HLR4266W I have a dark shaded area down the left side of my screen

The water entered the TV and now it is showing different shades. You can see clearly the other half and the other half has a whitish in front and You can see through it though. Please help

TV ON, IT HAS A LOT OF WHITE DOT ON SCREEN

No the probelm is the rubber guard on the light tunnel is loose,i just fixed many of these, probelms if its not the dust its that rubber guard. All you got to due is take the color wheel out and look with a mirror see if it square thru it, Hope that helps.

Tv shuts down,restart with control box, Timer light comes on.
May happen 2-4 times
Boney,

I can see through the shading. This problem just came up a couple of weeks ago. I have tried adjusting the B screw on the light tunnel, very little movement there and it did not seem to make a difference, i was not sure how hard i could turn the B screw, i only turned it softly as far as i could left and right. I have had my set 2 years+ so i am out of warranty. light engine from local service repair are $700.00+ and are on back order with no known ship date, and at that price it is not worth the trouble. light tunnel was $150.

The main cause of shadows on DLPs, that I have found is due to a light tunnel mirror collapse. It's a difficult job and the light engine needs to be torn apart.
You can replace the entire light engine, not a hard job and the price would be the same as if a technician had replaced just the light tunnel.
If you would choose a technician call:
1-800-SAMSUNG for a recommendation of a servicer in your area.

How dark? can you see anything throught the shading.. still might be a cap in the video out circuit but the one Im thinking of shades the right side and brightens the left.

sometimes RF or HV arching causes shading on left, mute your sound and listen for sizzle noise in the back.
