I am talking to someone about buying a Max Impact board set with 4mb TRAM. They say that after 16 hours of testing, not sure what load or stress test they are using or if it's just left on with no specific load, that a dotted pattern appears on the display. They are offering the board set a discounted price, more offering it as a TRAM sale with free Max Impact boards as is included as a bonus item. 

Has anyone had this on a Impact system? Is there any hope that disassembling the board set and reassembling might solve a connection issue between the boards? Is there any hope there's a reasonable fix for this? Or should I assume one of both of the Max Impact boards is faulty with no practical hope for repair? Is it possible the artifacts could be a problem with the TRAM board? Or would flaws in the TRAM only show up in texture mapped 3D imagery, not on the overall display?
