Graphical Symbols
This lightning flash with arrowhead symbol, within an equilateral is
intended to alert the user of the presence of uninsulated “dangerous
voltage” within the product’s enclosure that may be of sufficient
magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert
the user of the presence of important operating and maintenance
(servicing) instructions in the literature accompanying the appliance.
This service manual contains various CAUTIONS and WARNINGS
indicated by triangular warning symbols, which should be read and
understood in order to minimize the risk of personal injury to service
personnel and customers. The possibility exits that improper service
methods may damage the equipment or result in property damage or
user injury. It also is important to understand that these CAUTIONS and
WARNINGS are not exhaustive. PDI could not possibly know, evaluate
and advise the service industry of all conceivable methods in which
service might be done or of the possible hazardous consequences
of each method. Accordingly, a servicer who uses a service procedure or
tool which is not recommended by PDI must first satisfy themselves
thoroughly that neither their safety nor the safe operation of the
equipment will be compromised by the service method selected.

Remote Control
The P10LCD requires a remote control (part number PD108-412) to program the set. You will
NOT find a remote control packed with the television. The remote control is shipped separate
from the television. The remote control has a limited range to prevent dual programming of an
adjacent room TV. Stand within 3 feet or closer from the front of the TV to use the remote.

Disinfecting and Cleaning
The P10LCD should be disinfected before performing any service. The following procedure is
only a recommendation. Your hospital or company may have a different procedure to follow.
CAUTION – Before using any cleaning or disinfecting
agent on the P10LCD, perform a spot check by wetting
a small area of the cabinet. Verify the agent does not
discolor or deteriorate the cabinet.
Disinfecting
1. The P10LCD has been designed to withstand up to a 5% chlorine based disinfectant.
Many alcohol and ammonia based disinfectants have also been tested with success.
However, before using any cleaner or disinfectant, spot check a small area on the
cabinet.
2. Apply the cleaner or disinfectant per its recommended instructions. Note – most
disinfectants require a waiting time following application and prior to wipe-down.
Cleaning
Stubborn ink and other scratch type marks may prove difficult to remove. A dilute solution of
Isopropyl alcohol will generally work when all else fails. However, full strength Isopropyl will
remove the cabinet’s paint. Use with caution!

Hidden Factory Menu
A hidden factory service menu is available to the knowledgeable service man using the following
procedure. To access the menu use the PDI remote control (part number PD108-412).
1. With the TV turned OFF, activate the hidden factory menu by pressing the following
IR remote key sequence:
SETUP + SETUP + 4 + 0
2. The TV will turn ON automatically. The factory screen is displayed..

KBIR Sfw: V 11 CKSUM: 6895
3. The service menu consists of one read-only menu screen which provides firmware
checksum values indicating which revision is currently programmed into each of the
TV’s two microprocessors.
4. Exit the service menu by turning the TV OFF. Or after 30 seconds the TV will
automatically turn itself OFF.

Picture and Power Supply Adjustments
Picture
The LCD display does not use magnetic deflection (like a CRT tube display) and does not require
any internal adjustments. Dynamic picture adjustments to Brightness, Contrast, Color, and Tint
are available using the IR Remote Control part number PD108-412 using the Setup / Picture
Menu.
Power Supply Alignment
The P10LCD television utilizes a fixed-voltage switch mode power supply. Internal power supply
adjustment is not necessary.

Safety Checks
Before returning the P10LCD to service, the following safety checks should be performed.
1. PARTS PLACEMENT
Confirm that the screws, parts, and wiring which were removed to allow servicing are put
back in the original positions.
2. SWIVEL RESISTANCE TEST
1. Expose the mounting swivel.
2. Measure the DC resistance between
the input coax shield and swivel as
shown. The resistance value should
read greater than 1 Meg. A lesser
reading indicates a possible
insulation breakdown or short
between the internal metal U-
Bracket and chassis ground which
could increase leakage currents
touchable by the patient.
3. It is recommended that the reading
of the swivel resistance be recorded
as part of the service record.
3. AC LEAKAGE CURRENT TEST
Following re-assembly of the P10LCD
always perform an AC Leakage Current
Test. Use either an approved hospital
leakage meter or the R-C network shown.
SWIVEL LEAKAGE
a. Power the TV using an approved
external 28 VAC power supply. DO
NOT USE A LINE ISOLATION
TRANSFORMER DURING THIS
TEST.
b. Connect one side of the R-C network
to a good earth ground such as a
water pipe, conduit, etc. Touch the
other side of the R-C network to the
top of the metal swivel.
c. Measure the AC voltage drop across
the R-C network. The measured
voltage must not exceed 0.10 volts
RMS (100 millivolts RMS). This
corresponds to 100 microamperes of
AC current. Any value exceeding this
limit constitutes a potential shock
hazard and must be correct
immediately.
d. Record the reading as part of the
service record.

Document Number PD196-068 R1 14 October 2004 Page 20 of 24
EARPHONE JACK LEAKAGE
e. Now, connect one side of the R-C
network to a good earth ground
such as a water pipe, conduit, etc.
Touch the other side of the R-C
network to the metal ring on the
earphone jack.
f. Measure the AC voltage drop
across the R-C network. The
measured voltage must not exceed
0.10 volts RMS (100 millivolts
RMS). This corresponds to 100
microamperes of AC current. Any
value exceeding this limit
constitutes a potential shock
hazard and must be correct
immediately.
g. Record the reading as part of the
service record.
