When the power supply is being turned on, you may not remove this laser cautions label. If it removes, radiation of laser
may be received.
LASER BEAM CAUTION LABEL
PREPARATION OF SERVICING
Pickup Head consists of a laser diode that is very susceptible to external static electrocity.
Although it operates properly after replacement, if it was subject to electrostatic discharge during replacement,
its life might be shortened. When replacing, use a conductive mat, soldering iron with ground wire,etc. to
protect the laser diode f
rom damage by static electricity.
And also, the LSI and IC are same as above.
Soldering iron
with ground wire
or ceramic type
Ground conductive
wrist strap for body.
Conductive mat
The ground resistance
between the ground line
and the ground is less than 10
1M
SAFTY NOTICE
Plug the AC line cord directly into a 120V AC outlet (do
not use an isolation transformer for this check). Use an
AC voltmeter, having 5000 per volt or more sensitivity.
Connect a 1500 10W resistor,paralleled by a 0.15uF
150V AC capacitor between a k
nown good earth ground
(water pipe, conduit, etc.) and all exposed metal parts of
cabinet (antennas, handle bracket, metal cabinet
screwheads, metal overlays, control shafts, etc.).
SAFTY PRECAUTIONS
LEAKAGE CURRENT CHECK
Measure the AC voltage across the 1500 resistor.
The test must be conducted with the AC switch on and
then repeated with the AC switch off. The AC voltage
indicated by the meter may not exceed 0.3V.A reading
exceeding 0.3V indicates that a dangerous potential
exists, the fault must be located and corrected.
Repeat the above test with the DVD VIDEO PLAYER
power plug reversed.
NEVER RETURN A DVD VIDEO PLAYER TO THE
CUSTOMER WITHOUT TAKING NECESSARY
CORRECTIVE ACTION.
READING SHOULD NOT EXCEED 0.3V

The lightning flash with arrowhead symbol, within an
equilateral triangle, is intended to alert the user to 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 to the presence of important
operating and maintenance (servicing) instructions in the
literature accompanying the appliance.

1.1 No power when turned on
When the power is not turned on (front panel indicator does not light green) after pressing the
POWER button or the PLAY button, check the following items and repair the defective parts.
(1) Check the power supply cable
If the cable is not the supplied one, replace it with the supplied cable and turn on the power
again.
If the LED does not light after replacing, check the following items.
(If a cable other than the supplied one is used, the AC adapter may be damaged.)
(2) Check the AC adapter
If the AC adapter is not the supplied one, replace it with the supplied AC adapter and turn on
the power again.
If the LED does not light after replacing, check the following items.
(If an AC adapter other than the supplied one is used, the power board may be damaged.)
(3) Check the switch buttons
Check the following items.
a) Check the connector of the switch in the DVD player.
(If the connection is loose, reconnect the connector firmly.)
b) Replace the cover and turn on the power again.
(If the LED does not light after replacing, check the following items.)
(4) Check the power supply harness (MH95)
Check the connection of the 4-pin harness between the power IF board and the main board.
If the harness is not soldered fully, mount solder on it again. Then turn on the power again.
If the LED does not light after replacing, check the following items.
(5) Replace the power supply IF board
Check the soldered connection for the AC adapter jack. If a bad or poor solder connection is
found, replace the power supply IF board or PJ801. (The connector, which is on the power
board.)
If the LED does not light after replacing, check the following items.
(6) Replace the fuse
Replace F801 and F802 on the main board.
If the LED does not light after replacing, check the following items.
(7) Other than the above
Replace the main board.
(Replace the main board, for the trouble could be due to the damage on the main board.)
After replacing the main board, special adjustments in TOSHIBA are required. If not, readout of
DVD or CD media might not function properly.
1.2 The initial screen is not displayed on the LCD
If the initial screen is not displayed on the LCD, check the following items.
(1) Check the LED on the front
If the LED does not light, refer to 1.1.
(2) Check the back light
If the back light does not light up, separate the DVD player into the top assembly and bottom
assembly, and check the inverter harness MH94 (Check whether or not the connector side is
broken.), and check the connectors for defects.
a) If the connector harness is broken :
Replace the broken harness.
b) If the connector harness is not broken :
Remove the LCD cover and plate of the LCD unit and check the following.
· If the FL inverter harness is not inserted completely or disconnected, reconnect the
harness properly.
· Other than the above:
Replace the FL inverter or the LCD.
(3) Check the lighting of LCD
If the LCD does not light, separate the DVD player into the top assembly and bottom assembly,
and check the LCD harness MH96 (Check whether or not the connector side is broken.), and
check the connectors on the main board.
a) If the connector is broken :

insertion with slant or others).
If the LCD harness is not inserted completely or disconnected, reconnect the harness
properly.
d) Other than the above:
Replace the LCD module or the main board.
1.3 The DVD drive does not work
When the DVD drive does not work after the power is turned on, check the following items and
repair or replace the defective parts.
(1) Press the DISK cover switch (S102) at the center of the DVD player and turn on the
power. Then check whether or not the optical pick-up lens of the DVD drive light.
< CAUTION >
Do not stare in visible laser radiation at close when checking the optical pick-up lens.
· The optical pick-up lens lights dim :
It is caused by deterioration of the optical pick-up lens. Replace the DVD drive.
· The optical pick-up lens does not light :
Check the connection of the DVD-FFC to the main board and to the DVD drive.
Repair the connections and check the operation of the DVD drive again.
(2) Check whether or not the DVD-FFC is broken.
(If the DVD-FFC is broken, replace it.)
(3) Other than the above
Replace the DVD drive or the main board. [Perform pick short of the DVD drive when
replacing.]
After replacing the DVD drive or the main board, special adjustments in TOSHIBA are
required. If not, readout of DVD or CD media might not function properly.
Insert a DVD disk and turn on the power. Check whether or not the DVD drive works.
· The DVD drive does not work.
Adjust the DVD drive. If the drive does not work after the adjustment, the motor portion
of the DVD drive or the main board is defective. Replace it. After replacing the DVD
drive or the main board, special adjustments in TOSHIBA are required. If not, readout of
DVD or CD media might not function properly.
