The splotches are magenta, not red, which suggests a green channel issue. That said, this is not a common problem for which there is a solution discussed. It looks like the green channel data is slightly corrupted, but this could be caused by any of: main board, DMD board, or LED driver board. Or possibly even a power supply issue where the green LED current draw causes the power to fold back.

Is there a history of prior or related symptoms for your set? Is it constant, or does it come and go?
