1-check your input and output cable.
2-check all your control volume and slider in proper setting.
3-confirm that input sound source is working properly.(try it without the equalizer).
4-if the cables are o.k and sound source is o.k and you still get no output you must pass it to service center.

Acer as3810t no display

OK, best thing to do is test the external video port with a desktop monitor. The laptop will have a Fn key (function) commonly blue in color. The display icon in conjunction with the Fn key will switch between the 2 displays. Common issues with laptop displays is the back light inside the LCD display of the laptop. Power on laptop in a dark room and sometimes you can see the display, just slightly.
If you can see it, replay or have somebody replay the back light in the display. Was This Helpful? Yes OR No *Please vote yes if this helped you

Half of my screen is black

This issue could be 1 of 3 issues or a multiple of each,
1. Damage to the screen itself
2. Damage to the cable that connects the screen to the grapics card
3. Damage to the graphics card

I am not personaly familier with the Aspire One, but Acer usally put VGA or HDMI or both connectors on there laptops if you have one or both of these connections connect your Aspire to an external display, this will check the grapics card, if there are no problems with the external display the good news is your grapics card is fine, however if not there is a good chance it is the grapics card and that requires the motherboard being replaced,

If the external screen is fine, open your laptop (if you do not feel confident doing this get someone who is to check) if the cable that conects the screen to the motherboard is frayed or snapped then that is the problem if not there is a high chance it is the screen but could be un seeable damage to the cable, since cables are cheeper than screens i would suggest replaceing that first as this is usally the issue any way.

Best of luck ;)

Check the monitor input, it must match the video card output Eg. VGA or DVI,
Try a different video cable.
If the video input is correct then try a different monitor to see if the monitor is faulty

Hey i just got a mitsubishi sl25u i have hooked it to my pc second screen cable the computer is running windows 7 and has poped up as my second screen it know what it is but i get no signal displayed on my...

A couple things to try. First connect a second monitor to the output of the computer to make sure that you have a valid signal coming out of the screen 2 output. If you do then connect the projector and make sure that you have selected the computer input usually VGA1 or VGA2 as your input signal. If the monitor doesn't work then you need to hit the function key on the top of the keyboard to turn on the second screen output.

Well i installed my grapics card.. it was running fine for a few days .. Then i started getting the analog power savings mode over and over.. pls helo

An outdated computer system would malfuntion after installing a new graphic card because is incompartible. As matter of fact, a new graphic card would card picture blank out with older model capacity computers. It is not possible to increase grapics to certain computer systems. Dos operating systems would hardly display any pixles than digits. Check on the computer compartibility operating systems, maximum graphics capacities before introducing the most updated version packs on the retails.
