X-RADIATION PRECAUTION
The primary source of X-RADIATION in television receiver is the picture tube. The picture tube is specially con-
structedto limit X-RADIATION emissions. Forcontinued X-RADIATION protection, the replacement tube mustbe
thesame typeas the original including suffix letter. Excessive high voltage may produce potentially hazardous
-RADIATION.TO avoid such hazards, the high voltage must be maintained within specified limit. Refer tothisser-
vice manual, high voltage adjustment for specific high voltage limit. lf high voltage exceeds specified limits, take
necessary corrective action.Carefully followthe instructions for+Bl voltpowersupply adjustment, and high volt-
age check to maintain the high voltage within the specified limits.
PRODUCT SAFETY NOTICE
Product safety should be considered when acomponent replacement is made in any area of areceiver.
Components indicated by mark ~in the parts list and the schematic diagram designate components in which
safety can be of special significance. It is particularly recommended that only parts designated on the parts list
in this manual be used for component replacement designated by mark ~.No deviations from resistance
wattage or voltage ratings may be made for replacement items designated by mark ~.

Protection Circuit
This TV set has abuilt-in power supply protection circuit.
It is provided to protect the TV set in case of apower supply circuit malfunctions. When something abnormality
occurs during TV reception, the TV set goes to the stand-by mode.
When an abnormality occurs during TV reception, it causes pin 24 of the CPU to go continually Low(less than
0.75V) for about one second. The CPU detects that this has occurred and outputs the signal from pin 15 to
switch off the power supply lines.
■Releasing the protective ch’cuitand restoring power supply
To release the protective circuit and restore power supply, turn the power to the TV set OFF and then ON again
via either the main power switch or the ON-OFF button on the remote control. This will work only if the power
supply trouble was temporary. If there is permanent trouble such as adamaged circuit, power cannot be
restored and the circuit will have to be repaired.

Service Adjustments with Replacing Memory IC(IC802)
Note: The CPU (IC801 )and memory IC (IC802) store the service adjustments data and controls data for each circuit.
When the Memory IC(IC802) is replaced, some of the service adjustments should be readjusted to obtain the
best performance. The necessary service adjustments are carried out by using the RC handset. Please set
up the TV set with following steps [1] to [3].
[1] Initializing Procedure
1.Put anew memory IC.
2. Turn on the TV set.
3. Press and hold the ~V/AV] button on the TV set more than 2seconds. The following picture appears on the screen.
