2407 screen goes black

This sounds like the inverter which powers the display fluorescent has or is failed/failing. If you take a torch to the blacked out display can you see the image faintly? If so the unit needs repairing.

Any error message about inputs? Maybe that clicking sound happens when iit connects to the selected input, but nothing is connected. Can you scroll thru all the inputs? If so, turn on any devices connected to the JVC and scroll thru each input to find the one you're looking for.

It sounds that the main digital board to this TV is faulty. Contact any service technician.

The capacitors for the power source are failing. This causes a short burst of power to get to the lamps, but then they cannot hold a charge to continuously power the lamps. You will have to replace the monitor. I suggest checking your warranty status and replacing the monitor.

mine did that.

its the main power board inside

I found this on the Internet...

"Press the "Input" button on your LCD monitor's front panel repeatedly at three- or four-second intervals until your monitor wakes up. If your monitor is set to an incorrect input mode, it won't receive a video signal. After you reset the monitor to the proper input mode, it will receive the signal and wake up automatically."

I have provided a Link with more info for you!

The problem could be the CCFL lamp, especially if the image has a pink hue.

I have the same problem. The next stage is that the picture won't come on at all and the blue light will constantly blink. I think the light source is bad. Noit sure though.

The LCD screen may be burned out. There's whats called an invertor board and there is an electronic ribbon strip on the LCD itself. If you look very carefully you can probably see a faint image on the screen. The LCD screen will need replacing. Before doing anything with this monitor, try it on another computer first and if you can try another monitor on your computer. Other than that, there really is nothing you can do but replace the monitor.
