PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in television receivers have special safety related characteristics. These characteristics are often not evident from visual inspection nor can the protection afforded by them necessarily be obtained by
using replacement components rated for higher voltage, wattage, etc.
Replacement parts which have special safety characteristics are identified in this service manual.
Electrical components having such features are identified by shading on the schematic diagram and parts list of this
service manual, and by marking on the supplementary sheet for this chassis to be issued subsequently . Therefore,
the replacement for any safety part should be identical in value and characteristics.
Page 5
MODEL: WD-52631 / WD-57731 / WD-65731
SAFETY PRECAUTIONS
NOTICE: Observe all cautions and safety related notes located inside the receiver cabinet and on the
receiver chassis.
WARNING:
1. Operation of this receiver outside the cabinet or with the cover removed presents a shock hazard
from the receiver's power supplies. Work on the receiver should not be attempted by anyone who is
not thoroughly familiar with the precautions necessary when working on high voltage equipment.
2. When service is required, observe the original lead dress. Where a short-circuit has occurred, replace
those components that indicate evidence of overheating.
SAFETY PRECAUTION
To protect your eyes, do not look directly into the lamp, or light coming directly from the lamp, lens or
mirror.
Leakage current check
Before returning the receiver to the customer, it is recommended that leakage current be measured according to the
following methods.
1. Cold Check
With the alternating current (AC) plug removed from the AC source, place a jumper across the two AC plug
prongs. Connect one lead of an ohm meter to the AC plug and touch the other lead to each exposed metal part
(i.e. antennas, handle bracket, metal cabinet, screw heads, metal overlay , control shaf ts, etc.), particularly any
exposed metal part that has a return path to the chassis. The resistance of the exposed metal parts having a
return path to the chassis should be a minimum of 1 Meg Ohm. Any resistance below this value indicates an
abnormal condition and requires corrective action.
2. Hot Check ...Use the circuit shown below to perform the hot check test.
1. Keep switch S1 open and connect the receiver to the measuring circuit. Immediately after
connection, and with the switching devices of the receiver in their operating positions, measure the
leakage current for both positions of switch S2.
2. Close switch S1, energizing the receiver . Immediately after closing switch S1, and with the
switching devices of the receiver in their operating positions, measure the leakage current for both
positions of switch S2. Repeat the current measurements of items 1 and 2 after the receiver has
reached thermal stabilization. The leakage current must not exceed 0.5 milliampere (mA).

Front Panel Initialization (new in the V33)
While the unit is ON, pressing the FORMA T and INPUT buttons simultaneously will immediately start the Initialization
sequence. The TV will reboot once the initialization sequence is completed. Front Panel Initialization will reset ALL
user settings to the factory setting.
SERVICE TIP:
Many customer generated symptoms, intermittent symptoms or no symptom found can be resolved by system reset
or initialization. Before visiting the customer’s home ask the customer 1st to try the System Reset button on the
control panel and if this does not resolve the issue, then they can use the front panel initialization by pressing the
FORMA T and INPUT buttons simultaneously
NOTE: During Initialization, the set will
reboot. Wait until the Power LED stops
flashing before unplugging or powering

problem has occurred since the last Initialization.
Note: The front panel buttons must be used, NOT those on the Remote Control.
tional Check. When the TV is switched Off, the code automatically resets to 12 No Error.
The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
The flashing then pauses for approximately 1/2 second.
The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
The Error Code is repeated a total of 5 times.
Example: If the Error Code is 23, the LED will flash two times, pause, and then flash three times.

Use the above Error Code Table, the Lamp Control Block diagram, and the Troubleshooting flow chart on the following pages
to determine is a lamp problem is due to the Lamp, Ballast, Power Supply or Light Engine.
(1)
- Lamp Enable is generated to activate the Lamp
(2)
- Lamp Enable is generated during P-ON sequence, but no Lamplit signal is received from the Ballast.
(3)
- No Lamp Enable is received at the DM and Ballast.
(4)
- Lamp enable is received at the DM but not at the Ballast.

SYMPTOM
POSSIBLE CAUSE(S)
POSSIBLE RESOLUTIONS
1
No channel map appears when pressing
guide button (TVGuide disabled)
Cable is not connected to ANT1 -orOOB data is not received correctly
1) Verify cable is connected to ANT1
2) Re-install/Replace CableCARD
3) Verify signal level and signal noise level
4) Contact Service Provider
5) Check TU101 for proper function/Replace Signal PWB
2
Channel map does not change after card
is installed. (still showing basic cable
map)
CableCARD is not ’Initialized’ within
the service providers system. Contact service provider
3 Host ID screen does not appear
Signal and information not received by
TV
1) Verify cable is connected to ANT1
2) Re-install CableCARD
3) Replace CableCARD
4) Verify signal level and signal noise level
4
Error code received on screen. Error
codes are listed such as 161-x
Communication between TV and card
is lost or disrupted
1) Pull card from TV and wait 5 minutes. Then reinstall the
card and verify it is initializing properly.
2) Press INPUT & FORMAT keys on the front panel.
3) Replace CableCARD with new card
4) Try 3rd CableCARD
5) Replace DM-PWB
5
Individual channel cannot be received.
(example HBOHD is no video and no
audio but other HBO channels are OK)
The TV has no means to block
individual channels. Proper
authorization is not received.
Contact service provider
6
Certain tier of channels is not received.
(example: Premium channels or all HD
channels not received)
Authorizations to display scrambled
channels are sent via OOB data.
Contact service provider
7
Unable to tune to a channel. (example:
Pressing 1055 has no response and
stays on current channel)
1055 is not available in the channel
map. Channel map is sent via OOB
from the service provider.
Verify OOB is locked. If OOB is locked, verify channel
should be received. If not locked, troubleshoot for OOB
failure on SIGNAL PWB and/or with service provider.
8
When using SA card channels changing
automatically and random message
about upgrade in process. (Channels are
often like 10,000 to 50,000)
CableCARD firmware is out of date
and being upgraded by service
provider.
If this process continues more than 60 minutes, contact
the service provider for updated card
9
Periodically encrypted channels become
unavailable.
Card is hung Unplug card or AC or perform initialize
10
Only Analog channels can be viewed. All
digital/encrypted channels are
unavailable
Proper authorization is not received or
TV cannot display digital video
1st test for QAM clear channel (often network channels are
provided free), if no QAM clear channel is available
remove the card and memorize channels. Verify that a
digital channel can be viewed. If known digital channel
cannot be viewed suspect SIGNAL
11
ChannelView does not list program
content or channel call letters
This information is provided in the
form of OOB data tables and is sent at
the discretion of the service provider
Contact service provider
CableCARD
Cable providers send QAM64 and/or QAM256 through
the coax cable to the TVs tuner. Once converted to IF it is
demodulated to an MPEG transport stream (TS). If a card is
present in the PCMCIA slot the TS will be passed to the card
and returned back to IC8506 and then finally sent to the Xilleon
processor. If there is no card present in the card slot and the
tuner is tuned to a QAM channel the TS will pass directly from
the POD interface IC directly to the Xilleon for processing.
Cable providers typically have both encrypted
and unencrypted channels. If the Xilleon receives an
encrypted TS it will ask the CableCARD to unscramble
the stream. The card will only unscramble the TS if it
receives the proper authorizations to do so. Those
authorizations are received via Out-of-Band data (OOB).
The OOB contains information about authorizations,
channel maps and more.
