Sounds like it's in a service burn-in mode. LGs need a service remote to de-activate. Probably easy for a local LG shop.

Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.
For example, 3 flashes, then 7 flashes = 37.
Here are the error codes, and the corresponding problem:
12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected

I gotta a green screen


It is possible that you have a shorted green CRT, you can remove the front speaker cover, and you will fine a focus block, and if you turn down the green screen voltage, very slowly, the green should turn down. if not then the gun (CRT) will have to be replace, If it does turn down, then go into the menu and turn the color are the way down and that should give you a black and white picture. If it is not black and white. adjust the red, blue, and green screen voltages until you receive a good black and white picture. Turn slowly they are touchy, and if turn to high, you will get retrace lines and the TV will shut down.

The colour on my TV is a reddish colour. Have tried the colour adjustment. Skin colours in particular.


simple. easy. you have 3 screen adjustments. red green blue. turn color all the way down. you should then get just a black and white picture, but in your case, it will still be reddish. behind the speaker grill is an access panel for screen adjustment. remove speaker grill. remove access panel. you will see a block assembly roughly 6 inches square with 6 knobs on it. 3 are for screen, 3 are for focus. adjust until you have a black and white picture. then go into menu and turn your color back up. enjoy!

There is a green tint to my screen. Seems to be more evident in dark shows and on shadows.


Pull the front speaker grille off and remove the access panel. In the customer menu turn the color off so you have a black and white picture. get a flashlight and adjust the screen controls for the red, green and blue tubes until you get a nice black and white picture. then turn the color back up.
