Troubleshooting - Sony DAV-TZ130 Operating Instructions Manual

Precautions
On placement
 At high volume, over long periods of time,
the cabinet becomes hot to the touch. This
is not a malfunction. However, touching
the cabinet should be avoided. Do not place
the system in a confined space where
ventilation is poor as this may cause
overheating.
 Do not install the system near heat sources
such as radiators or air ducts, or in a place
subject to direct sunlight, excessive dust,
mechanical vibration, or shock.
 Do not install the system in an inclined
position. It is designed to be operated in a
horizontal position only.
 Do not place heavy objects on the system.
On operation
 If the system is brought directly from a cold
to a warm location, or is placed in a very
damp room, moisture may condense on the
lenses inside the unit. Should this occur,
the system may not operate properly. In
this case, remove the disc and leave the
system turned on for about half an hour
until the moisture evaporates.
 If anything falls into the cabinet, unplug
the unit and have it checked by qualified
personnel before operating it any further.
On cleaning
 Clean the cabinet, panel, and controls with
a soft cloth slightly moistened with a mild
detergent solution. Do not use any type of
abrasive pad, scouring powder, or solvent
such as alcohol or benzine.
If you have any questions or problems
concerning your system, please consult
your nearest Sony dealer.
On cleaning discs, disc/lens cleaners
 Do not use cleaning discs or disc/lens
cleaners (including wet or spray types).
These may cause the apparatus to
malfunction.
On your TV's color
IMPORTANT NOTICE
Caution: This system is capable of holding
a still video image or on-screen display
image on your television screen
indefinitely. If you leave the still video
image or on-screen display image
displayed on your TV for an extended
period of time you risk permanent
damage to your television screen.
Projection televisions are especially
susceptible to this.
On moving the system
Before moving the system, make sure that
there is no disc inserted, and remove the AC
power cord (mains lead) from the wall outlet
(mains).
On handling discs
 To keep the disc clean, handle the disc by
its edge. Do not touch the surface.
 Do not stick paper or tape on the disc.
 Do not expose the disc to direct sunlight or
heat sources such as hot air ducts, or leave
it in a car parked in direct sunlight as the
temperature may rise considerably inside
the car.
On cleaning discs
 Before playing, clean the disc with a
cleaning cloth.
Wipe the disc from the center out.
 Do not use solvents such as benzine,
thinner, commercially available cleaners, or
anti-static spray intended for vinyl LPs.

This system can only play back a standard
circular disc. Using neither standard nor
circular discs (e.g., card, heart, or star shape)
may cause a malfunction.
Do not use a disc that has a commercially
available accessory attached, such as a label
or ring.
On heat radiation
Due to the slim type of main unit design, you
may feel some heat on the top of the unit.
This is normal. Please consult your nearest
Sony dealer if you have any questions.
