SOURCE: The DVD player will not play anything. It says

Ok, this interesting. I don’t see this much. The region is a code that is set in the dvd player to limit the unit to playing dvd's for a specific country. It is a copyright protection that is built into a dvd player. USA is regon 1. DVD's can be made without region codes and these dvd's will play on and dvd player.

So to answer your question: Either the tv was bought in a foreign country, or the dvd's were bought in a foreign country.

You were the one to post the question little earlier. A region error is a strange error to get for a malfunction. But in any case it will be a fault with the decoder board / laser in the dvd player. These usually don't have firmware updates and are rom based so re-programming is not an option. The region error may also be cloaking the real problem. The more likely problem is that the dvd's laser pickup has failed. The first thing it tries to get is the region code, so if it cannot read this maybe that is why it is throwing you this error. Try to clean the lens, i don’t give that much hope but it is the only remedy other than repair that i can offer.

Invalid region When I put a disc in, I get this

This means that the region code on the disk (which determines where it may be played) does not match up with the region of your DVD drive.

Normally the region code can be changed, but only a limited number of times.

Try to make that if you buy a DVD online, it has the correct region code for your player

This may help

Unlock LG DVD

The following hack worked for my player. It works for most LG and Aiwa players too. To hack the player try this:
  • Power on player with no disc inserted and wait for "No Disc" message on screen
  • (using the remote) Press PAUSE
  • Press the numbers 314159 in order. (player should now show "COdE - -" the same as below)
  • Press the number of the region you desire ( 0 = any region, 1 = US&Canada etc.)
  • Press PAUSE
  • Power off the player for a few seconds..power back up and insert your DVD disc
