Rita...Unplug the computer, take your BIOS battery out (make a note of which side is facing up!), wait 15 minutes, replace the battery (make sure it goes in the same way it came out, do not reverse polarity by accident) and reboot. Does that help? If you had this work done on your computer by a service, contact them with this problem. They should have tested the unit before sending back to you.
From what i can see your compaq presario has both hdmi and vga outputs the panasonic viera you have both a vga and hdmi input. Therefore you can use both a vga lead or a hdmi lead. Hdmi also outputs audio therefore it is probably a better choice.
In most cases the answer is "YOU CAN'T DO THAT".
The output from a computer is not a signal that a regular TV can interpret as an image, unless your TV has an input similar to a computer's VGA or DVI port AND the TV's manual says that you can do that. Otherwise, you're out of luck
Could be the monitor or your Presario's VGA card. Swap the monitor with another system to see where the problem lies. If another monitor works on your system , it's your monitor. If another monitor doesn't work, then the problem is the VGA card.
If the question is can I convert my composite video output to a super video input then the answer is NO,
The composite is coaxial (2 wires) the S-Video uses 4pins and there is no S-Video output on a Presario 1200 laptop.
You can however use a Multi-AV SCART adaptors with Input/Output signal switch where you plug in the composite video output into the top video and 3.5 mm jack stereo audio into the mono audio connections on top.( via a stereo to mono cable)
from what you have described it appears that the onboard video might have malfunctioned,there is no way to replace it, you can however go buy a video card from your nearest computer retailer. you just want to make sure it is compatible with your machine. on another note from what your saying the keyboard is donig i would be wary about spending to much $$ because it could also be your motherboard
The monitor is telling you that it does not see the computer. First, remove the monitor cable from the back of the computer, check for bent pins on the connector and replug in the connector. If that doesn't work, try swapping to a different monitor to see if it sees the system. If this works, you have a bad monitor or monitor cable. If that doesn't work, open up the computer remove the video card, clean any dust from around the card and socket and replug the video card. If these ideas don't work,get back to me and we'll go from there. Have a good day! Ron
If it was your video card, you would have no picture at all. Try to boot in safe mode and do into your options and make sure your hibernation is not on. Only other thing I can think of, it could be *********** board.
