    I have a similar problem with an Akai aswell but after a while of use the picture starts jumping. Does this mean I have a board over heating also? And is my test the same? If it is what do you do when you find the problem board?

Try putting a fan on the back of the tv to see if it is getting better. If it does then you probally have a board that is overheating. If that is the case then CAREFULLY !!! remove the back and place where you can turn on and safely access the open back NO TOUCHING STUFF !!! Mabey lay it face down on a glass table or lay it on a table with 25% hanging over the edge to see the screen. Then take a COLD blow dryer and blow it on the boards to find out which one makes it get better. If one does then it will probally be your problem board. Make extremely sure that is the one before removing it by blowing from all angles on the boards around it without air hitting the suposed problem board. Then try a little hot air to see if that starts the problem on that board so you can be sure. Of course check the surrounding and offending board several times to be sure before removing.

Contact your LG dealer to arrange a service call & have the software version updated, an older software may be present in the TV which can give a white screen start up problem

Your green gun in our tv is misagligned/out of focus. Your tv uses red, green and blue guns that layer in different shades and mix to create the different colors. Your green is a little off so the colors aren't mixing right which explains the green haze and the shadows. A tv repair man can fix this problem pretty easily and it isnt expenisve.
