Question about KDS Radius RAD-9 (Black) 19 in. Flat Panel LCD Monitor
I have two monitors and all of a sudden one goes black after 5 seconds. I have checked all cables, switched cables, swore a little and nothing seems to work. I can turn it on, light turns blue, beautiful screen and wham - it is out and blue light it still on! Help. The other monitor is working fine. I can faintly see whatever I have put on the screen when it goes black. Any information you can give me would be very helpful. I have a DELL computer, ATI Graphics card 2600 xt, running the wonderful Vista OS. Thanks
My monitor does the same thing at times and sometimes shows "No Signal" and at other times the screen will maintain the images but the backgound color switches to mustard yellow. In each of these cases I have been able to solve the problem by unplugging the power cord from the electical outlet for about three seconds and plugging it back in. I have a KDS model 780 LCD.

You have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of he monitor. If you are good at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htmYou can take the back cover off your monitor and look for the bad parts,replace any that look like the pictues and your monitor should work fine. The capacitors do need to be installed with the correct + and -connections, note the stripe on the old one and insert the new one the same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping. I hope this helps, if so please rate my solution.

Do you get the 5vdc for logic circuits and 12~18vdc for the inverter circuits. Please recheck your soldering works, make sure the caps are installed with correct polarity. See some of my examples here: http://s807.photobucket.com/home/budm/allalbums

Testimonial: "your advice has been helpful but i need more advice my 15v caps are good"

The most common problem with LCD monitors is the capacitors that are on the power pack. the pack usually looses or pops as we say 2-6 of them after 3-5 years. its almost a certainty after 5 years. a component repair tech can replace these but unless you can find some one like me who will do it for cheap to save the landfill you most likely will buy a new one.
