Why my TV is can't turn on

I’m sorry to hear that your LG TV 42lc7d won’t turn on. According to a post on TechRandm, you can try the following steps to resolve the issue:

1. Unplug your TV from the wall and wait for 60 seconds.
2. Press and hold the power button for 30 seconds.
3. Plug the TV back in and turn it on.

This process discharges all the capacitors and drains the circuit of any residual charges, which can help your TV reboot fresh

If this doesn’t help, you can try checking if the standby light is on when the TV is off. If it’s not, check the power cord. If none of these solutions work, it might be worth considering taking your TV to a professional repair service.

I hope this helps!
