HP TouchSmart 310-1125f display is black

Hearing fans and hard drive spin up doesn't necessarily mean system is working - just without video. If you heard a POST beep or the Windows Startup sound that would be different - and good. Is there any video on the screen at all, even just a blinking cursor in upper left of display? If not, your problem is probably hardware such as ram or motherboard. If this system has a VGA or HDMI output to connect to another monitor or TV would be a good check, but AIO system usually don't have that option. Other than that, and this is a shot in the dark: Ensure the system is off, disconnect the power plug, and hold the power button in for 30 sec for a power reset. Then plug in system and try powering it up again. If no go, you may have a hardware problem and will need a PC Tech. Hopefully it is just loose ram.

Need my display to work again

First thing to do is to see if you can see anything on the screen if you use a flashlight right up against it. IF you can then it is the back light that is bad. This could be a failed inverter. If you cannot see anything on the screen connect another monitor to the computer at the video jack. If it works then the problem is with the lcd display and probably is the cable between the monitor and the motherboard.

If you turn on your laptop and no display ever shows, your issue is with either the LCD backlight or the motherboard (since the video card is built-in the motherboard). This will be easy to diagnose.
1.) Plug an external monitor (one which you know works) into the VGA port of your laptop.
2.) Turn on the laptop.
3.) Hold down the FN key (lower-left corner of the keyboard) and press the "CRT/LCD" key (it will be located on the number keys or F1-F12. You do this to tell the laptop that it needs to send the video signal to the external monitor instead of its built-in LCD screen.
If you can see a display on the external monitor, then the issue is with the laptop's LCD screen (about $200 for the part plus labor to install). If you can NOT see a display on the external monitor, then your problem is with the motherboard ($300-$500 for the part plus a lot in labor cost for installation).

Hi What precisely do you mean by VGA display, is your laptop not displaying anything on lcd screen,or its having problem giving display on an external monitor connected via a vga port.
if there is no display on the laptop LCD screen, then turn the laptop on and observe for beeps sounds and hard disk spinning sound if still no display is available plug the laptop to external monitor and again restart the laptop. if there is no display on the external screen and laptop is displaying well in LCD, Then most probably you need to press some keyboard combination on laptop keyboard eg: Fn + f4 , refer to your laptop manual also.

Rello i have a acer aspite 5580 laptop that dont have monitor display but i heard the start up tone. and when i use the vga monitor it display.. what is the problem of my laptop that its monitor dont...

There are some possible options, look close to the lcd screen with a light;
1. If you see something on the screen, but it's very dim, then you will have to replace the CCFL/Inverter of your laptop. The backlight screen would be gone bad, and you will have to replace first the inverter board-a circuit which controls the backlight-. If this doesnt help, then your problem would be related to the inverter cable or the CCFL tube.
2. If you cannot see nothing on screen, then the problem would be related to the LVDS video output. It could happen that the video output inside the laptop don't work property, but external video does work good. This is the worst situation, because you will have to replace the motherboard.

Hey my emachine fan was running and the monitor was not coming on so i off it and spary the board with crc cleaner and now my pc fan comes on but the power signal is off and the monitor is still off

The full motherboard breakdown will be evident if the pc will not come out of the yellow standby light on the screen. The other symptoms here will be the pc may sound as though it is running. This is assuming the power supply has not partially blown. The CPU fan will be seen to be running, the hard drive and cd rom lights will be glowing, and the hard drive can be heard running. The obvious point will be that in these circumstances the pc will show no signs of a display on screen.

What will have happened here is that the motherboard processor socket will have become inoperable. This is a non repairable item, but means the motherboard must be replaced for an effective and full repair.

The cost of this may sound worse that it actually is. The High Street stores will quote you inflated repair figures, when in truth the repair can be carried out by you with my instructions in under and hour and with full effect.
