WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Test all power and data leads that attach to your hard drive IDE,SATA the leads from your (motherboard to your hard drive) make sure they have secure dust free connections and are not faulty if its a 40 pin flat ribbon type it will be the first to fail make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even something as small as a faulty electrical fan and its lead can cause you problems computers need all power and data to continue through every working device and to have an end so any faulty leads will end up with a computer error Check your RAM. The RAM is located in the middle of the motherboard. There are tabs that you can push to release the RAM. Remove it and put it back in place until the tabs pop out. Loose RAM can cause your computer not to start properly where you want to see a video signal.

Make sure your graphics card is securely seated with no dust built up or in the socket if you remove your graphics check the socket to make sure its dust free Restart your computer then reinstall it this should activate found new hardware wizard Check the vga lead for secure dust free connection or try another vga lead. Hope this helps.

Hi! i have hitach CRT tv has a problem of switching. the power supply is okay but there is no horizontal signal.I have changed the video amp TDA 8362 but still the same problem.


You need to check if you have horizontal drive to the base of the horizontal out transistor. With a scope check the primary and secondary of the horizontal drive transformer to find out where you are losing the drive.

Monitor goes blank after short time


One of two things are happening here. Either there is a problem with the cord and/or electrical connection or there is too much dust in the ventillation holes on the monitor and its over heating. If you have not changed the power cord, then try relocating to a different power outlet. Then clean out the ventillation holes with a can of spray air and dusting.

Monitor not recieving signal?


Hello,
If you are really sure that your monitor is working, then you would probably have to change your graphics card with a working one to see the results. That should solve your problem. If this does not solve your problem, then we are not dealing with a display problem here. In this case, you may have to check your memory.

All the best.

Power Supply and Video keep going out.


I would suggest that you try and check the system with another power pack, just to be sure that it is not the power supply that is faulty.
This is because what you have describe here is one of the symptoms of a failing power supply, and It is not always advisable to take a power supply case lightly, and when it is detected that its the one that is faulty, Just change the power pack OUTRIGHT! and please don't think of repairing it. It is not always expensive though, as compared to if your whole system now starts to develop fault because of it.
Hope this helps you out.
Goodluck.

Lighting came into my computer via the ethernet cable. can this be fixed I also think it took out my power supply un it. It is a gateway 500c.


If only power supply's affected, then change the SMPS with a compatible one of the same rating. But first check the monitor by connecting to the mains power supply with the video chord not attached to anything. if the monitor displays "no videos" signal, then the monitor is OK cange the SMPS of the CPU and check UPS & spike boards fuses, otherwise commect to main power supply pluf(Wall 3-pin outlet socket)......sodeep
