1) Following voltage lines on the Main P.C.B. is over voltage or over
current.
• DT+9V line
• DT+5V line
• SW+3.3V line
• SW+2.5V line
• DT+9V line
• DT+5V line
• SW+3.3V line
• SW+2.5V line
Possible Solution
Replace the TV Unit (Main P.C.B).
2) Cooling Fan (Fan 1, Fan 2 and/or Fan 3)
malfunction.
Possible Solution
3) DT+5V line on the Main P.C.B. error.
Possible Solution
1. Replace the TV Unit (Main P.C.B.)
2. If still NG, replace the Digital Tuner P.C.B.
3. If still NG, replace the Power P.C.B.
2. If still NG, replace the Digital Tuner P.C.B.
3. If still NG, replace the Power P.C.B.
4) Communication error I2C SERIAL DATA for between IC6001 (Pin 85) and IC5001 (Pin B22) on the Main P.C.B.
Possible Solution
Replace the TV Unit (Main P.C.B.).
5) The temperature sensor (R2821) on the
Thermistor 2 P.C.B. on the Lamp Top Panel is short or open.
Possible Solution
Possible Solution
1. Remove CN2301 connector on the LCD Drive
P.C.B. and check if the resistance between pin1 and pin2 of P2821 on the
Thermistor 2 P.C.B. is 5 k 1 M .
2. If still NG, replace the Temperature Sensor (R2821) on the Thermistor 2 P.C.B.
3. If still NG, replace the Projection Unit (LCD Drive P.C.B.).
4. If still NG, replace the TV Unit (Main P.C.B).
2. If still NG, replace the Temperature Sensor (R2821) on the Thermistor 2 P.C.B.
3. If still NG, replace the Projection Unit (LCD Drive P.C.B.).
4. If still NG, replace the TV Unit (Main P.C.B).
6) It indicates when the temperature detected by
the Temperature Sensor (R2821) on Thermistor 2 P.C.B. exceeds 105 ˚C (221 ˚F).
1. The surrounding temperature of the place of use may be too high.
2. The vents on the rear may be blocked.
1. The surrounding temperature of the place of use may be too high.
2. The vents on the rear may be blocked.
Possible Solution
1. Relocate the unit to a proper location.
• Do not place in direct sunlight and other sources of direct heat.
• Do not place the unit in humid or dusty location, or areas exposed to smoke or steam.
(surrounding temperature should be between 0 ˚C (32 ˚F) and 35 ˚C (95 ˚F) and humidity
should be between 20 % and 80 % (with no condensation).)
• The vents are not blocked. It is recommended that a gap of at least 10 cm is left all around the unit even when it is placed inside a cabinet or between shelves.
2. Check if the fans are operating properly.
• Do not place in direct sunlight and other sources of direct heat.
• Do not place the unit in humid or dusty location, or areas exposed to smoke or steam.
(surrounding temperature should be between 0 ˚C (32 ˚F) and 35 ˚C (95 ˚F) and humidity
should be between 20 % and 80 % (with no condensation).)
• The vents are not blocked. It is recommended that a gap of at least 10 cm is left all around the unit even when it is placed inside a cabinet or between shelves.
2. Check if the fans are operating properly.
7) Clogged Air Filter of the Fan Case Unit.
Possible Solution
1. Clean the Air Filters on the Projection Unit.
2. If still NG, replace the Projection Unit.
3. If still NG, replace the TV Unit (Main P.C.B.).
3. If still NG, replace the TV Unit (Main P.C.B.).
8) The Lamp is defective (short of the Lamp).
Possible Solution
1. Wait until the Lamp is cooled off and try to
turn the power back on. If same error LED indication continues, remove the Lamp
and visually inspect it. If it is cracked, it must be replaced. If the Lamp is
OK, replace the Power P.C.B.
9) When the Iris Mechanism fails to reach the
objective angle of +/- 2˚ in two consective seconds.
Possible Solution
Replace the Projection Unit
10) When power is turned on, the Iris Mechanism performs
calibration to incorporate variations detected by the Hall Sensor. A maximum
current (+) and (-) is supplied to the Motor and the Mechanism moves to the
full-open/ full-close position. An error occurs when this angle is measured by the Hall
Sensor and full-open/ full-close is not reached, or when the angle difference
is outside the controllable range.
Possible Solution
Replace the Projection Unit
11) Mis-installed Lamp Cover (the Lamp cover is
open).
Possible Solution
1. Install the Lamp Cover Unit properly.
2. If still NG, check and replace the Cover Switch P.C.B.
3. If still NG, replace the TV Unit (Main P.C.B.).
2. If still NG, check and replace the Cover Switch P.C.B.
3. If still NG, replace the TV Unit (Main P.C.B.).
12)
1. +17V line on the LCD Drive P.C.B. error.
2. +9V line on the LCD Drive P.C.B. error.
3. +5V line on the LCD Drive P.C.B. error
2. +9V line on the LCD Drive P.C.B. error.
3. +5V line on the LCD Drive P.C.B. error
Possible Solution
1. Replace the Projection Unit (LCD Drive
P.C.B.).
2. If still NG, replace the TV Unit (Main P.C.B.).
2. If still NG, replace the TV Unit (Main P.C.B.).
