1. General Section 1.1. Cautions/Warnings

1.1.1. Product Safety Notice Parts marked with the symbol in the schematic diagram have critical characteristics. Use ONLY replacement pares recommended by the manufacturer. It is recommended that the unit be operated from a suitable DC supply or batteries during initial check out procedures.

1.1.2. Leakage Current Check/Resistance Check

Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to insulated resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power cord is less than 240 K ohms, the unit is defective.

WARNING: DO NOT return the unit to the customer until the problem or located and corrected.

1.2. Safe Warnings 1.2.1. Protection of Eyes from Laser Beam

To protect eyes from invisible laser beam during servicing

DO NOT LOOK AT THE LASER BEAM

1.2.2. Laser Caution CAUTION

Adjusting the knobs, switches, and controls, etc. or taking actions not specified herein may result in a harmful emission of laser beams. This CD Changer must be adjusted and repaired only by qualified service personnel. Laser symbol:

THIS IS COMPACT DISC PLAYER IS CLASSIFIED AS A CLASS 1 LASER PRODUCT.

THE LASS 1 LASER PRODUCT LABEL IS LOCATED ON THE REAR EXTERIOR.

1.3. Precautions 1.3.1. ESD Precautions in Repairing

1.3.1.1. Do not apply excessive pressure on the mechanical parts (moving pares), including the Pickup Block, as extremely high mechanical precision or required in these parts.

1.3.1.2. When soldering the microprocessor and signal processing IC’s, use a ceramic soldering iron or a soldering iron whose metal part is grounded since they are not resistant to static electricity.

1.3.1.3. When removing the solder or soldering the laser shorting lands for the Pickup Block, use a ceramic soldering iron or a soldering iron whose metal part is grounded since the laser diode or not resistant to static electricity.

1.3.2. DVD Loading Unit Precautions when handling the Mechanism Block

1.3.2.1. Do not loosen any screws in the Pickup Block. 1.3.2.2. Do not adjust any screws in the Mechanism Block except

for “Tilt Adjust Screws”, as they are adjusted precisely at the factory.

1.3.2.3. Replacement of the Pickup Block is impossible. Always replace the Traverse Ass’y when the Pickup Block needed to be replaced. Do not touch the lens or lens holder of the Pickup Block.

1.3.2.4. The Guide Rails of the Pickup Block are greased. Take care when handing.

1.3.2.5. When you try to slide the Pickup Block, do not press or pull it directly. Always turn the dive gears with your fingers.

1.3.2.6. Be sure that the anti-slipping rubber on the turntable or clean. If there is dust or it is greasy, clean the part with the liquid that contains 50% each of alcohol and water.

1.3.2.7. When removing the Mechanism P.C.B. Ass’y, you need to short-circuit the laser diode shorting lands beforehand.

1.4. Software Upgrade You can upgrade DVD Player using the software we provide as following step:

― Creating a software upgrade CD ― Use only a new CD-R/CD-RW(not an erased one). ― Give the CD a name of your choice(e.g. version and unit name). ― Burn the unpacked documents on the CD-R/CD-RW. ― The root directory(uppermost level) of the software upgrade CD

Attention: If a failure should occur during the software upgrade (e.g. a mains failure), it may happen that the units function and a restart of the upgrade function are no longer possible. If this should be the case, you must replace the intergraded FLASH ICs with preprogrammed ICs (see corresponding spare parts list). ─ Insert the upgrade CD (see corresponding spare parts list) and observe the hints on the

display and on the screen of the TV set. ─ Carry out an initialization of the set. Displaying the Software Version Number ― Press one after the other the “STOP” and “EJECT” buttons on the unit. ― Press the“OSD” with the remote control. ― Using the cursor buttons on the remote control, select the software version “MICRO

Version” or “CUSTOMER VERSION” .The respective software version number then is displayed

3.2. Read Disc Trouble Service Flow Chart

Read disc problem in a DVD player is a very complicated issue that may involve complex issues. This problem is not only relation to the electronic circuit, but also very much relation to the operation environment. DVD loading unit is a very complicate part that contains big number of ESD components, which require specific equipment, tools and technique to repair; in general, service technician is not suggested to disassemble the DVD loading unit. It is suggest proving the trouble and replacing the complete DVD loading unit, instead of repairing the DVD loading unit in local workshop. It is suggested to prove the faulty of a DVD loading unit by replacement by a good DVD loading unit. Before checking the "NO Disc" Trouble, ensure excluding the following possibilities:

The test disc is damage. AC power supply voltage dropped below the minimum required

level. DVD disc region code and color system is not matching to the DVD player or system setting. Moisture condensed inside the unit. (Power on the unit, without disc loaded, for 1/2 to 2 hours).
