Just an update, as most of you may remember I only tweaked the Set_up to lower my MLL and I do get massive misfires on my PX950 on start up when the room was cold and then it would completely clear up after about a minute or so, keep in mind that during that minute blacks were at or close to zero black but too noisy for practical viewing.
Well the temperature is starting to rise with the spring but oddly enough I’m now experiencing random (but not excessive) red pixel misfires even after warm up, this may be from the fact that there is less of a temperature difference after start up and the temperature sensors are keeping the overall panel MLL at a lower level as blacks have gotten blacker but bordering on the level closer as to when turning on the set in a cold room.
Another scenario may be that the power supply voltages have shifted slightly but my intuition says it’s probably the former.
At this point the misfires are not obvious from the viewing position and appear not to be stationary, being more like random stuck pixels which disappear as the screen is refreshed so I may wait until we approach the lazy days of summer and see if the MLL continues to drop but unfortunately most likely with even more misfires but I'll have to wait and see.
At which point if they do I may need to get out the screwdrivers again and try tweaking the Set-up a bit counter-clockwise and maybe try the Set-dn, I’d rather leave the power supply voltages at the factory settings to adjust the MLL, (not a lot mind you, more like the ST/GT30s and not VT30 blacks
), just enough to keep the misfires to a minimum.
Either way I’ll keep you all up to date.
