Can this be fixed ? what is the problem?


What your describing sounds very much like a video board issue some part is not working properly until it warms up. Eventually it will most likely need to be replaced, If you are not sure what board or part is bad, in the long run it might be a better idea to just replace the TV.

Samsung HL-R5688W DLP TV Screen Burn


I don't know where you got the information that burning could not happen but that is completely wrong. If it is a monitor, tube tv, LCD/LED, DLP or any other kind of viewing device it can burn. With that out of the way if the lamp warning is coming on then it is time to replace it but your image problems are deeper than that. The screen appears to be separating. By that I mean there are three layers and sometimes more depending on the manufacturer that display color. Think of it like saran wrap laired on top of each other. As they get old or of poor quality they start to separate and show some pretty funky imaging. Without the TV in my shop I most certainly cannot 100 percent say for sure that this is it but I would strongly consider this as not fixable.

InFocus LP600 - A vertical shadow on the Left-side covering about 20% of screen.


The light tunnel inside the "engine" is either out of alignment or the glue holding the tunnel together is coming unglued and 1 of the 4 sides has fallen in. There are 2 screws to adjust this if the tunnel is still intact. One or both screws can be accessed by opening the lamp door and then you have to remove a thin sticky cover. You will see 2 small screws that will have to be adjusted with a small torx (3) or allen. You will have to have the safety switch pushed in with something and adjust while the projector is on, using the most easily accessible screw, turn it towards the direction of the "banding". It should decrease. If not, turn the screw the other way. The screw that is not so easy to get to is for adjusting the banding the can appear across the top or bottom of the screen. If the banding gets worse or even starts to show diagonally across the screen, it is a good bet that the tunnel has collasped.

Colors on the left side of the screen are shadowed with duplicate


Your set has a convergence problem which is a common issue.


Take a look at this solution posted earlier on Fixya. It worked for me.

Shadows on screen


Try moving a medium powered magnet (not one for picking up heavy objects and not a refrigerator holding one) over the distorted area. If that doesn't work, try a more powerful one. This worked for my Toshiba LCD. Good luck!

Mitsubishi WD-62827 Problem


Uh Oh! Unless this is something simple like a loose piece inside the projection chamber shadowing the screen it would have to be the light engine ($$$) warping due to overheating of its plastic housing. Check inside the cabinet for loose objects in front of the lens, then clean all the fan filters, then call your warranty company.
Hope Ya Fix It!

Left side of television just started having a shadowing problem?


I have the same problem and was told by a technician that I need to replace the light engine. Probably around $ 700.00.

1/2 the screen is viewable


You would be wrong. Lamps do not do that. They either work or they don't, they do not cast shadows or give half an image.

What is going on is the light tunnel has failed. It is a small, 4-sided mirrored tunnel that focuses the light into the optical chamber. It is directly behind the color wheel. I've seen this probelm dozens of times.
