Acer Aspire V3-731 Screen showing lines at bootup

by Aug 8, 2014 1:47AM PDT

Hi everyone. Forum Newbie here. Would really appreciate some advice here please....

I have an Acer Aspire V3-731, that when booting up, shows a black screen for the top 3/4,

and lighter grey for the balance of the screen. After a few seconds it changes to

vertical lines and no further changes.

I have tested the connection to an external screen via the VGA port and this worked

successfully.

I have removed both 4GB RAM, started with them one at a time, in different slots as well.

I have opened it, checked that the screen cable (on both sides : motherboard and behind

the screen assembly) is correctly inserted and not damaged.

At the time of its failure, the laptop booted as normal and then changed to the black

screen, without any changes for the better since then.

Aspire V3-731
Intel B970 2.3GHz cpu
Intel HD graphics
17.3" LEC LCD screen
8GB DDR3
1TB HDD
Windows 7 Home

If the external vga works.

The the motherboard, LCD and parts in between are suspect. It does not tell you which it is but you can guess which it may not be. I'm not there to watch the LCD to rule that out but let's say you can't tell which part it is. Use the Old Tech's sage words here -> "Replace the cheapest part first."

Hardware must be replaced then

Thanks R Profitt for that reply. So basically you're saying there's nothing else I can do, apart from replacing either the board, LCD, etc ?

Sorry but

I can't guess which part failed. But I can share the old tech's sage advice. Your reply sounds as if you hoped it was not any hardware issue but since it does it when the BIOS starts, that's a clear sign there is some hardware failure.
