Hello
Its video processing section has damaged. It is fixable. The section can be replaced as card basis. No repair to it is possible, as the components in it are fixed with CNC machine. OK.

Hello
Your TV is in warranty period I thinks. If so, company is liable and will repair it free fo charge. There is "repair,replace, refund gurantees. Your gurantee card and broshure will tell you that. Look at it.
For what you are going to take the risk.

I had the same issue on this board where it came with a Samsung 512 MB 533 MHz PC2-4200 DDR2 DIMM. I put in a 1 GB Kingston with the same specs (533 MHz PC2-4200 DDR2) and it would not recongize the Samsung anymore with the system reading as 1 GB of RAM instead of 1.5 GB. Tried every configuration and would only see the Kingston. It would only see the Samsung if I pulled out the Kingston regarless of the slots I use. So, I just bought the exact same make/model of Kingston and it recognized that fine and the system now has 2 GB of memory (max this board allows). And, I had already installed the latest BIOS for this board from Intel before doing all this so wasn't an old BIOS. I'm figuring the board didn't like something about the Samsung memory (speed, module configuration, etc.) that made it not play nice with the Kingston. If interested I bought the DM8400A/1G Kingston modules. And, this board appears not to support dual channel memory. Only has channel A, slots 0 and 1, and I read need two channels to support dual channel (seems obvious). Boards that supports dual channel memory normally have 4 memory slots, two for channel A and two for channel B, then put in matching modules in slot 0 for channel A and B and have dual channel memory access. And if want more ram, then matching modules in slot 1 for channel A and B.

You need to take out the DMD bord and open it up then remove the DLP Chip very carefully and blow out under the chip and all the components in the box with dry air something with a dryer on it then reassemble the chip on to the bord and make sure that the three screws that holds the mount that houses the chip are snug then you will need to put the Bord back in and have someone Else watch the pitcher so you can center the pitcher. This happened to me with my samsung tv and ran across this in sum service notes for this problem. Hope this helps

It is called a DMD bord and you can fix it your self look at my ether post on how to clean and tighten the screws on it this should fix it
