2. M maintenances Description

To remove the rear shells of the screen, placing the screen face down on the

flat table is recommended to do first, then screw out the hanging strip on the

left.

Figures above shows the location and the type of every screw, after screwing

out all these screws, the rear shells can be removed.

Please note that the tightening torque used must be compliant to the

reference value of specific type of screw showed above. Otherwise the screw

may be permanent damaged.

2. Maintenance Description

▓ To replace the circuit board you need to remove first the rear covers, the

lower terminal block, the side terminal block and wires. Remove the power

before performing replacement, so as to prevent any short circuit resulting

from contact of wires.

3. Maintenance Description

▓ To replace the internal cables you need to remove the rear covers first, and

then remove the cable clips and the adhesive tapes fixed on the screen (

showed as below ).

▓ when the step above is done, pinch the cable plug and press to unlock, then

pull out the plug from the socket. ( To the cables without lock structure, just pull

out the plug from the socket )

▓ unplug the another plug of the cable to finish the cable removal.

▓ Plug a new cable to replace the removed one, and fix the cable back to the

screen by cable clips and adhesive tapes.

Please note whether the ports of the cables are properly connected in

order to prevent the component from being burnt due to inserting in the wrong

Cable clip Adhesive tapes

ports.

Some cables ( such as HDMI Cable ) are fixed on metal structural parts or

even circle boards with screws, to replace these cables, unscrewing the

screws shall be done first.

Cable replacement must be operated under the condition that all power

supply has been fully cut off.
