Monitor blacks out after few seconds

Haven't used computer in few months since IDE cable was messed up. Bought a new IDE cable today installed it and started my computer, when i started i could see my screen come on for a few seconds (Saw words and everything else) and then went black and my monitor went on standby.

Got on my laptop and plugged my monitor up to my laptop and monitor worked fine.

Plugged my monitor back into my old comp (Desktop) and once again i started it and it showed words for a few seconds then blacked out and went on standby and said ''No Signal'' Don't know what is wrong would please like some help! Thanks

I have post on my link how to simply troubleshoot that..

but by the way.. here are some tips that you can do..

first check your CPU if it is still running after the monitor is black out..

if it is running it means it is not your power supply.. but im not telling it not that totally..because maybe your power supply is malfunctioning...try to remove the memory and then clean the connections of the memory..the coppers i mean..then put it again in place properly... try to open your pc again.. if nothing happens try to contact me at my ym...stormblade002@yahoo.com..

Since you opened up the PC the first thing to do would be to make sure the graphics card (if it is a standalone card) is seated properly. Remove it, blow out any dust, and re-install it. If that does not fix the problem, or if the graphics are built into the PC, try getting a cheap video card (or borrow one from a friend) and that should fix the problem, since you have ruled out the monitor as the problem.

Also, it could be a problem with the power supply. I'd chase down the graphics card side first though. If that doesn't work, try the same procedure with the power supply.

Note: I have run into instances where an AGP slot got "zapped" by someone opening the case and not taking proper static precautions, so be careful, always unplug the PC and ground yourself to the case before touching anything. If you try a video card you know is functioning and it still doesn't work, pick up a PCI graphics card and see if that works.

Hi i bought WD 320 gb sata /8mb hard drive - the cable ribbon on my dell 4600 does not plug into it! do i need a different cable yes


Hi,
Generally speaking, we have two types of hard disk interface. IDE (the old one with ribbon cable) and SATA (with a 1cm strip like cable).
As your new hard disk is SATA, you need a SATA cable to connect it to you PC.
Below are a few images which would help you.

My hp w2007 monitor keeps going to sleep mode when turned on with the computer on


I'VE BEEN HAVING THE SAME PROBLEM FOR MONTHS - SOMETIMES THE MONITOR WILL BE FINE FOR A FEW DAYS AND OTHERS IT WILL NOT COME BACK ON NO MATTER WHAT I DO. HOWEVER, I FINALLY FIGURED OUT THE PROBLEM AND THUS A SOLUTION AND IT ACTUALLY DIDN'T COST ME ANYTHING.

MY CPU DOES NOT HAVE A VGA OUTPUT SO I WAS GOING TO GO BUY A VGA/DVI CABLE ADAPTER BUT INSTEAD I FOUND A VGA/DVI ADAPTER IN THE BOX THAT MY COMPUTER CAME IN. I ATTACHED IT TO THE DVI CABLE THAT I ALREADY HAVE AND PLUGGED THE DVI END INTO MY CPU (SINCE IT ONLY HAS A DVI AND NO VGA OUTPUT) AND THEN THE VGA ADAPTER END INTO MY MONITOR AND WA LA... IT WORKS NOW AND HAVEN'T HAD ANY PROBLEMS WITH IT GOING TO SLEEP.

WHAT I IMAGINE IS HAPPENING IS THAT THE DVI OUTPUT ON THE MONITOR IS FAULTY - EITHER FROM THE FACTORY OR THE PINS HAVE BEEN DAMAGED SO MY CABLE WAS NOT WORKING CORRECTLY. IN TRYING TO FIGURE OUT WHAT WAS WRONG, I BOUGHT A BRAND NEW DVI CABLE AND IT STILL DIDN'T WORK SO I KNEW IT WAS NOT THE CABLE. THAT NEW CABLE WAS RETURNED TO THE STORE FOR A REFUND!

My son moved the monitor from one pc tp another and it worked great for a few days. Today he turns it on and the screen is black and blinks every couple of seconds. I have restarted, unplugged and checked...


Guess to narrow it down, can he put the monitor on another computer to see if it still works? Also putting different monitor on the current computer might give you a few more ideas. At least then you will know have a better idea of where the problem lies. Hard to diagnose this stuff unless you are the one sitting in front of it.
Hope this starts you in some direction.

I started a thread on my own forum because there is a lot of discussion about this on many forums with no responses from HP and no one seems to mention that they got a replacement despite the massive problem that it is. It is out of order and I don't doubt for a second that HP knows the length of life of the components in their monitors. All of these things are tested and your talking about components used for years. They know the score by now.

Hello,

It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of the monitor. If you are good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.

I hope this helps, if so please rate my solution.

Monitor goes black for a few seconds


Try swapping the monitor cable from the working monitor to the other video connection on your computer. Effectively reversing the connections to isolate whether your problem is the video card in your computer or the monitor itself. If you find the working monitor displaying similar symptoms, then check your video drivers and ensure that you have all power saving features, screen savers, etc... turned off.

This is usually a bad capacitor problem. They would need to be replaced, or get a new monitor. Some shops will work on them, but you have to weigh the cost vs buying a new monitor for almost the same price.

There are some websites on repairing your own, but you need to know a bit about soldering and such.
