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fromdamagebystaticelectricity.

Andalso,theLSIandICaresameasabove.

SAFTY NOTICE

LEAKAGE CURRENT CHECK

SAFTY PRECAUTIONS

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 known 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.).

READING SHOULD NOT EXCEED 0.3V

DVD VIDEO PLAYER

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.

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) 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) Chec k the connector of the switch in the DVD player.

(If the connection is loose, reconnect the connector firmly.)

b) Repl ace 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 :

(1) Press the DISK cover switch (S102) at the center of the DVD player and turn on the

power. Then check whet her 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 :
