Acer Aspire laptop backlight stopped working?

GTO656 · 29 Sep 2011 at 14:15

Hey guys,
Well a few days ago my backlight stopped working as I was using it, The screen was dark but if I shine light at it the screen is visble. It was hooked to an external monitor and everything is working fine.

The screen had some red on the laptop screen previously everytime I boote it up and became whiter.

I have read that it is either the inverter need replacig or the backlight bulb or more worse the monitor. How I identify which one need replacing?

cheers

Yes its the cheapest fix and most likely cause of backlight failure, then its either the screen or the cable and lastly the motherboard.

Might take a few weeks, although I just realised the mouse pad on it stopped working aswell, keyboard is fine though.

Is it an Acer 5920? Sounds like a faulty cable.

Nope its an Acer 5612WLMi laptop, Im waiting for the inverter now so I will update this when I get it.

knackered microswitch that turns the backlight on when you open the lid? or the contact for it?

they go quite often on the laptops i repair at work, if it's not those it's normal the screen itself. no idea on Acer's though.

Im not too sure if my one has a microswitch where do you find it? I hope its the inverter though since I just bought it. The mousepad on it stopped functioning so could that indicate any problems?

The backlight decided to work again its been 30minutes

it's on the motherboard (well the usb daughterboard on the ones i repair) next the one of the hinges. you can see it after removing the panel above the keyboard.

if it's working when you push it the backlight will turn on and off.

It might be worth searching for a tech / service manual on how to open just the bits you need rather than taking everything apart. Has worked for me for HP and Dell thus far

GTO656 · 19 Oct 2011 at 10:13

Lol I already opened but found out the left side of the new has 6-pins and the connector in my laptop has 7-pins

dammit got 2 send it back. I'll try and look into the backlight switch.

GTO656 · 20 Oct 2011 at 00:47

PS does any 6pins to 7pin converter exist lol??

GTO656 · 20 Oct 2011 at 00:50

Does any1 still know why the mouse pad malfuctioned right after when the backlight stopped working. surely something trigger it
