Projection Screen Tip #3


In front-projection applications, control of ambient light near the projection screen surface will enhance the contrast and brightness of an image being projected. In order to achieve this, place the screen in an area where ambient lighting is low or controllable.

Tip

Rear projection TV displays a shadow on one corner or side of the screen.


Hi.

This tip may be helpful only if your rear projection TV is displaying a darker shadow on one portion of the screen. If the shadow shape and size will not vary, that means that there is probably a detached mirror in the device called Light Tunnel, located inside your TV.


Most rear projection TV works projecting the light from the internal lamp on the screen. Before reaching the screen , the light will pass through a 'pipe' whose internal surface is covered in rectangular mirrors, located all over the tunnel surface.

A quite common fault is caused by one of the mirror detaching from the the light tunnel internal surface , and falling down or hanging in there. This will be seen on the display as a darker shade located near to one side of the screen.

The light tunnel is located in the light engine. To repair the problem the TV must be disassembled by a technician. Accessing and disassembling the light engine is not a repair that can be done by the owner.

Click here to view pictures of a light engine for a Samsung rear projection model. The tunnel is the optical device located in the light engine.


If you are a technician, to replace the light tunnel you will have to take apart the light engine, that apart of being quite a sensitive optical device, is also the most expensive part on a rear projection TV.

In that case you may find useful the service bulletin posted below, that is illustrating how to replace the light tunnel on a light engine for Samsung rear projection TV. Please be aware, that if you attempt doing this operation without sufficient knowledge and experience, you may damage your TV set beyond repair, as the light engine is very expensive.
