How do i remove the green haze

one of two issues are possible here:

Model indicated has a convergence circuit= colors are skewed or even 3d looking is convergence problem. Set has Akai name but is made by Samsung--if a convergence issue can be a do it yourself repair.

I can explain what is needed if that is the problem (see some attached photos).

The other issue seen is if on a black and white picture (color turned off) stand back and look at the screen= is it yellow looking or gray?

If yellow looking the Glycol (a cooling fluid in each tube) is contaminated- usually in these sets the blue is first= no real blue leaves a yellow screen.

Look at the photos and try to tell me which issue you have.

Red, green and blue colors don't match up on screen.

Please replace convergence out ICs (usually two) in TV.
If it is Hitachi 43UWX10B then its convergence out ICs are available in Part Store

Green Haze in middle of TV, Words not sharp

The coolant in the chambers that are part of the CRTs(picture tubes) has been contaminated by foreign matter and the high temps created by the CRTs. The coolant can be replaced but its an expensive and time consuming operation. Some of the parts needed for this repair may also be no longer available. I'd start shopping.

Green dot in middile of my screen

The green dot in the center sounds like a burn mark on one or more of the picture tubes inside the set, and the curved lines are telling me that you have a problem in the convergence circuits. The blue haze around everything white tells me you either have a lot of dust build up on the lens over the CRTs, or your picture tube(s) are very weak. If this set is over about 12 years old, I would replace it. I doubt if you will be able to get the green dot out of the picture without changing the tubes which would be VERY expensive.
