Question about KDS Radius RAD-9 (Black) 19 in. Flat Panel LCD Monitor

Open Question

Monitor goes on and 5 seconds later goes black

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

SOURCE: kds model 780 monitor no signal, power button does not work

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.
GOOD LUCK

Hello,

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

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.

I tested in my PC with the cables of my own monitor (Benq FP92Wa) and the image pop-up just fine, but after 5 seconds the monitor goes black. I tried to reboot in safe mode but the same thing happens


If the monitor has the same problem on two different computers, it is most likely the monitor has a problem. This monitor is probably about 9 years old, and it would probably cost more to fix it than to buy a new one.

Monitor goes blank less than a second after turning on.


Sounds like either there is a bad connection from the computer to the monitor, or the monitor has a faulty power regulator, causing the monitor to overheat prematurely, and shut off.

Why does screen go black after a few seconds


Hope this helps.... Your monitor has an inverter issue. You know it's an inverter problem when:
1. Your monitor starts normally and displays the startup/desktop screen for a while.
2. Then it suddenly goes off, leaving a blank (black) screen or a very dim display.

To fix this black screen problem, change the inverter board (based on your monitor brand).

Monitor works ok then suddenly loose picture(black screen) turn monitor off then turn it back on works for approx 5 secs then goes back to black screen


there are many reason why a monitor suddenly turned off then back to work again , over use may over heat that cause the soled parts on the printed board of your CRT go loosen , try to re sold it, sometimes your PC might stop viewing so the monitor automatically shot off stby mode , loose connection due to basted parts , capacitors,power regulators,resistors , even the cables also might be.

My monitor works fine for weeks than suddenly just goes black! I turn it off and back on and it only stays on for about three seconds than goes black again! The power light stays on!


take off the monitor data cable from pc and try to turn monitor on if appears a smal square on the screen that mean your monitor is ok , and the black screen reason maybe data cable or vga card.

note : your monitor resolution is 1680x1050 some times wrong resolution cause like this problems

Hi, my BenQ FP72G 17 inch LCD Monitor keeps auto-adjusting every 5 seconds and every now and then it will turn itself off and later go on again. Any help ?


Make sure the cables are in well with a good amount of slack, it can cause a problem if your power cable or computer to monitor cable is loose

Used as second monitor suddenly stared to go dark


If the screen is lighting up for a fraction of a second when you turn on & then goes dark, this indicates a fault either with the backlights on the screen or the inverter part of the monitor. You can check the backlights if you have access to a backlight tester, you need to remove the rear cover & connect the backlight cables into the tester, if this checks ok then look for a problem on the inverter board, checking the capacitors for any signs of distress.

AL178 17in. Flat Panel Problem: Screen goes black after about a second


hi,
I had the same problem before. I open my set to find out the faulty component are at power supply main board.
I change the electrlytic capacitor 680microfarad and a resistor burnt near the FET.
You can visual check first.Color changes and bulky form on cap and burnt resistor easily.
Have a try.

Monitor goes black with a white horizontal line across the middle of the screen


Check to see that the monitor cable is correctly installed. Also, make sure you have the most up-to-date drivers installed for your graphics adaptor card(both ATI and Nvidia carry catch-all driver programs to keep you up to date.) Tighten the cable screws of course, to make sure the monitor cable isnt just wiggling in its seating.
