If i open teletext the screen is black and shows only the four buttens red green yellow and blou
You should press the home button of your teletext page usually its 100
or you could press one of the four colored buttons o your remote control unit so it will reset to the home page of the teletext
(a black page mostly says that teletext isn't available to the specific channel )

The Lg lcd was srtruck by a remote and now looks like a small crak on the inside towards the bottom right hand corner and there is no picture but audio does work
SOURCE: LG 42'' TV has no sound but great picture. How do I get the sound?
You shouldn't need anything plugged into the accessory jacks to get local sound from your set.
Go through the main setup menu and check audio settings; they may be set to turn off the internal speakers to send the sound to a home theatre that you apparently don't have.
Most sets have that as a selection and supply L-R audio for an external system and mute the internal speakers.
FYI: The three connectors you mention are coded as follows:
Red - right channel audio
White - left channel audio
Yellow - composite video (contains synchronization signals and video)
These may be input connectors (for external VCR/DVD decks) so check your owner's guide to verify.
SOURCE: My wii connection is black and white
You are connecting it into the wrong input. The Wii comes with a RCA cables that should go into the Video (composite) input that has yellow, red, and white. The component input will not work with the RCA cable input. Plug your Wii into Video1 and you should get the right colors. There should be another HDMI on the side of your TV, there are inputs located both on the back and side of the TV for your convience.

This is a common fault on all LG sets with few people offering any solutions. I can offer a solution that could remove 95% if not 100% of the dots.
Remove the back of the set, there are about 40 screws. On the left hand side on a circuit board you will see 3 or 4 blue plastic boxes with yellow screw adjusters in them. The only 2 you are interested in are VR3 "setup" and VR2 "setdn". Mark the location with a marker pen so that you know where the factory settings were. Then turn VR3 fully clockwise. If this does not get rid completely do the same with VR2. This worked for me today, I was about to throw the TV away but I now have a 95% improved screen, sharper and more vibrant picture and saved hundreds. Hope it works.

A black line down the middle of the TV can be a few things. You plasma panel might be bad your buffer on that location of the screen might be bad or your logic board might be bad. Teh only way to find out is by replacing the parts , You can get parts at www.interliquidparts.com

Managed to get old school text working on 2018 LG tv.
1) disable HbbTV (settings / all settings / programmes / HbbTV/ Auto Start OFF).
2) power off tv (via tv full off, not on remote for standby).
3) turn on tv. Put on BBC either SD or HD channel. Wait 10 seconds or so for the green restart programme pop up - indicates text now ready.
4) press text.
5) if you press the Red Button it all stops working until you put TV in standby and restart it.
6) to get red button functionality back, turn HbbTV back on. Turn off TV power at TV. Restart and you now have red button functions, but no old school teletext.
