Hello, I own Acer Aspire 5349 laptop (Core-i7, intel HD graphics 3000, 12GB RAM) and I have got a problem. Not long time ago my screen started acting weird. When I was on baterry screen backlight started to blink but after some time it stopped and everything was OK. But now it is here again but worse. Backlight turns on on baterry only for few seconds then it start to blink and then it goes black (I can see the screen with torch and I am able to connect it to external monitor where is everything fine). I thought that somewhere in the wires is bad contact but I tried to move with them and it had no effect. I searched on google and found that maybe digitizer is dead but in this case backlight won´t turn on at all. Screen on laptop works fine only if it is connected to charger. If I disconnect, screen turns black. So, do you have any ideas how to fix this problem? New screen is kinda expensive and I don´t know if there is really problem in the screen or on the mainboard. Thanks for help. - Gamemaster
