Re: pavilion a288n video loss
Check your memory. Memory is one absolute sign for no video. Also check the pins on the video plug to make sure none are bent or broken. You must make sure the pc is turned off when doing these things. And make sure your video card is seated all the way down. No gold showing outside of the pci slot. Also you can try another pci slot. Sometimes they fail. You can also try plugging your pc and monitor into another wall outlet. Believe it or not it is not uncommon that one wall socket will put out more power than another. I've seen it 1/2 doz. times myself in older houses.
If none of these suggestions work & you don't mind letting me know I could give a few more in depth possiblities to try.

The monitor is NOT receiving a video signal from the PC.
You could try a different monitor, but it is likely your graphics processing unit (GPU) has failed.
If your monitor plugs into the motherboard for the graphics signal, then you can purchase an 'ad-on' video card for your PC that will allow you to continue using that PC. Video cards come in a variety of shapes and sizes so you need to know what 'slots' for ad-on cards are available for use and how much your budget is. According to google, that model has onboard AGP graphics, so it will have PCI slots (do NOT confuse this with PCI-e they are NOT the same.) This is, (like the rest of your PC,) very old tech and there are sadly, not a lot of choices out there for PCI video cards. Basically, the ones left are the ones no one else wanted to buy....you are better-off calling local PC shops to see if they have any used cards for sale. You don't need anything more than a 32MB or 64MB card at the very most.
if you already have one, and are using it, then power everything down and unplug the power cord. Press the power the power-button for 5 seconds to ensure complete power-drain from the system. Completely remove the video card and blow-off any dust. Inspect the card for blown-capacitors, if none found; re-install the card, and reconnect everything and try it again.
If you know your monitor works then the likely culprit is the on-board video could be bad. If you can give me the model # of your computer or if it's a custom computer, the model # of your motherboard, I can let you know what kind of video card your computer takes and what brands to stay away from.
Good luck and hope this helps. If it does, please vote! Thanks!
Make sure the cable is in good on the back of the computer and on the monitor. If the cables are in good, then either the monitor is bad or the video card is bad. Try using another monitor on the computer. If the other monitor gets a No Signal then the Video Card is bad. If the other monitor shows a display and works, then the original monitor is bad.
If you are certian the pc is powered on, check the video card and any new card that has been added to the pc. If you have a video card installed, remove all other cards and retry your boot. If you still have no video, replace the card. If the video connection is on the board and you and have added a new video card, use the "old" connection to open your operating system and configure the video setting to use the new card and change connection. Good Luck, C2Solutions
One quick thing to check is to see if your Video card is fully seated down in the motherboard? Sometimes they can pop up a bit, and you lose your output.
If that doesnt help, you could remove your memory, one stick at a time, to see if that helps. This could be the cause if you added memory from the old computer.
what resolution are you setting your screen to? if you are setting it too high or to a resolution/frequency that your monitor doesn't support, it will do this. Try setting it to 800 x 600 w/ 32 bit color and a frequency of 60Hz. If you do this and the monitor still blinks, you may just have a bad DVI cable.
First things first, try the monitor with other computers.. If the monitor is functioning then there must be something wrong with the VIDEO CARD or BUILT IN VIDEO ADAPTER for the computer. My guess would be the video processor is not working and one probable solution is to purchase a new video card.
Second Case: You might have changed the video resolution into something it cannot display. Like setting a 1280pixels x 800 pixels @ 32 bit. to a 15" monitor. 15" monitors or any other monitor in this case may not have support for higher graphics. Stick with 1024 x 768.
Solution: Reboot the computer on safe mode and set the necessary display settings to the lowest.
