could be a problem in the inverter board and the backlight lamp of the
monitor .
The lamp is a cold cathode bulb it requires a high voltage
supply from the inverter board in order to light up. Like any other
bulb this lamp has a limited life span more or less 2 years of
continues lit.
The inverter board is a high voltage board the power
input of this board is 24volts DC and the output is 200volts AC.The
terminal input of this board or connectors must be check because of
high voltage Corrosion and loose connections always happen that leads
to the mal function of the display or screen failure just like what
happen to your TV.
Backlight lamp is installed at the top and
bottom of the screen you need to open the back cover of your TV to
check up the lamp.(make sure to unplug the TV before proceeding)

Hello, have you tried unplugging the TV from the AC outlet and reconnecting, most times it will correct a "system lockup". If this doesn't correct the problem, suspect a bad infrared preamp board, usually located right where the customer keys are located.
Acer PD116Pd Projector no powerup .
Hi,
Please start by switching the outlet that you use to power your projector. If you're not currently plugging the projector into an outlet but using a power strip, you can test that the power strip is still functioning by using it with other items. Thank you.
