Radius S-3F works properly but will not display pc data

1. Check to make sure your monitor is on! Some monitors have more than one power button or switch - check to make sure they're all switched on.Check for disconnected monitor power cable connections. Your monitor might be working fine and your only problem may be a loose or unplugged monitor power cable.Note: A disconnected monitor power cable could be the cause of your problem if your monitor's power light is completely off.Check for disconnected monitor data cable connections. Again, your monitor might be turning on without a problem but no information can get to it because the cable that connects your monitor to your computer is disconnected or loose.Note: A disconnected monitor data cable could be the cause of your problem if your monitor's power light is on but is amber or yellow instead of green.Turn the monitor's brightness and contrast settings completely up. Your monitor might be showing information but you just can't see it because these display settings are too dark.Note: Most monitors today have a single onscreen interface for all settings, including brightness and contrast. If it turns out that your monitor isn't working at all then you'll likely not have access to this interface. An older monitor might have manual knobs for adjusting these settings.Test that your computer is working correctly by connecting a different monitor that you are certain is working properly to your PC. Your monitor may be working fine but your computer might not be sending information to it.If the new monitor you connected does not show anything either, proceed to Step 6.If the new monitor you connected does show information from your computer, proceed to Step 7.Important: When testing with the new monitor, make sure you use the data cable that came with it and not the one from your original monitor.Determine why your computer isn't sending information to your monitor. Since neither monitor works, you now know that the computer is not sending information to the monitor. In other words, you've proven that your computer is the reason that nothing shows up on your monitor.Chances are your original monitor is working fine.Test your original monitor with a monitor data cable that you know is working. It's possible that the monitor itself is working properly but it can't receive information from the computer because the cable that connects the monitor to the PC is no longer working.Note: If possible, test using the data cable from the monitor that you successfully tested with in Step 5. If not, purchase a replacement monitor data cable to test with.Note: The data cable on some older monitors are permanently connected to the monitor and are not replaceable. In these cases, you'll have to skip this step and proceed to Step 8 Replace the monitor.

Open your computer and discharge static by holding the chasis casing of your system unit for 1 minute. Then start cleaning your video and memory card and also the their slot by using vacuum cleaner and small paint brush. Then put it back again and test for a display. Most of the time because of the dust covered the slot or the pin of the video and memory so the system did not detected that hardware that is why those hardware will not functioning. Clean and test have a nice day!

why not try a dead display on 2 machines 2 PCs
using only 1 data cable at a time why try to confuse it????????

the OSD must work, or the display is bad or the power supply to it is dead.
easy as apple pie.

the monitor has a tiny computer inside it (micro)
on mine, the data lines dead shows NO SIGNAL in the screen
every time you I power up my monitor with data cables pulled off.

best is to read the book for your monitor, and run all the tests it
tells you there,

A number of things can cause "No Signal" on a monitor

1) Check the cable between the monitor and PC is properly connected
2) If the PC has more than one display port try changing the display port the monitor is plugged into
3) Try an alternative cable between the monitor and the PC
4) Check that the correct input is selected on the monitor

Time Required: Testing a monitor could take from a few minutes to much longer depending on the cause of the problem Here's How:

1. Check to make sure your monitor is on! Some monitors have more than one power button or switch - check to make sure they're all switched on.
   
2. Check for disconnected monitor power cable connections. Your monitor might be working fine and your only problem may be a loose or unplugged monitor power cable. Note: A disconnected monitor power cable could be the cause of your problem if your monitor's power light is completely off.
   
3. Check for disconnected monitor data cable connections. Again, your monitor might be turning on without a problem but no information can get to it because the cable that connects your monitor to your computer is disconnected or loose.
   Note: A disconnected monitor data cable could be the cause of your problem if your monitor's power light is on but is amber or yellow instead of green.
   
4. Turn the monitor's brightness and contrast settings completely up. Your monitor might be showing information but you just can't see it because these display settings are too dark.
   Note: Most monitors today have a single onscreen interface for all settings, including brightness and contrast. If it turns out that your monitor isn't working at all then you'll likely not have access to this interface. An older monitor might have manual knobs for adjusting these settings.
   
5. Test that your computer is working correctly by connecting a different monitor that you are certain is working properly to your PC. Your monitor may be working fine but your computer might not be sending information to it.
   
   • If the new monitor you connected does not show anything either, proceed to Step 6.
   • If the new monitor you connected does show information from your computer, proceed to Step 7.
   Important: When testing with the new monitor, make sure you use the data cable that came with it and not the one from your original monitor.
   
6. Determine why your computer isn't sending information to your monitor. Since neither monitor works, you now know that the computer is not sending information to the monitor. In other words, you've proven that your computer is the reason that nothing shows up on your monitor.
   Chances are your original monitor is working fine.

   WARNING: A computer monitor is not a user serviceable device. In other words - do not open the monitor and attempt to repair it yourself. If you would rather have your dead monitor serviced instead of replaced then please let a professional do it.
   

check the monitor connector from the pc if the connection is good. check the display device..VGA

sir if u really love your computer, then take it to the nearest dealer. The problem is might be with the capacitors.

But my suggestion hence, is to isolate the power board (the one that has the socket for the power input), check if any of the capacitors (the tall cylindrical structures) have bulging tops, if they do, try to replace them (Novices please bear the polarity in mind when you play with capacitors) with ones with higher rated ones (especially the voltage rating, normally these would be rated for 25 volts, so try getting one that is one step higher.

Open up the set and look for bad caps, see some failed monitors here: http://s807.photobucket.com/home/budm/allalbums

I assume it has speakers built in since your post is in the monitor category. You need to connect the speakers in the monitor to your sound card. It should have included the audio cable to do so. The cable should have a green plug and it plugs into the green jack located in the back of the computer.

whats up with blackscreen?
