I have an Acer Aspire 4220,when i switch it on it turns on but the screen is black. I connected it to a monitor through VGA cable and it works on the external monitor but not in the laptop screen. I have already check the RAM and even disassembled it but it still doesn't work. so I connected it to external monitor and check the BIOS press F9 for load setup default and it works, the screen is already working. But my problem is when I turned it on again, the screen will again appears nothing so I have to check the bios again and it works again and appears nothing when I turn it on. Just repeating the process..

what will be the best solution to this problem?
thanks

Try to boot up the ACER and then press fn+ F4 and if that doesn't work go into your settings for screens and resolutions and so on when connected toe external monitor and there change setting on wich the screen is showed :)
