Have you tried connecting different known working signal sources e.g. dvd player, TV antenna etc or different inputs e.g RF input, HDMI, AV etc to see if you get a picture?
You don't unplug and hold the remote control unit's power button for 1 minute, you unplug and then press and hold the TV's power on/off button (if it has one) for 1 minute
Hi @killerdenson
What is the model number of the TV?
Is the sound heard when the TV is on?
