This is a damaged screen. You need to take it to a repair shop and have someone replace the screen, or just put up with it. The screen you're talking about will be expensive, so it's up to you whether it's worth the money.
i fixed my Z3771 by shorting the CMOS/BIOS jumper/s. and it worked. Original Problem: Power supply was ok. But the screen was blank, it wont switch on as well. When a lan cable is inserted into the lan port, the lan port would light and flicker. So the motherboard was getting the power supply. but it wouldnt switch on. So opened the back covers, then the metal plate on the right that covers the RAM, etc. And on the motherboard was the two CMOS/BIOS jumpers. its located on the upper right of the CMOS battery in the image. The power supply was supplying the power to motherboard. i only shorted the one marked with red arrow and the pc beeped. So you just take the jumper out and move it back and place it. then take it out and put it back in the original position, U can leave it for a few seconds before returning to original position. then i pressed the power switch and it beeped and turned on, BIOS was reset. I loaded default BIOS to start the PC. Played up twice during OS loading, but eventually windows came up.
Okay assuming that your bios still comes up.. if so pop in the windows 7 disk and go to bio settings select that your cd drive or dvd drive whatever it is that you use as primary boot so that it detects the windows 7 disc. But if you don't get bio settings then what I would do is take hard drive out and take it to a friends or a different computer and have it as a slave or seconds hard drive then when you load up go to my computer right click that drive and find options for reformat or manually delete everything off that drive.

Question moved to Acer Aspire category.
There a few issues that can cause this, the obvious one is that the battery has failed internally, but it can also be a charging software issue. Try this. Unplug from the mains supply. Remove the battery. Leave the computer for 2 hours. Press and hold the power button for a full 2 minutes. Replace the battery, plug back in, count to 10 and power it back up.
Has the motherboard battery ever been changed? They are critical to the health of the motherboard and the machine in general.
If you have no internal hard drive installed you won't get it to work correctly as the hard drive is where the data is stored for the operating system.
The CD player could be bad or dirty. Blow it out to see if that helps. You might also look in the BIOS to see if legacy support for the CD device is enabled.
Make sure your Acer works with a different monitor. Check Device Manager in the Windows Control panel and maybe update the monitor/graphics card driver.
Go to the bios setup and see if there are any HDD installed. If no remove HDD from laptop then put it back, restart then go bios setup again and see if it is installed. If still not, you might need to replace your HDD with a new one.
- Do a hard reset, remove the battery and AC adapter then press and hold the power button for 20 seconds then see if it will boot up normally. - Next is to test the AC adapter and see if it's supplying enough voltage to power the laptop or better yet try another AC adapter that has the same voltage
If there are lights on the laptop indicating it's on connect an external monitor again and see if you'll get a display.
- Also do try and reseat the RAM, remove them all for couple of seconds then put them back in making sure that they are all seated properly into each slot.
- If all these will not work the problem lies in the motherboard of your laptop.
or take it back to the shop and get them to check it out.

Not to be the person with bad news.
But it is more than likely you have at some point cracked the screen, that is the only way it can get a scratch on the inside.
If you can take to a computer repairer they will confirm if you have and will probably need to replace the screen.
Cost I am not shore but can not see it being cheap.
