Help with a monitor problem.

by dadude1083 Jun 8, 2007 8:04PM PDT

Hi guys, first time poster with a problem.

So my KDS USA model 17SX monitor just went dead the other day. The screen went black, and when I try to power it on the green power button just blinks and blinks.. How can I find out if I just need to replace the external power supply, or if its something worse? Anybody have any guides out there on what to look for in a "fried" monitor?

Any help would be greatly appreciated.

Thanks!

Not much user serviceable in that.

The power supply brick is tested with a Volt Meter. I have to decline teaching how to use such here but any 1st year electronics high school student (most!) would be able to help you use it to see if the power brick is ok.

Test the display on another machine and test another display on your machine to figure out where the fault is. Sometimes the PC died and not the display.

Well, I have a Volt meter handy but no clue how to use it (brother in-laws). Guess I can do some google searches to find out if that is the problem or not. Anybody know what to look for on the inside, now that I have taken it apart though? (Fried chips, broken circuts, etc.)

Since it is the power light that blinks, I suspect that the power brick is OK. I would say it is more likely that your video signal is either not there or out of range.

First check to make sure your cables are all in place. Then restart your computer. If you notice ANY signals or status coming up on screen then that tells you the cables are probably connected. If you can actually read any of the data - for example before you get past the POST (Power On Self Tests) and before Windows, then that means your cables are probably connected right.
If all that display goes "KA-flooy!" (a technical term meaning terribly wrong) then chances are your video drivers are giving you a problem.

If you do suspect the drivers, for whatever reason, you should be able to start up in Safe mode, which uses the basic Windows VGA (640x400x16 color) mode, which every monitor should support. Safe mode will allow you to remove the bad video driver and then you can install a newer or better one.

Good luck.
