1. SAFETY PRECAUTIONS
3
PDFcreated withpdfFactoryProtrialversion www.pdffactory.com

1.1. GENERALGUIDELINES
1. For continued safety, no modification of anycircuitshouldbe
attempted.
2. Disconnect AC Plug before disassembling thisunit.
3. Itisadvisableto use an isolation transformer inthe AC supply
before servicing.
4. When servicing, observe the original lead dress. Ifashort circuit
isfound, replace all parts which have been overheated or
damaged bythe short circuit.
5. After servicing, see to itthat all the protective devices such as
insulation barriers, insulation papers, shield, and isolation R-C
combinations etc. are properlyinstalled.
6. After servicing, be sure to restore the wires, leads, insulation
barriers, shields, etc.
7. After servicing, make the leakage current checks to prevent the
customer from being exposed to shock hazards.
Caution:
Use aseparate Isolation Transformer for thisunitwhen servicing.
1.2. LEAKAGECURRENTCHECK
1. Connect AC Plug to 120 voltor 240 voltAC outlet.
Donot use the ground prong of AC Plug. (See Fig. 1-2-1)
Donot use aisolation transformer for thischeck.
Fig. 1-2-1
2. Connect a1.5Kohms, 10 watts resistor, inparallel with a0.15 F
capacitor, between each exposed metallicpart on the set and a
good earth ground. (See Fig. 1-2-2)
Fig. 1-2-2
4
PDFcreated withpdfFactoryProtrialversion www.pdffactory.com

3. Use an AC voltmeter, with 1000 ohms/voltor more sensitivity, to
measure the potential across the resistor.
4. Check each exposed metallicpart, and measure the voltage at
each point.
5. Reverse the AC plug inthe AC outlet and repeat each of the above
measurements.
6. The potential at anypoint shouldnot exceed 1.125 voltRMS. A
leakage current tester (Simpson Model 229 equivalent) maybe
used to make the hot checks, leakage current must not exceed
0.75 milliamp. Incase ameasurement isoutside of the
limitsspecified, there isapossibilityof shock hazard, and the LCD
Projector shouldbe repaired and rechecked before itisreturned
to the customer.
1.3. UV-PRECAUTION
1. Besure to disconnect the AC Plug when replacing the lamp.
2. Since the lamp reaches averyhigh temperature during its
operation, waituntil ithas completelycooled off when replacing
the Lamp Unit.
3. The lamp emits small amounts of UV-Radiation.
Avoiddirect-eyecontact. Fig. 1-3-1

2. OPERATION GUIDE
Note:
-Atthisservice manual, itmentions onlythe Operating Instructions
of PT-L759Uas the representative of PT-L759U, PT-L759E and PT-
L759A.
-Because some pages inthe user instruction manual are used for
thischapter (page 5through 50 inthisservice manual)without
change, note that the page numbers showninthe sentences of
thischapter are those of the user instruction manual.
3. SERVICE CAUTIONS AND NOTES
3.1. SERVICEPOSITION
The position showninFig. 3-1-1 is usedforchecking, adjusting and replacing parts.
Extension Cable (LSUA0024) is necessaryforservicing.
Fig. 3-1-1
1. Inthe order described inthe "4.2. DisassemblyMethod of Cabinet
Parts" of 4. Disassembly/AssemblyProcedures, remove the Top
Cover Ass'y.
2. Remove 7screws(F) and 2screws(G)as showninFig. 4-2-6.
3. Disconnect connectors P3501, P3502, P3503 and P4001 on the
MainC.B.A.
4. Connect Extension Cables as follows:
A. Connect Extension Cable(36 pin) between P3501 on the Main
C.B.A. and LCD Red Unit.a) Connect Extension Cable(36 pin)
between P3501 on the MainC.B.A. and LCD Red Unit.
