A while ago, my Aspire 5552 stopped showing picture. When power button pressed, it would turn on, and even boot to operating system (the OS welcome sound was played and also welcome sound of some programs), but the screen remain black. The back light was working normally (when splash screen should show up, the screen became brighter). After some search on internet i found instructions how to update BIOS when screen doesn't work and it solved the issue, after that it worked normally. For a while.
Today, i was working on it and suddenly, the screen turned black. After a restart it remain black. Like the first time, it boots to OS, turns off when power button pressed, the backlight is working, but there's no picture, it stays black. I tried the same procedure to flash the BIOS like the first time, however, this time the flashing process doesn't start. I tried second monitor, no luck. I downloaded the latest awailable version of BIOS, which is 2.14 released on August 8th 2011. Should i change the name of FD file? (i tried with the original name and with ZG5IA32.FD (first time this name worked)). Or is there some other Bios version i should try? Did maybe the procedure change when it was updated last time? Should i press some other keys to start flashing instead of FN+ESC before pressing the power button?
I'd appreciate any suggestion, but also hoping to hear from Acer tech support, as when i tried to conntact you through the Acer site for my country, it keeps me going in circle (choose country -> contact acer support -> choose country -> support....) and when i tired to contact through Acer US site, neither serial number, nor SNID are accepted, so i can't contact you.
