?To know fast whether inverter is functioning, visually check
if the backlights are ?on? by looking at the back of the LCD
panel. Some bright spots can be seen on the side. Other
way to tell whether the backlight is working is to switch the
set to AV mode. The front of the screen had some kind of
?fogged? effect.
Note: when one of the backlight connectors has loosened,
the inverter circuit will be shut down.
?If the supply to the LCD panel is OK (likewise for backlight
supply), but no data signals (example: signals on
connector 1506) supplied from Scaler to LCD panel, you
will notice that the LCD screen will shown full screen in
sequential of BLUE, GREEN, RED, BLANK, dark-GREY,
light-GREY and WHITE repeatedly. It means LCD panel is
in good condition. The fault lies in the Scaler board |
