1.2.1.1. 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.
1.2.1.2. 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.
1.2.1.3. 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.

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).
