Question about Computer Monitors

CTX S762G power on but nothing is showing up on the screen

Monitor powers on. No CCFL lights are on, just the green "on" light. after about 5 seconds, the CCFL tubes flash (still with nothing on the screen) and then the whole thing shuts off. It will keep going through these cycles until the plug is pulled.

What is causing this?

    Actually it was bad caps on the psu board. i replaced those and presto. Inverter boards are usually alright...it's the fact that if a cap is bad - it pushes WAYY too much power to the inverter causing the CCFL tubes to not come on.

    when i plug the monitor in, the green power light comes on, then it flashes on and off nothing on the screen, until i unplug it

    I've replaced the suspected caps but still got the same blinking power indicator. 12 Voltsdc coming from psu line to video card. I disconnected psu and connected a 3 amp 12 volt dc external supply and the monitor works.

My lcd screen switch goes green and a message appears "going to sleep" and the switch light goes yellow


1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or flashing, but nothing displays, borrow a monitor from a friend. If that works, your monitor needs replaced.

The fault could be a faulty inverter board that supplies high voltage to the CCFL lamp or the CCFL lamp is faulty. The CCFL lamp is a mini fluro lamp that provides the back lighting for the screen.

I have 2 of these monitors with the same problem. On power up the green led will light & remain on but the screen remains black. On one of the monitors the screen will light up for a few seconds then...


The inverter that turns on the back light may be bad - it's suppose to create the high voltage pulses to fire the CCFL back light lamps. Apparently the back light turns on after a few seconds however, it cannot stay on because the inverter might be bad. If you connect a known external CCFL lamp to the to the inverter output you can isolate the inverter.

Monitor backlight problem (Dell S2409W)


pa_ma_fi, Have you figured out how to do the flashlight test on you monitor when it's lcd panel turns black or blank n black. No, CCFL back-lit lcd monitors require lots of things to be working all together at once to light up the CCFL tubes. The new style curlie-Q screw-in, energy efficient CFL light bulbs are of the same similar technology and use an "electronic-ballast" circuit to "light-up" the lamp! You will need to check to see if pc is working perfectly with old monitor that you know is good. You should do some free reading here at fixya in my and other fixya ccfl back-lit lcd technicians profiles. ou will also need to visit YOUTUBE for "LCD monitor disassembly" and "LCD monitor repair" videos. May need printed circuit board "switch-mode-power-supply/ ccfl inverter supply " to be repaired If pc software/firmware has been determined not to be causing this on/off/on/off symptom.

Monitor turns on and screen comes up for about 1 second and then turns black. Green power light stays on and green


This will be a fault with the inverter section that powers the ccfl lights usually a transistor or an i.c replaced will cure the problem

I have two CTX monitors.


well by ordering the caps replaced that is a start for the first one it should work like new when you get those replaced, second monitor it could still be a cap issue but you need to look and see if they are doomed if hey are popped then they need to be replaced, one of the reasons they shut down is variance in the power supplied to the ccfl if it variances too much the unit shuts the vga and thereby the ccfl unit off.
fyi you don't need all the caps replaced just the popped ones.
