It has blue spots (pixels) around the edges. There is a egg shaped center that does not have it, all other places do. It stays on the entire time, even after turning off the TV, until the lamp goes off....


Hello
This is really a problem to some Mitsubishi projection TVs.

This LCD Projection Television uses three LCD panels to create the screen image. This technology creates the image using small dots, or picture

elements (pixels). Your LCD Projection TV is manufactured to a high level of performance and quality, in fact, 99.99% perfect in the number of

properly functioning pixels. As in other display technology, sometimes a pixel is continuously active, inactive or the incorrect color. Our standard is
clear; MDEA warrants only that the percentage of properly functioning pixels will be not less than 99.99% of all pixels.
This is the company says about this problem. Your set need service care fro authorised service center.

BEFORE REQUESTING SERVICE, please review the instruction booklet to insure proper installation and correct customer control
adjustment. If the problem persists please arrange for warranty service

Green tree like on screen


If this is a 3 LCD this is called the scribble when pixels are stuck close together. The optical block must be repaired. check this site

Screen has green tint, it is an LCD 42 inch


First of all, that is not an LCD tv. It is DLP, which is a common mistake because the picture is very similar. DLP tv's use a high-power lamp that reflects light off of thousands of tiny mirrors into a spinning color wheel which gives the reflections color. Each little mirror is one pixel, which can be any color depending on the hole that it goes through on the color wheel. The color wheel may be spinning slower than normal, which could make all of the light go through the green filter on the color wheel, and give your screen a green tint. Have a trusted mechanic take your tv apart and dust the inside. If that doesn't fix it, you may need a new color wheel or bearings for it (that help it spin). You should not pay more than $200 for a bearing replacement on this tv.

Thanks for asking.

TV issue


There are many causes for spots on top of an LCD rear projection tv, you are probably in the first two cases, both require part replacements and repair job.

If the spots are faint blue, green or pink shadows, then it can be a problem with the anti polarization panel placed on top of the LCD.

Similar spots (colored shadows) may be caused by a problem with the light engine, in that case the fix will be expensive.

If the spots are bright lights, like an aura, that is a problem with the color wheel.

Problems on the light tunnel can cause static gray shadows.

If the spots are static dark stains than that is lcd liquid, the LCD panel must be replaced.

Green and Blue spots on screen


Sounds like stuck pixels, you really can't fix that. Do some google research if you are curious what a stuck pixel is.
