Check the back light lamp, D753, Q754, D757 and
their peripheral parts as well as pin (42) of IC2001.
Note:
This model is equipped with the lamp error detection function
that detects the current flowing into the fluorescent lamp and
protects the backlight lamp drive circuit.
If a lamp error is detected, the microprocessor interrupts the
unit and the ERROR NO RESET setting will go up.
When the ERROR NO RESET setting has reached "5", the
microprocessor turns and keeps off the unit's power. To
resume the power, take the above procedure to clear the
ERROR NO RESET setting.
