Dark bottom half of screen and dark patch in corner

    There is a shadowing on the left hand size of the screen that is slowly getting larger. It's shaped like a tall triangle, larger at the bottom of the screen. I have heard that there are several mirrors in the light engine that can get out of alignment due to thermal stresses. Is it possible for this to be fixed by the consumer, or does it need a professional?



    I'm just accepting it as the shadow is still small enough to not be too much of a issue in watching the TV.

Thanks for the picture - that's a big help.
It looks you have the dreaded light tunnel collapse common to all LGdark bottom half of screen and dark patch in corne - 1.gif 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.
Hope Ya Fix It!

My Vizio TV has dark spot top left corner


Hi Brandon,
I am afraid that the dark spot in the screen is not repairable. Manage as long as you can or go for a new tv.

IH252 inc monitor bottom half darker than top.


Thin screen LCD monitor brightness controls operate several fluorescent lamps called "backlights" that are positioned behind the LCD display. Typically, they're located around the edges of the screen - sometimes just at the top and bottom, and other times at the left and right edges and others still at all 4 edges.

Fluorescent "backlight" lamp, inverter & connection wiring.

The lamps are miniature versions of those sold in stores. They require a support circuitry called an inverter that convert & boosts the level of DC to AC voltage performing the functions of a ballast in a traditional fluorescent fixture.

The reason a part of your screen remains dark is because one or more of the components in the picture above has failed and will not allow the lamp to shine. Replacement lamps and inverters aren't expensive - but requires patience and the ability to disassemble / assemble the monitor (which is usually harder to do than it appears) and solder. They are available various lengths and color temperatures (you must get a lamp that is identical or it will be noticed). If this is a new monitor - you ought to return it for replacement. If used, consider the cost of purchasing a replacement (new or used) vs. repair.

I hope this helps & good luck!

Dark Screen


It sounds like a back-light problem. Check all the CCFL back-lights.
