Having problems with your Acer Extensa 5420-5687 Notebook ?

Right now, my laptop screen is black. I can hit Fn

\015 Right now, our Acer Entensa 5420 laptop screen is black. I can hit Fn and F6, and it will come on briefly. When it does come on, it has a pinkish hue behind it. After it has been shut down for a while, it will stay lit up with that pinkish hue long enough to check some email, about 5 or 10 minutes, but then it goes black again. Also, when it I hit the F6, I hear a quiet sound, maybe like a hissing sound. Is this the lcd bulb, power inverter, BIOS, or what? Thanks!\015

Answers :

I'd guess that it's the CCFL (backlight bulb) going bad. What points me in this direction is that you mention that the backlight (when you're able to get it to turn on) isn't producing bright white light (and pink is one of the colors that normal fluorescent tubes produce when they're failing). You're in luck because CCFL backlighting isn't the most difficult thing in the world to replace (if you can handle delicate electronics) and you may just be able to hack together some LED backlighting for yourself while you're at it. There are a few reasons that LED backlighting is better than CCFL but the most important is that LEDs last pretty much forever.

There are a number of video tutorials on YouTube about replacing the backlight of an LCD display and a few of them detail the installation of bright-white LEDs in place of CCFL backlights. If soldering and math aren't your strong suits a drop-in replacement for the CCFL tubes should be fairly easy to find online...
