Not likely to be a do it yourself repair so best advice would be have a shop look at it--power supply or main board are most likely.

Horizontall lines appear on the screen on booting screen gets discoloured for a short while


RUN the LCD BIST test D+Power button at boot, see if you get 4 solid colored screens
If you do then the video processor is failing. This means replacing the motherboard.
If issue occurs during the BIST, then the LCD is failing and LCD will need replacement.

Try hot soapy water, since a flat screen TV should be glass.

Green Screen - LG 42PX5D


hello, seems to be panel trouble, plasma and lcd main panels are not fixable, the color green isnt a good sign or it is a symptom of the panel being bad,
i know its a bad diagnosis but this is true with this color on a panel.
if it is a worth while set and you want to restore it theres few options one is replacement trough your waranty

the another is having the screen replaced by a service center this is to costly and rarely done by them they would advise you to get another set. at a retail price a screen replacement is as much or even more than the tv itself.

finally you may search online listings for a servicable tv same model and exchange the parts .
the third option is the best if your waranty is expired.

good luck hope this helps

happy holidays.

Tv discolouration


It sounds like your problem is magnetisation of the crt. Try to switch it on and off for 3 times: on for 1 minute, off for 3minutes, on for 2minutes and off for 5minutes. Then switch on and see if the discolouration dissappeares. IF not, then a technician needs to check the internal degauss circuits.

CRT discoloured


If it's a deguass problem, you can glue some very small magnets to the sides of the crt tube itself, it could be the shadow mask, inside the monitor, and if it is then nothing will fix it, if you can get a deguass coil from somewhere that would tell the story real quickly
