Chosen Solution
I’ve had this plasma TV for about a week (second hand). What I’ve noticed is that when the TV is displaying a lot of white, the whole display quickly but gradually dims. When displaying other solid colors (red, blue, green), the image is truly vibrant, so it is not the pixels themselves, apparently. This makes me wonder: could it be possible that the TV cannot draw enough power to power all colors at once to display a lot of white properly? If so, is there any way I could tune the TV so that it can draw more power when needed? As a note: NONE of the TVs settings do the least to remedy this issue. It is also a gradual process: The more white that is displayed, the more the whole screen dims. This is particularly evident when connected as a PC monitor and I drag to enlarge, say, the task manager.
It sounds like it may be due to the settings on the television. It says you have a Pioneer PDP-436PE You can find the manual for your television here: https://www.manualslib.com/manual/130290… You can view it online or download it.
