Hi D
Sounds like the Switch Mode Power Supply is failing to Power Up.
Often Caused by Bad Electrolytic Capacitors inside the Power Supply Circuitry.
Probably a replaceable PCB Module.
Take it in to your dealer or Electronics technician.

Cheers

Sounds like a power pack issue. Might be the switch mode transistor not working correctly. Either try repairing it or take it to a local tv repair centre

Inverters use square wave voltage, which tends to stifle digital circuits. Leaving something stuck, or not working. Sure, the inverter will work for awhile, but then the rigid square wave eventually causes problems.

Pull the plug out of the socket.

Hi,
When a TV is stuck in standby mode often means that there is a problem with its power supply or even in the horizontal output circuitry. May be a component with short-circuit in the RGB output driven by the flyback transformer or a rectifier diode in the power supply output.
I hope having helped you.

My classroom TV seems to be stuck in standby mode. Blue light is on but TV won't turn on either by push button or remote.
