Servicing; Helpful Hints - Sanyo CE28WN5-B Instruction Manual

Servicing

Your television is fully transistorised and does not contain
any user serviceable components.
You must not remove the rear cover of the TV by yourself. The
apparatus is working with high voltages and could damage
objects or even endanger people. Leave all required repair
and service jobs to an authorised service technician. He will
exclusively use such spare parts that are complying with the
same safety standards as appliciable to the original parts.
The use of original spare parts can prevent fire, shock and
other hazards.
Unplug the television receiver from the wall outlet and refer
servicing to qualified service personnel under the following
conditions:
If the power cord or plug is damaged.
If liquid has been spilt into the television receiver.
If television receiver has been exposed to rain or water.
If the television receiver has been dropped or the cabinet has
been damaged.
If the television receiver exhibits a distinct change in performance.
If the television receiver does not operate normally by following the
operating instructions.
Adjust only those controls that are covered in the operating instructions
as improper adjustment of other controls may result in damage. This
will often require extensive work by a qualified technician to restore the
television receiver to normal operation.

The following faults are not caused by the receiver:

abnormal conditions can be reduced to
minimum by repositioning aerial or by
installing new one suited for your area.

appliances, car ignition systems, etc.
This should normally be a temporary
condition, but should this interference
persist, contact your dealer.
