How do I find the number of hours on the set so far? Thank you.
This is how it was done on the VT20:
Press and hold the {VOL -} button ON THE PLASMA TV.
Then press the {INFO} button on the remote control 3 times.
"Start Adjustment Menu" message will be displayed followed
by the Service Menu after few seconds.
ADJUST {Picture Adjustment}
WB-ADJUST {White Balance Adjustment}
OPTION {Option Setting}
V-SUS {V-SUS Adjustment}
AGING
SRV-TOOL {Service Tool}
{1} & {2} buttons move through options
Press the {2} button once to select "SRV-TOOL".
Then press the {OK} button to access it.
Using the cursor keys, highlight the right side
of the last item "PTCT :00.00.00.00.00" :
Then press and hold the {MUTE} button for 3 seconds.
Time and Count will be displayed in red color:
__TIME = Hours : Minutes of operation.
COUNT = Times the Plasma was powered on.
To exit, unplug the power cable.
The {VOL+} & {VOL-} buttons are used to change values
while in the Service Menu. Make sure not to touch those
buttons anytime while checking the hours used.
