10 . PROJECTOR
10 - 1 CLEANING THE SCREEN
Since the Projector has been adjusted at the time of shipment,
avoid making further adjustments without good reason.
The Projector is subject to color deviation due to Convergence devia-
tion caused by the geomagnetism at the time of installation location
and peripheral magnetic field. After the installation of machine, and
before commencing operation, check for Convergence deviation and if
deviated, make adjustments..
Since the Projector screen is susceptible to damage, pay careful
attention to it’s handling. When cleaning, refrain from using water or
volatile chemical.
Fine adjustments are stored in the Projector. Pressing the Fine Adjustment SW (Convergence
Adjustment) results in entering the Fine Adjustment mode, and this may cause the stored fine
adjustment to be changed. During work other than for adjustment, Should you topuch the Fine
Adjustment SW by mistake, immediately turn power off by using the main SW and then turn it back
on again. If any distortion or color deviation is found in the test mode and adjustments are needed,
use the specified adjustment knob, or perform adjustment by remote control. To find the adjustment
knob, move Cabinet DX and remove the PTV Front Service Door by using the procedure opposite
the one for installing and assembling. In some cases a cover is installed to the Adjustment Knobs.
Remove the Cover.
When the screen surface becomes
dirty with dust, etc., clean it by using
a soft cloth such as gauze. When
water, and volatile chemicals such as
benzine, thinner, etc., spill on the
screen surface, it may be subject to
damage, therefore, do not use them.
Also, since the surfaces are suscep-
tible to damage, refrain from rubbing
them with a hard material or using a
duster.
