When you power up the screen, keep the power and auto buttons both pressed. That seems to reset the screen. After that when you open the menu, a small F appears on the left side of the contrast icon. Go to that red F with the arrows and press menu. Another menu will popup. Choose 'Burnin' and set it to off. That's all !
When there is no longer a signal to the monitor, it begins to cycle through the primary colors. Not a big issue, however the power switch does not work at this point and he only way to stop anything from being displayed is to unplug it. Otherwise the monitor works perfectly. Even the power switch.
