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.

AC VOLTMETER

(5000 per volt or more sensitivity)

Good earth ground

1500 10W

such as a water pipe, conduit, etc.

AC OUTLET

0.15uF 150V AC

Test all exposed metal. Voltmeter Hook-up for Leakage Current Check

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) Insert a DVD disk, and turn on the power. Then check the LCD screen or use an external

display. The message “Loading” is not displayed or the operation stop s at the message

“Loading”.

Since the DVD drive or the main board is defective, replace it in the following order and check the operation. [Perform pick short of the DVD drive when replacing.]

1) Replace the DVD drive

2) Replace the main board 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.

The message “PLEASE CHECK DISK” is displayed.

Check the DVD disk for fingerprints, dirt etc. If the DVD disk has no problem, then check the following items.

1) Check the DVD-FFC If connections are loose, reconnect the DVD-FFC firmly. If the DVD-FFC is damaged, replace it with new one.

3. Disassembling and Reassembling Procedure

3.1 Disassembling and reassembling Procedure Chart

This section explains how to disassemble SD-P2600, replace parts and reassemble. It may not be necessary to remove all the parts in order to replace one. The chart below is a guide to which parts need to be removed in order to remove others. You can see how to disassemble and reassemble by clicking the icon on the chart. Before disassembling, take proper measures against electric static. The following movies show the procedure for assembling/disassembling of SD-P2500 as the procedure for SD-P2600.

It is because there are only few differences on disassembling/reassembling procedure and its appearance between SD-P2500 and SD-P2600. When the movie includes the changes in SDP2600, “*change” mark is added in the title box. For the details on the changes, refer to the “3.2 Changes in SD-P2600”. Start with removing the battery or disconnecting the AC adapter. Please install Apple Quick Time 4 or more for seeing the movies. When you stop the movie halfway, press Esc key.

order as shown in the picture.

Page 11

4. Inspection after Disassembling and Reassembling Note: Be careful not to make any scratches and dirt while you are working.

1. Check the power-on function

Press the power switch and make sure that the power is turned on.

2. Check the switches

Press each switch and make sure the switch is functioning properly as described in User’s Manual. Check all of the switches. Make sure the switch unit and main board are connected properly. The switch unit might be broken if the cable is inserted with slant or insertion/withdrawal of the cable is repeated.

3. Check the DVD replay (for single-layer disk)

Replay a DVD disk (single-layer disk) and check the output of sound and headphone. If pick short of the DVD drive is not removed, the DVD disk might not be replayed.

4. Check the DVD replay (for dual-layer disk)

Replay a DVD disk (dual-layer disk) and check the operation. If the DVD drive or the main board is not adjusted after replacing, the DVD disk might not be replayed.

5. Check the sound of CD-RW

Play a CD-RW or CD-R and check the sound. If pick short of the DVD drive is not removed, the CDRW or CD-R might not be played.

6. Checking the power-off function

Turn off the SD-P2600.

7. Appearance check

If you find any dirt or stain, wipe them with soft cloth.
