I have a 7" Lilli (older model) that I have directly wired to my Opus w/Coyote's auto-power on mod -- works great.
However, I noticed that the LCD is not as bright as it used to be ... atleast I dont think it is. So I go to the menu and adjust the brightness and contract to their max .. but when I hit the exit on the On Screen Menu, the Lilliput starts cycling through colors with the message "BURN IN..." on the screen and it never stops. No amount of button pushing will stop this and I have to shut the car off so that the computer powers down (and hence the screen powers down). WTF is going on?
Also, since the screen is powered by the Opus, will it retain it's brightness settings or loss them everytime I power down?
I found this old thread whilst researching a problem I have on my K301 In Dash with "screen burn" or more technically image retention I've recently discovered after a long drive 4 hours.
I suspect that what is being described is a built in method for testing the monitor and/or removing a retained image by "exercising" the pixels. I think you've just found how to activate it (set everything to max).
"Retained images can be removed by "exercising" the LCD pixels to bleed-off the residual electrical charge in the affected pixels. This can most easily be accomplished by using a random pattern screen saver that changes the screen image repeatedly. The time required to clear the stuck image can vary widely (minutes, hours, days) depending on the panel technology and the severity of the image retention." Source Dell
