Description of crawling Moss:
Crawling moss" is seen in dark areas of a movie or TV show.This is a picture artifact known as dynamic false contouring, and it is usually seen on older plasma, DLP rear-projection and some LCD TVs.
i would say over or around, there is picture and it is watchable but not the quality HD picture that this TV delivered up until a month or two ago.
I believe the menu is affected.
The crawling moss does affect any device input to the TV (Cable, Xbox360, Wii, DVD-receiver).
Technical ability is between a 1 and 2:
I opened the TV and replaced the fans (both), Color Wheel, lamp ballast. I am very comfortable inside a PC (in fact my background and education is in Computer Hardware/ Computer Science) but i have not soldered in a long time and would give it a try on a cheap inexpensive part or device that is unrepairable otherwise but when it becomes something worth considerable value and is still serviceable rather not. I do have a volt meter and could check voltages if required. I am also a big Home theater enthusiast and am only limited by the money i have to spend and the thin floors that separate me and my downstairs neighbor.

Background on problem:
TV started making noise (clunking sound).
I ordered and installed/replaced both fans.
Still making noise. Did research...color Wheel possible cause
ordered and installed/replaced color wheel (made sure to vacuum all the broken glass)
No more noise.
New problem (not seen before)...Crawling moss. I cant remember if it happened shortly after replacing the color wheel or it was there since replacing the color wheel. either way it wasn't long before we had moss.
Talked to samsung support and after getting through their script he mentioned the DMD board or chip needs service/replacement.
Knowing it could be lamp related and the lamp ballast was cheap ($100) and easy to replace i ordered this first to eliminate it.
Still have moss and i think it is getting worse.
So doing some research in buying replacing the DMD board/chip and before i committed to the $400 -$1000 this part might be i stumbled upon your site.
So i am looking to define what is causing the moss.
whether it is an adjustment of a working part or setting or do i need to replace a part and which part and where to buy it at a good price from a reputable seller. If it is teh DMD board chip i would like to know do i buy the chip, the board, or both together and the differences.
Thank you for your time,
