50HM66 screen problem
The right side (one-half) of my Toshiba 50HM66 screen is dimmed and the left side (the other half) is normal. Is this the light engine problem or something else? I thought it was a lamp problem, so I purchased a new one, but didn't help.
Re: 50HM66 screen problem
Hi, Usually when this happens is related to a bad DLP chip, which is part of the DMD Board (Digital Micromirror Device) and light engine.
Watch this video that will explain you how your TV works:

After watching the video you will comprehend that half of the DLP Chip is failing, you have a image since probably 1 column of mirrors is working and 1 isn't, 1 working, 1 not, 1 working, 1 not. And it creates the effect of dark image.
Our sponsor's have the light engine:http://www.discount-merchant.com/TOSHIB ... 180248.htm
The DMD board is the one on the bottom inside the metallic enclosure, the dlp is under the big heat sink.
There is people selling bare DLP chip's, but it will be hard to find one for a Toshiba TV.
Change is the only constant, we must become the change we want to see.
