General
To avoid inverter unit-C/D trouble (carbonization of PWB) when a particular backlight tube broke, we change
the inverter unit-C/D in order to improve spacing between foil patterns.
Servicing
When servicing any unit regardless of symptoms, please change the inverter unit-C/D together.
• Change Inverter unit-C from RUNTKA273WJZZ(WJTZ) to RUNTKA273WJN1(WJT1).
• Change Inverter unit-D from RUNTKA274WJZZ(WJTZ) to RUNTKA274WJN1(WJT1).
