Thanks for your solution. This is a problem with color wheel. I could not fix it by myself, so my friend will try to fix it next week.

Sounds like you have a bad color wheel assembly which is located in your light engine assembly.

Tv is making a loud buzzing noise and the picture is all funny ie colurs are out and pixelated

your keeping a part that is warming up and shuts down your shutdown that protects the tv from burning up... cooler... to find this you might need a hair dryer or a can of freeze mist.
I believe the left side is your high-voltage section.
you can also let it warm-up without the fan .. let it shut down and feel parts with set unplugged to see what is running hot.

Loud humming or buzzing when set is in operation

Does the picture gets distorted in any way when you hear the buzzing noise?
I would suggest to check all the cooling fans for proper operation.
