If you can, try your monitor on another PC, neighbough or friend if necessary. If it fails, you've a monitor problem, if it works you've a PC problem. Oh ensure you use the same leads each time.

If its the monitor then its a replacement or repair, if its the PC, it could be just the graphics card needs reseating or replacing. Not too expensive if you're not into CAD or gaming. You could try second hand but make sure its compatible with your motherboard.

Here is a link to a repair guide for the LG L196WTQ. It sounds like you have a power supply failure and the guide shows how to open the unit, check the power board and then what to replace if you do find bad capacitors.

Problems like wavy or flickering picture, flashing power light, slow to display the picture or no power at all are all symptoms of a failed or failing power supply board.

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

The power printed circuit board is failing, not
delivering the proper power to the main board and/or the back lamps. One can
have this board repaired inexpensively by a electronic technician. Email me at Sprint6@zoominternet.net
and we may be able to get your unit working properly again.

PC will not power up. No fans, lights, anything.


Have you tried a different power cord? (longshot, I know, but it is one of the variables that you don't mention)

Have you tried a different A/C outlet?

Monitor on power save mode and using wireless keyboard and mouse


This sounds like the monitor is not reading a signal from the computer. I had the same problem when I installed a DIV cable from my old VGA cable. The video card was still sending the signal via VGA port instead of the DVI port of my video card. You should cheack the cable to you're computer and what port is being used. If everything is hooked up correctly then there might be a problem with the cable. Other then that it could be you're video card. If the hard drive is running and everything is running fine then what I said should be whats wrong. If nothing works go back to the shope and tell them the new problem you have.

Monitors comes on for a few seconds then goes black. the only way is to turn it on and off but still only stays on for a couple for seconds


I think the power board might be going bad in there. Hook up a different good working monitor to the computer and see what happenss.

If the monitor still turns off after a few seconds then you know its the video card acting up. If the monitor stays on then you know its the original monitor that is bad for sure.

Power light goes out but power remains thru the m-board fan runs


you need to replace the power supply. The fan sound is the fan for the power supply and not the computer. for cheap parts or used goto headgap's. They know what you need and probably even help you replace it yourself.

System turns on however hard drive will not cycle nor will mouse or key board activate


Turn power off and unplug power from computer.
Unplug printers,backup drives and speakers.
Open case and unplug power supply from the board.
plug power cord back in press the power button.
Of course nothing will happen.
unplug power cord again.
plug power supply back into the board.
plug power cord backup and press power switch.
If nothing happens unplug power cord again.
pull out your memory sticks and plug cord back in and press power button.
Of course not much will happen.
But really something is happening to your computer so continue.
Pull power cord and replace memory sticks.
replace power cord and press power switch.
Continue this pulling out pci cards one at a time until you find out what the problem might be.
Try different keyboards and mice too.
Good Luck
