Possible there is an error in the power supply, or in the display. If you can connect an external display and see if there si good display then it is confirmed.
Please try this and confirm

Sometimes when i used my laptop (acer aspire 4520) suddenly hank and then the screen turn on black like shut down.. can you give me solution for my problems..?


sounds like an issue with the FSB controller chip or the graphic card. There are similar problems with some HP laptop models so you may want to take a look at this repair manual for HP laptop with random freezeups. Basically what happens is that this FSB controller chip loses contact on several pins and you'll need to force it down or reflow it. The other option is to look for a replacement motherboard but this is a much more expensive solution.

Hello there:
These screens have a very fine neon tube that runs thought the screen
and over time these will blow out expecially if the lid is slammed down or the laptop has been dropped there is also a inverter that runs the tube that sits on the motherboard that can go out too But not too much
SO what you are going to have the screen or the inverter serviced and have the necesary parts replaced by a qualified technician ok?
I hope this has been very helpful for you>
