How to troubleshoot a system that boots up but wont display


  • VGA cable replacement
  • Needle-nose pliers
  1. Power downthe computer. Check the VGA cable running from the computer to the monitor. If the cable is not snugly seated in both ports, the video signal will not reach the monitor.
  2. Check the connector on each end of the VGA cable. Examine the nine pins on each connector. If any of the pins are bent or broken, the video signal will not reach the monitor. If there are just a few bent pins, you maybe able to straighten them with a pair of needle-nose pliers. Be careful not to break off any of the pins. If any of the pins are broke nor missing, you will need to replace the VGA cable with a new one.
  3. Disconnect all cables and peripherals from the computer. Open the computer case by removing the Phillips screws along the side or back of the case. Remove the cover or side panel to expose the internal components. Locate the VGA card and make sure it is fully inserted into the PCI card slot. If the card is not installed correctly, the video signal will not reach the monitor.
  4. Close the case, reconnect the power cord and all cables, and power up the computer. The video signal should display on your monitor.

PC is not communicating with the monitor.


Are you using the DVI or VGA cable? You might try the other if both are supported by the computer. With the VGA cable, it's quite easy to bend the pins within the plug. Unplug the cable and look at both ends to see if the pins were bent during insertion. If so, you might be able to straighten the pins with needle-nosed pliers. The carefully plug in the cable again.

reversed cables and blew a fuse. how do i get it out???


I think the needle nose pliers may be best. insted of grabbing by the thin sides, grab it the wide way and gently rock it back and forth. I think this is like a 35 amp fuse, so the holder has to be very tight to keep a good connection. I have one of these, and for two days I thought it was bad untill I pressed the red on button.

how to change throttle cable on 2005 rm 125


The carburator end...you will need to remove the seat and gas tank.The top of the carb will turn off counter clockwise, then you can pull the "slide" up out of the carburator. Note which is the front for re-assemble. There is a spring between the slide and cap, and look into the slide to see if your cable clips in, or may have a phillips screw and plate to remove to get the cable free. I use needle nose pliers to hold the spring back to remove and replace the cable.
The throttle end is easier. Remove the plastic cap and unthread the adjusting worm nut. The cable end "ball" will come out with the help of needle nose pliers also. Pull the cable slack up to rotate the "ball" out of the throttle tube.
Hope this helps!
