I have had some issues with my LCD screen & had it replaced about 1 year ago (it went psycodelic). Now the screen is really faded out. I will be sending it back to Acer (thank goodness we bought the extended warranty), but I was wondering if there is a way for me to set the "contrast/brightness"? I am not REAL computer savy, but I can muddle through step by step instructions.

Re: Faded out Acer LCD screen
It's not a contrast / brightness issue, even at the lowest setting the screen would look normal and probably not the way you're seeing it now. It's likely that the inverter or backlight went out on the lcd. You could possibly turn them up the highest level, but it would still need to be serviced by Acer for it to work correctly.

That sounds like the bulb in the screen is blown. I have changed them at times but it is very tricky and I'm pretty sure you won't find a reputable place to do it for you. Effectively in answer to your question the only rational solution is to change the LCD panel, it's not very difficult to do on the aspires, just a few screws and peel off the tape holding the screen connector in place, disconnect the inverter cables, (pink and white) and swop for the new panel. check ebay etc for a new LCD panel they're not that expensive. Try to get a new one instead of a second hand one. to find out what panel you need, you'll have to open the screen and look at the back, it'll have a paper sticker showing the model number.
So, if you can hear startup sound then motherboard, RAM and HDD is OK! Try to connect it with external monitor, if it's working on it, then problem in LCD, LCD light or LCD cable. If not working with external monitor then it is video card problem, if card is integrated then you need to reball or change at all south bridge on the motherboard, if video is as module card then just replace it with compatible one. If LCD cable - disassemble laptop to get LCD cable and test each wire with any multimetr with sound beep and replace it if needed. If LCD light - try to take LCD screen under good lamp then power on laptop and carefully look to dark screen if you see very dark Windows boot screen then you need to disassemble LCD housing, disassemble LCD, remove and replace LCD lamp with working one. If all this cant help, then you need to replace LCD at all.
If you can connect your VGA output to a regular desktop monitor and it works during the startup process, then it is probably you LCD screen. There is no way to know for sure that it is the backlight unless you replace it.
The lcd is going to need to be replaced, its a problem inside of the lcd with the cells cause they went bad.

Cheack your video with and external monitor, if you have video then you will need replace your inverter or backlight or both, if your lcd it is nor cracked this is a common problem with the lcd.
You need to remove your frontal plastic in order to see your inverter, if this didnt work replace your backlight.
