Flat Panel Monitor the power button flash

When I turn on my Flat Panel Monitor the power button and the lower edge on the screen starts flashing. The screen doesn't display anything. I replaced Power and Monitor Cables , I connected the monitor to another computer that had the same flat panel... the trouble followed. I'm using a different and it is working.

Ok I got the same problem. And this is the way how to examine where the problem is. You have to check that you can see the image on screen by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons (Power on both cpu and monitor), there will be a minor problem. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken. If you cannot see any icon on the screen. I would say that there are some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or dark spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.

WHY IS THE GREEEN POWER BUTTON FLASHING ON MY MONITER AND THE SCREEN THEN GOWS BLACK


When the power light is flashing the monitor is not getting a stable signal. This is hard to answer without direct troubleshooting. Check the cables first, make sure they are connected securely. If you still have problems test another monitor you know works or move monitor to a computer you know works, this will determine if the monitor is the problem or not and tell you if it is your "graphics port or adapter". If another monitor works fine, use the working cables to test the "broken" monitor. If you have an "all-in-one" computer, ignore the above steps and use a start-up repair disk. The reason this is hard to troubleshoot is there are so many things to diagnose. More than likely your "graphics card" is failing. These are some tricks to repair. You can update the driver, buy a graphic card separate from the stock port.

There are more than one inverter circuit for this model. One is prone to have poor solder connections in the transistors Q8 & Q10.
Another can be repaired by replacing 2 1uF electrolytic capacitors near the center edge of the board between the lamp sockets.
