A
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 "7. 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
B
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
