Shadow down right side of screen on a toshiba 44NHM84 44" DLP television
I have seen this problem on the internet but never a solution. I have a 5" wide shadow down right side of screen on a Toshiba 44NHM84 44" DLP television. The set is barely a year old. It happened overnight one day and has been like this for about 2 months. You can still see the picture through the shadow. Any ideas?

Shadows at the bottom of the screen sound like moisture that was "wicked up" between the screen layers and dryed out leaving a stain. DO NOT get these screens wet, use nothing but a damp soft cloth; just a few drops of water running down the screen can cause a fairly large stain. Some people have suggested that they may be professionally cleaned, but the risk of damage is too great on the user level.

You need to replace the light tunnel.you will need to remove the lamp and color wheel along with the lamp housing and fan housing to replace it .If you are not comfortable taking things apart you might want a tech.
Is it an LCD or DLP? The Model below suggests it is an DLP. Sounds as if you have the dreaded light tunnel collapse common to all LG DLP TV's. Inside the light engine there is a square tube made up of four mirrors. These mirrors deform and crack with the heat of the lamp. They fall down over the light aperture and cause a shadow of varying degrees. It is fixable now at a realistic price ( used to have to replace engine) as LG have made the parts available. It would take a competent tech around three hours to complete or if you are technically minded you could do it yourself. I hope this helps. Good Luck.
