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?

Thanks for the response cosmicvoid - only issue with set was "white dots" & DMD chip was changed in mid-2014 after a bit over 5 years & new DMD chip has worked fine. The current issue did come & go for 3-4 days but now appears to be permanent. It appears over all 3 HDMI inputs, I have not checked component inputs or any others; only HDMI. Sadly, the only folks "fixing" these was ruined by the flooding in August here in South Louisiana. Trying to determine whether unit is worth a fix or time to get 4K set? Thanks again for any further response!
