REPLACEMENT OF MEMORY IC’s
1. Memory IC
This TV uses memory ICs (EEP-ROM IC). In the
memory ICs, there is memorized data for
correctly operating the video and deflection
circuits. When replacing memory IC’s, be sure to
use IC’s written with the initial values of data.
2. Procedure for replacing memory IC’s
Procedure
1) Power off
Switch the power oft and unplug the power code
from the outlet.
2) Replacing the memory IC
Be sure to use memory IC’s written with the
initial data values.
3) Power on
Plug the power code into the outlet and switch
the power on.
4) Check and set SYSTEM CONSTANT SET
1) Press the INFORMATION key and the MUTE
key of the REMOTE CONTROL UNIT
simultaneously.
2) The SERVICE MENU screen shown in Fig. 1
will be displayed.
3) While the SERVICE MENU is displayed,
press the INFORMATION key and MUTE key
simultaneously, and the SYSTEM CONSTANT
SET screen shown in Fig. 2 will be displayed.
4) Check the setting value of the SYSTEM
CONSTANT SET shown in Table 1. If the
value is different, select the setting item with
the FUNCTION UP/DOWN key, and set the
correct value with the FUNCTION -/+ key.
5) Press the MENU key to memorize the setting
value.
6) Press the INFORMATION key twice, and
return to the normal screen.
5) Setting of receive channels.
Set the receive channels. For setting, refer to
the OPERATING INSTRUCTIONS.
