Most likely your backlight is out, one way to tell is if you shine a light at the screen you should see whatever is hooked up to the monitor. Another issue could be the LCD inverter which supplies the power to the backlight.
The problem is not the setting on your monitor...The problem is the backlight inverter located inside the upper and lower edge of your screen.. It is busted. The backlight inverter is the light source responsible for the displaying image on your screen. If these were busted.. then the only thing you will see is black screen.
It is very risky for you to replace it by yourself if you don't have the knowledge and the right tools to open the back of your lcd..My suggestion is to bring your monitor to a credible technician to have your backlight inverter replace. if there is warranty for your lcd, please avail this.
Hope it help..
Much appreciated if you rate this solution..thanks..
Hi! there are possible reasons why your monitor shows nothing on your screen...
First, you need to check if the power cable of your monitor is well connected to a wall socket or AVR (and that you are sure there is supply output current on the AVR or in the wall outlet)
IF found that power cable is fix and secure... my suggestion is you bring the monitor to a credible technician...Because the possible reason why only black is seen on your screen, is because the backlight inverter could be busted already.. the backlight inverter which is located on the upper and lower back edge of the monitor is the light source responsible for giving image display of your lcd monitor.. Another reason could be is a deffective high voltage ballast transformer which is responsible for generating high votlage supply for the backlight....
It is too risky for you to do the repair by yourself without proper knowledge and right tools to do this.. So don't waste time consult a technician and or possible avail of the warranty if there is any...
I think what your monitor is experiencing right now is because of the backlight inverter in your lcd monitor is about to give up...The backlight inverter is a cold cathode light thats responsible for the image in your screen.. if the lights located on the upper and lower edge of the monitor will be busted then what you will see is black screen.. You will need to replace that in your monitor.
However, without the proper skills to do that and proper tools to open the monitor.. it will be risky for the safety of your monitor..
I suggest that you bring your monitor to a credible technician to replace busted backlight or (burned high voltage ballast transformer - supplying current to backlight)
There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc. http://en.wikipedia.org/wiki/Capacitor_plague Please post back what you find.
That's right, the problem is related to inverter, but source of it - backlight lamps (if you see an image for fractions of seconds) or MOSFETs (if you see an image for few or more seconds). Image shows up, that means inverter starts, but then goes off because inverter controller turns into protection caused by something. Checking lamps is not that hard. Disconnect all cables coming from the screen and remove chassis with PCBs, so you will keep the display itself only. Next, at the edge where high-voltage wires are coming from, there you will see tiny philips screws, take them off. Then gently and very straight pull lamps assembly off the display, one and then another. If lamp is bad you shall observe contrast black ring or black dots near to the electrodes. Bad lamps must be replaced, you can buy them on ebay, for instance, just search CCFL 19". Or, if you don't care about total brightness, you can substitute faulty lamp with 27 pF 3kV capacitor, soldered across appropriate HV-connector on the inverter board - this will work also.
Yes, It sounds like the backlight inverter circuit is shutting down. No inverter power, no backlight. On some monitors the inverter circuit will shot circuit the power power supply which makes the power light flash on some it just kills the backlight. You can usually check with a flashlight. Hold the flashlight pointed at the screen and see if you can see any of the icons or background picture. If you can then it is the backlight circuit or backlight tubes, usually the circuit.
Yes, this is a backlight problem. However, it could be either the light itself or the inverter that powers the backlight when it fails like this. I'd recommend replacing the entire screen plus housing and hinges (it is often sold as a complete unit) or just replace the inverter (often relatively cheap) and then if that doesn't fix it replace the screen (the backlight is non-replaceably attached to the screen).
The other option is to simply attach it to an external monitor and use it like that. This is also a free way (well, as long as you know someone that has a monitor) to make absolutely sure that the problem is the screen and not anything else.
HI. I had the same problem with mine. It would flash the screen on for a split second and then turn black, the whole time the power light remained green. Upon opening up the case, I pulled the combo power supply board/inverter board out for inspection. I noticed one of the capacitors had a bulge on top indicating it was bad. It was the the 680uf 25v capacitor. I desoldered it, and soldered in the new one. After hooking everything back up, bingo!! Monitor now works perfectly. I couldn't find an exact match to the capacitance locally, but I had a 1000uf 35v cap in my utility box. It worked fine as a replacement. You can usually go within 30 percent of tolerance and be alright. Just don't go under on capacitance or voltage. I hope this helps.
