Notes when visiting for service
1. Notes when disassembling/reassembling

Rear case
When reassembling the rear case, the screws must be tightened in a
specific order. Be careful not to tighten them in the wrong order forcibly.
For details, see "Rear Case" in "7. DISASSEMBLY".

Attaching screws for the HDMI connector
When attaching the HDMI connector after replacing the Main Assy,
secure the HDMI connector manually with a screwdriver, but not
with an electric screwdriver. If you tighten the screws too tightly
with an electric screwdriver, the screw heads may be damaged, in
which case the screws cannot be untightened/tightened any more.
