Question about Office Equipment & Supplies

2 Answers

I have an Hp Pavilion a1120n (media center PC). when I turn on the computer the monitor turns on and says VGA input: No signal and then it says monitor is going to sleep. The computer is turned on booted up to the best of my knowledge based on the sounds it makes. I can use press the number lock and the caps lock and the lights on the keyboard will turn on and off to indicate when the caps lock or the number lock is on or not. The monitor status reads: VGA input: active Mode: 1280x1024-60Hz then it says Auto adjustment in progress and then the screen goes blank I took it in to a Computer repair store and the guy said that he could see nothing wrong with the computer and to the best of my knowledge was able to get access to my screen picture and files on his monitor. However when I brought the computer home and connected it to my own monitor (HH vs17) which came with the desktop I got the same monitor status response has indicated above. I thought maybe the monitor was broken so I hocked it up to another Hp monitor (HP w1707) and I got the same results with this monitor as i had with my own monitor. I have asked friends who are self-proclaimed computer experts and they have no idea what to make of it. SO please if anyone knows what the issue and how to fix it if that's posible please let me know,

    I have Windows XP student teacher edition preferred.


    As to your advice to go to the device manager (the easiest way is to click start and type devmgmt.msc and hit enter) I can't even get windows to show up on my screen. Nothing shows up. sometimes my Monitor status is: VGA input : no signal and after that the screen says: monitor is going to sleep. When it the monitor status is: VGA input: active mode it to auto adjust and when that fails the screen stays black and nothing shows up. I have not be to even get the windows logo to show up let-allown get to the start menu. So don't think i can check the device manager. :(

This is issue with your graphic driver screen resolution or your graphic driver need to reinstall.
For that first when you power up the computer press F8 key then if you are able to see "safe mode" and other menu then then enter in "Enable vga mode" then go to start menu ->control panel->display ->settings then change screen resolution to 1024*768 then apply and ok.
But if you are unable to see any display when you hold F8 then connect your cpu to another monitor then uninstall graphic dreiver then reinstall.
When you power up the computer press hold F8 key for 5 times.
Let me know if you need further assistance.
Thanks for using FixYa.

Depending on the version of windows, go to device manager (the easiest way is to click start and type devmgmt.msc and hit enter. Then you look on the list for the monitor which is listed as display and then for the adapter which is listed as video adapters. If there is more than one or the device has a ! or ? next to it then you have a problem If the issue is more than one then you delete them and restart the computer. IF the issue is a ! or ? then you have a driver problem and will have to find drivers for the device.

I have a HP m7570n. How do I use a flat screen tv as a monitor


This depends on the TV's available inputs. The Pavilion m7570n has only a VGA output in the standard configuration.

Thus if the TV has a VGA port, turn off the computer and the TV. Then connect a standard VGA (RGB or D-sub 15-pin) m/m cable between the computer and the TV. To use the TV speakers, connect a 3.5 mm audio patch cable between the computers Line-out (green speaker port) to the VGA audio in. Turn on the TV and set the input to VGA (with the Source or Input button on the remote or the TV). Then turn on the computer. Windows XP should find the correct resolution to work with the TV. (If you turn on the TV after turning on the computer, you may get an unsupported signal. Press Ctrl-Alt-Del twice to restart the computer.) If it doesn't work, you may need to connect a different monitor and set the computer to a low resolution before connecting the TV and the computer.

If the TV only has composite or component video inputs, you will need a VGA to video converter (http://www.svideo.com/pctocomponent.html for example). A VGA to component cable will not work; those are for projectors that read an RGB input. TVs interpret YPbPr.

If you have added a video graphics card, you may have an HDMI and/or DVI port(s) on the card. In that case, check the specs of the TV. Some TVs will support HDMI or DVI-HDMI inputs from a computer. Others will not (since computer video signals are not the same as the signal from a set-top box). If you use a DVI-HDMI connector, make sure to use the HDMI port labeled for DVI and connect the audio cable as with the VGA connection. If you use an HDMI connection, you may need to set the sound properties to that of the HDMI port. (Find the control panel item for sound (under Hardware) and then select Manage Audio Devices. Set the Playback properties. If it doesn't work, use an audio patch cable.) Some TVs have RCA audio inputs for the HDMI-DVI connector. In that case, you will need a female 3.5 mm to RCA M/M adapter (if you use a 3.5 mm patch cable). There is a similar device if you want to use an RCA audio cable. You may need to enable the video ports on the graphics card before swapping monitors.

Some video cards have a TV out. In that case, connect the appropriate connector (should come with the video card). Then connect to the component, composite or S-video input on the TV.

Again turn off the TV and the computer before making any connections.

You will probably need to provide your own cables for must of these connection options.

I hope this helps.

I have a HP Pavilion A6403W, when I turn on the monitor the message comes up on the screen VGA input no signal and DVI no signal then it goes to sleep. CAN YOU HELP PLEASE


The monitor is telling you that it's NOT receiving a signal from the video card connected to your computer. Check the cable that goes from Monitor to Computer. Make sure it's secure. If it's secure, I would recommend you re-seating the video card, just make sure you remove power from the computer and you ground yourself. If you are not comfortable doing this, then I would recommend visiting a local mom and pop computer shop and have the technician take a quick look, should only take about 5 minutes for a decent tech to diagnose the cause.

Hope this info helps!

Compaq fp745a no input signal


Try it on another PC, check VGA cable to find out if it is PC Video card problem or monitor problem. If it is monitor, you need to open it up and inspect the components insid, look for bad parts such as caps with leaking/bulging tops.

Cpu says no input vga signal, then goes to sleep


The no input VGA signal just means that the monitor is not receiving anything from the graphic card on the tower. Is the card a digital (DVI) output card? You'll know by the connector, it's white and slightly wider than a standard VGA connector. If so, perhaps the monitor is set to the wrong input?

If that isn't the case, and the computer is using an on-board or built-in graphics controller, you could try resetting the system's CMOS settings by setting the clear-settings jumper on the system board, or simply remove the plug and CMOS battery for a few minutes. Check the computer's documentation on the exact steps to do this.

Hope this helps!
