Hello,

If you can solder you may be able to repair your power supply. We have some pictures and repair guides on our web site at:
www.ccl-la.com/badcaps.htm The pictures show what bad capacitors look like, you can take a look at your power board and see if there are any bad caps on it. If so if you replace the caps you should be back going. If you want to send us a few pictures of your boards in the monitor, taken as close and clear as possible I may be better able to spot the problem caps.

Well, if you are satisfied that your computer works just fine with another monitor, then you could rightfully assume that you need a new monitor.
You answered your own question.

    Hey--sometimes you try and try to solve a problem and suddenly you realize you solved it without knowing it. Happens to me all the time.
    You can get replacement power supplies, but I'm thinking that it might be far easier to just replace the monitor.
    You can try places like National Parts Depot at 800-524-4800 for a starter . There is also Spareparts Warehouse at 877-253-8898

    Ok, I've now had 2 different Dell SE198WFP monitors with the same problem and I had to read numerous posts on numerous blogs looking for a solution before I actually figured it out, everything that I’d read suggested bad capacitors on the inverter board (and I’m sure that’s an issue, but it wasn’t mine). After replacing all of the caps on the inverter I still had the same problem.

    Long story short, I found (on both of my SE198WFP monitor’s) that at least one of the four CCFL backlight tubes had a burnt wire on the end of it. Period.

    Now I’m not sure if this is a common problem with this monitor, but it was in fact the problem with both of mine and after fixing these wires both monitors now work just fine :-) It seems that all four CCFL’s have to pull the same amount of current or the monitor trips the overload and shuts itself down. I hope this helps!! And good hunting :-)

My asus vw193D-B shuts down


Check cable. It's not communicating with PC video card. It should pick up the input port, but make sure on monitor. You can try re-seating video card. Also test with VGA if you are using HD like HDMI.

Dell SE198WFPf backlights go off after 2 seconds after power on. You can turn it off, then back on again and get light for 2 more seconds, then back off again. Light stays blue. Not a problem with the PC....

I have a Dell SE198WFP Flat Panel Monitor, screen goes black?


The LCd panel may be damaged and will cause this problem.

Another thing is overheating of the GPU.

The LCD signal receiver can be goign on you.

The is also the possibility of a faulty inverter.

Only thing to do is service or replace. Test the unit on another computer, if you don't get the issue there then you know its a problem with the PC.

MONITOR COMES ON FINE I GET A FLICKER AND THE SCREEN GOES BLACK


Hi,
 
It’s very likely your monitor has failed. Most Dell monitors have a 3 year warranty, so if you got it before three years, you could get it replaced by calling Dell. If you got the monitor with the computer, you can check your warranty online from with your computer Service Tag from http://support.dell.com/support/topics/global.aspx/support/my_systems_info/details?c=us&l=en&s=gen . If you bought the monitor separately, you would need an Order Number or Customer Number for the purchase, or you could call Dell support and they could pull it out with your registered phone number. Dell would also need the serial number (starting with CN XXX..) from the back of the monitor.

Hope this helps. Please rate your feedback!
Thanks,
