Sorry--You will need resources to fix this one. STK392-110 IC's need to be replaced,afterwards convergence alignment in servicer mode may be needed.

Picture has shadows with different colors (red, yellow, green)

Sounds like the convergence needs adjustment. You can do this through the menu-follow the on screen instructions. The idea is to line up the red, green, & blue.

Blue and red overlap shadowing

convergence ic's are your culprit. they are responsible for aligning the 3 colors your tv projects onto your screen..

Picture has a blue shadow

Seems convergence out IC is fried in TV so it gives blue shadow.

Check out Convergence Out IC which you need to replace in TV, if you have enough experience of repair of big TV, necessary tools and know basic electronics.

it sounds like your blue convergence ic is getting weak you need to replace the ic's STK392-110 and you should replace both because when 1 is bad the other will go real soon. They are inexspensive at the sight I posted and you will also get free tech online support if you purchase them there.

Hi! Guy,
I don't think your problem was caused by lightning. It sound like defective convergence ICs. This must be checked and verified by a qualified service tech.

Blue and red shadows on screen

This sounds like one of the convergence IC's has cracked loose or burned out, and should be replaced and realigned by someone with experience.
