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. Therefore, the replacement for any safety part should be identical in value and characteris-
tics.
The PWBs used in the V39, V39+. V39++ and V39- chassis are constructed using Lead-Free
Pb Solder
Downloaded From TV-Manual.com Manuals
solder. When servicing use only recommended Lead-Free solder (refer to page 33).
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 1Meg 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).
1 ) Remove 3 screws (C) from the Optical Engine.
2 ) Disconnect all cables to the Optical Engine Assembly.
3 ) Carefully slide the Optical Engine assembly from the cabinet.
OPTICAL ENGINE REMOVAL FROM THE DUCT ASSEMBLY
Upper Duct Assembly Removal Procedure
1 ) Disconnect the Ballast Fan and Lamp Fan from the back of the Engine (connectors J4 and J8) and loosen
wiring harnesses from the looms, refer to page 1 1 for connector locations.
1 ) Loosen two screws (a) to remove the Lamp Cartridge, refer to Figure 1.
3 ) Remove 3 screws (b) from the top of the upper duct and release the 7 snaps shown in Figure 2.
4 ) Carefully remove the upper Duct assembly

LOWER DUCT (Upper Duct Removed)
1)Figure 3 shows the components in the Lower Duct.
2 ) The Sirocco Fan and Exhaust Fan can be replaced. The Engine and Upper Duct do not have to be removed
to replace the Ballast.
3 ) If replacing the Engine, remove the Thermal Sensor from the Engine (1 screw) Figure 3.
1 ) Remove the 2 screws (C) one in front and one in the rear of the lower duct, refer to Figures 4 and 5.
2 ) Carefully remove the lower duct from the Engine.
ENGINE REPLACEMENT (Reverse the Removal Procedure)
1 ) Install Duct assembly on the new Engine.
2 ) Remove the Protective Lens Cover from the face of the Lens.
3 ) Install the Engine Assembly in the cabinet.
4 ) After a new Engine is installed Load Index Delay Data from the Engine and Copy Settings to
Backup (page 32).
5 ) Adjust Raster Centering (page 28) and Manual Keystone Geometry Alignment (page 29) if
2 ) Open the Control Panel door and remove two screws (A).
3 ) Remove the remaining rear screw in the upper corner and carefully pull the screen assembly
from the cabinet.
Screen Removal From the BEZEL-FRONT
1 ) Remove the screws (A) from the top, bottom and side rails.
2 ) Lift the Fresnel Lens and Lenticular screen from the BEZEL-FRONT.
CAUTION:Wear gloves when handling the Lenticular Screen and Fresnel Lens.
This prevents cuts and finger prints. Do not place Fresnel Lens in the sun.
This may cause fire and heat related injuries.
Lenticular Screen and Fresnel Lens Removal
1 ) Remove the top, bottom and side HOLDER-SCREEN rails and their cushions from the Bezel.
2 ) Lift the screens as a single unit from the frame.
2. Separate the Lenticular Screen and Fresnel Lens.
Note: When separating the Lenticular Screen from the Fresnel Lens, use caution
while prying the Screen and Lens apart. Use a slot type screw driver, and
remove the pressure sensitive double sided tape.
Lenticular Screen and Fresnel Lens Replacement
1 ) Apply LENS-TAPE along the rear top edge of the Lenticular Screen.
2 ) Place the Fresnel Lens on top of the Lenticular Screen, and apply pressure along the top edge.
3 ) Place the screens in the screen frame and reinstall the cushions, top, bottom and side rails.
NOTE: The Lenticular Screen label must face the front and the Fresnel Lens label face the rear.
4 ) Reverse the Screen Removal Procedure and insert the screens in the Bezel.
1 ) Remove the Bezel screen assembly to access the speakers.
2 ) Remove 2 screws (A) and carefully slide the Speaker Assembly from the cabinet.
3 ) Disconnect the leads to the speaker.
4 ) Remove 4 screws (B) to remove the speaker from the speaker cover.
5 ) Reverse the procedure to install a replacement speaker.
1 ) The screen Bezel Assembly must be removed to access the PWBs-SBL (refer to the V38 Bezel Removal
Procedure).
2 ) Remove 2 screws (A) to remove the PWB-SBL assembly from the Bezel.
3 ) Remove 4 screws (B) to remove the PWB from the assembly.
4 ) Reverse the procedure to install a replacement PWB-SBL.
Many customer generated symptoms, intermittent symptoms or no symptom found can be resolved by using the
various Reset and Initialization options. Before visiting the customer’s home ask the customer 1st to try the SystemReset button on the control panel and if this does not resolve the issue, then they can perform an A/V Reset by
pressing the Guide + Format buttons on the front panel at the same time. Then, if necessary , perform a user level
Initialization by pressing MENU-123-ENTER with the remote. The customer should be made aware when settings
and/or options will be reset. For more information, see the chart below.
NOTE: During Initialization, the set will reboot. Wait until the Power
LED stops flashing before unplugging or powering ON the TV .
