Acer Aspire 5732Z. I have replaced both the screen and inverter board. I’ve also updated the BIOS. When I hit fn + F6 the screen is very bright and vivid for the duration of time I’m hitting the button repeatedly. If I try fn + the right arrow button to brighten the screen nothing happens. I’ve hooked up the laptop to another monitor and changed display settings and still nothing. Any thought?
i had similar issue, it turned out that my screen had a light sensor that dimmed the screen wheter i wanted to or not
i was unable to adjust it with settings or anything
so i went to device manager, found the sensor and simply turned it off
now everything works fine.
