One of the primary reasons your LG 47LH30 TV may not turn on is a power supply problem. Check if the power cord is securely plugged into both the TV and the electrical outlet. Ensure that the outlet is functioning correctly by plugging in another device. If the outlet works, but your TV still won’t turn on, try using a different power cord or adapter to rule out any potential issues with the power supply.

If the TV still doesn’t respond, try using the power button on the TV itself to eliminate the possibility of a faulty remote control.
3. Software Issues
Software glitches can sometimes prevent your LG 47LH30 TV from turning on. To troubleshoot this, unplug the TV from the power source and wait for a few minutes.
