1. BASIC ITEMS FOR SERVICE
1.1 QUICK REFERENCE
Notes when visiting for service
1. Notes when disassembling/reassembling
1 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 "5. DISASSEMBLY".
2 Attaching screws for the HDMI and system cable terminals
When attaching the HDMI and system cable terminals after
replacing the Assembly, secure the terminals 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.
2. On parts replacement
1 How to discharge before replacing the Assys
A charge of significant voltage remains in the Plasma Panel even
after the power is turned off. Safely discharge the panel before
replacement of parts, in either manner indicated below:
A: Let the panel sit at least for 3 minutes after the power is turned off.
B: Turn the Large Signal System off before the power is turned off
then, after 1 minute, turn the power off.
For details, see "5.6 [1] PANEL DRIVE-POWER ON/OFF
