<CONTENTS>
Take the following measures with regard to complaints that the powershuts off or cannot be
turned on in relation to the model above.
<COUNTERMEASURE>
1. Check the condition of the TV set(whether it is in the protection mode against a power supply
error) by the following steps a e.∼
a. Check that the power cannot beturned on from either the power button on the TV set or the
remote controller (stand-by: a red LED goes on).
b. Press the "TEST" key on the jig remotecontroller to see if the power comes on (if it does not
come on, the microprocessor may be broken).
If the protection function is on duringpower supply error detection, pressing the "TEST" key
makes the LED flash in green and an AGING display is shown.
Pressing the keys on the remote controller in the following order instead of pressingthe
"TEST" key will also bring up the AGING display.
"ENTER" "AV MODE" "SLEEP" "MENU" "POWER"
c. Once the AGING display is shown, pressthe "TEST" key to erase the AGING display and
disconnect the power supply cord.
If you have had no problem in operation up to this point, there is no problem with the∗microprocessor and the EEPROM.
d. Connect the power supply cord.
Check that the power is turned on by pressing the "Power" button on the TV set / remote
controller (complete the procedureby performing steps 2 and 3 below).
e. If the TV-set is still in stand-by status, the protection functioni s on duringdetecting an error,
so check if there is a problem with the power supply system.
2. Check the R617 resistance (when the resistance is excessive or OPEN, a power supply error is
detected). SerialWhen R617 is 1/8 W, change it to 1/4 W (this has already been changed for models with
or later).No.S 0C∗∗∗∗ ∗∗∗∗∗
When replacing the EEPROM (IC3), refer to the"Description" in the table below to select an∗
appropriate EEPROM. Different models/specifications require different EEPROMs.
Refer to the NOTE below.
NOTE
Turning on the power after replacing EEPROM activatesdata writing between
microcomputer and EEPROM. (The writing takes approximately1 minute.)
After completion of data writing, power is automatically turnedon.(Do not disconnect the AC
cable while data is being written.)
After replacing EEPROM, readjust and verify electrical adjustmentto the service manual.
