Having problems with your Samsung 931BF 17" LCD Monitor ?

Samsung 940NW Streaking

\015 I have the Samsung Syncmaster940NW flat panel LCD monitor working with an eVGA 9800GTX+ in Windows Vista Ultimate x64. I got he same strealing effect a couple of months after buying the monitor. I also tried using a can of compressed air to blow inside the monitor vents which seemd to eliminate the problem for a while, but it came back over and over. I got fedup the other day and dismantled the LCD and used the compressed air to blow out the circuit boards on the back of the panel directly and also used a bristled "hog hair" art paintbrush to clean the two boards. I re-assembled the monitor and the streaking had definitely reduced significantly... but some remnants were still there. This leads me to believe that either:1) It is something to do with the coldcathode tube assembly behind the LCD which has something to do with dust contamination.2) Some form of overheating somewhereI more think it is number one. I am afraid to dismantle the actual LCD screen assembly because I don't know what to expect behind it. If anyone has an old monitor that is no longer of use and they can disassemble it and let me know what's behind (or can send me pictures), I would be willing to take a shot at it and see if using the compressed air behind it would work. I think I'll aslo ask Samsung.\015
