LG RU-44SZ51D Ragged Black Stripe down Left Side of Screen and Grainy Picture

My tv just started looking grainy and "unsharp" and has a strange shadow "stripe" only on the left side of the screen. it is not uniform like a bar, it is more like a long thin triangle thick at bottom and comed to a point near the top of the screen. It is black, but translucent since I can see the image through it. It is even there when I turn the tv off while the bulb cools, but when the light goes out you cannot see it on the screen. Help...

I came looking for a solution to the same prob but on the right side of the screen, i did take out the lamp which is on the right (looking at it) you need to undo two screws on the case and two on the unit and just pull it out, and i found quite a bit of ash there,almost like ciggy ash, i cleaned it out but problem is still there, so if i find a solution i will repost and would like to hear from you if you find one many thanks adders

push the MUTE button on your remote control at the same time as pushing the OKbutton on your tv set . Hold for at least 10 - 15 seconds . You should now see a page on your screen that will tell u total lamp hours

Fading screen

If you're seeing a shadow either vertically or at an angle the most common/probable cause is the light tunnel in the light engine. I have this same problem with my ru-44sz51d and have found many people with similar problems. For reference search "dlp light tunnel" as many samsung dlp's are suffering from the same problem and have been since they were purchased. You should be able to repair this yourself, but only if you feel comfortable and are knowledgable in such a situation. The repair may consist of replacing any number of the 4 or so mirrors or just reapplying the silicone adhesive to the original mirror. As I have not done this yet myself I can only speculate and refer to topics I've read about. Good luck

Shadow down left hand side of screen

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.
