect the picture quality or the life expectancy of the unit.

*Specifications are subject to change without notice.

the lamp.

2. Allow one hour for the unit to cool down before

servicing.

3. Replace only with same type lamp. Type

CLMPF0044DEOl

rated

6OV/125W.

4. The lamp emits small amounts of UV-Radiation,

avoid direct-eye contact.

Replacement

Note:

Since the lamp reaches a very high temperature

during units operation replacement of the lamp should

be done at least one hour after the power has been

DANGER

Never turn the power on without

the lamp to avoid electric-shock or damage of the

devices since the stabilizer generates high voltages

at its start.
