Part D. Overall Process of Disassembly & Reassembly

A. Operation video of replacing OC backlight module & OC optical bonding module:

https://www.dropbox.com/s/z1ceo6qw9l4kuq2/VN_OC%20module_Disassembly%20%26%20

Reassembly.mp4?dl=0

Operations involved in the above video:

1. Take off rear covers, remove all PCBAs.

2. Take off OC backlight module.

3. Take off OC optical bonding module.

4. Install OC optical bonding module.

5. Install OC backlight module.

6. Install all PCBAs, fix cables and install rear covers.

Note:

1. The above operation 2-5 MUST be done in a dust-free plant to avoid the dust stick onto the

glass or backlight module surface.

2. Must use a suction cups tooling (see it in the above video clip) to fix the glass to uplift it,

don’t uplift OC optical bonding module by hand directly which will destroy it.

B. Operation video of replacing IR touch PCBAs:

https://www.dropbox.com/s/ymhpyblklmjswe9/VN_IR%20PCB%20SET_Disassembly%20%26

%20Reassembly.mp4?dl=0

Operations involved in the above video:

1. Take off 4 corner covers, there is no connection in the upper-right corner in front view, from

right to left to remove upper IR PCBAs, from bottom to up to remove the left and right side

IR PCBAs, from right to left to remove the bottom side IR PCBAs.

2. According to IR PCBA layout and refer to above opposite order to insert the 4 frames IR

PCBAs.

3. Connect the bottom-left, bottom-right and upper-left corner PCBA, pay attention not to
