Part 18
Accessing Side Ventilation Grids
The operation to further clean the side ventilation grids requires much
more highly technical maneuver. Therefore careful attentions must be taken
throughout the further cleaning operations below. When the main unit is
opened, there must be no liquid spill, no electro-conductive material, no
electric charged device come into the area of the main unit. Please also note
that not to touch any component or cable inside.
Please first disconnect every
cable from the main unit and turn the
LCD panel to straight up position.
Prepare enough space in front of the HT
system and lay a piece of clean soft
clothe of appropriate size there to
prevent damage. With the back cable
cover opened, push in the circled spring
button in the right picture on both sides
of chassis and raise the rear edge of the
top cover. Apply some mild maneuver if
there is already a pole display mounted.
Cleaning for Side Ventilation
Use vacuum cleaner to remove any dust or threads accumulation
away from outsides of both ventilation grids on chassis exposed after removal
of the front cover as in pictures below and close back the top cover when done.
