Perimeter at the bottom of the screen is black

Could be;
Faulty DLP chip caused by static when fitting.
Wrong DLP chip.
Video driver chip issues.
Follow the service manual schematics and with your oscilloscope, find out if the timing is correct.

If your set worked well (no lines, maybe only white or black scattered pixels) before you replaced the DLP chip, then your problem could be that the DLP chip did not get seated properly or the cam screws were not tightened enough after replacing the chip. The DLP chip must be seated properly in its socket or else line and column lines will be seen. There is also the possibility that the DLP chip is defective or suffered static damage while being handled during the installation. Hope this helps.

get it serviced,and stop spamming

Could be bad conections, I gues. I have downloaded the service manual of: http://www.audiolabga.com/pdf/V36-V37-V38_Service_Manual.pdf In manual you can find more information about the problem. Luck! http://www.audiolabga.com/pdf/V36-V37-V38_Service_Manual.pdf

Most likely you have a failing DLP chip. The DLP chip is the one that forms the image that is projected onto the screen. Search for "Mitsubishi Black Dot" in your search engine and you will see you are not alone. Apparently, a lot of DLP chips in Mitsubishi products are failing. With the low price of projectors these days, your best bet is replacing it. If you want to repair it yourself, the chip will run you about $200 to replace and may require soldering.

Hope that helps,

Replace the medieval TV.

i had the same lines on my 65' mitsubishi tv after replacing the DLP chip. after going back over everything i realized that the casinf that holds the chip in was not in the lock position. i took the chip out and replaced it then turned the little locking mechanism to the locked position. now my screen is perfect. hope this helps.

If you get White or black dots all over the screen (DMD symptom)
If you get a pixilated picture (DMD Board)

Hi,If you are experimenting vertical lines ,black bars ,color

distortion,pixilation,or white dots on the screen you might be having an

issue with the Dmd chip.This is how the DMD chip works:

http://electronics.howstuffworks.com/dlp1.htm Basically the dmd chip

is composed of around 2 million pixels that create the image on the

screen.You will need to replace in order to fix your problem.Have a

blessed one!

Hi,

You get white spots inside the samsung DLP tv due to bad Digital Micromiror Device , or bad DMD board .

What is actually the problem is the DMV chip connected to this board . Inside this chip are 3 million tiny mirrors ,and when they physically get stuck , they either show black or white instead of a color
This is well know problem with SAMSUNG DLP...

The DMD chip is failing.If not under warranty expect to pay a few hundred to several hundred to get it fixed

The mirrors on the DLP chip are slowly sticking either fully open (white) or fully closed (black). The part that contains the DLP chip is the Light Engine. It is the most expensive part of the TV.Only the Samsung TVs has this issue.

Replacing the DLP chip and the micro mirror would solve this issue...

Pleaserate this solution,
