If the TV does not power up then primarily verify that the power is supplied OK. If there is no light at all on the front it could be a failure of an internal fuse.

This would entail dis-mantling using safe procedures and checking for blown fuses A broken fuse could point to a minor failure but a blackened fuse means a large failure which needs investigating before going any further.

Take a look at the troubleshooting guide here:

https://www.manualslib.com/manual/1536912/Lg-55lw5600.html

It is most likely a failure of the power board if both sound and picture are not there. If you are unsure as to how to proceed then I suggest contacting a service engineer for advice.

Hope that helps.
