Re: image go off

Hi this is the way how to examine what's wrong with your LCD monitors. Power on both CPU and monitor. After they shut down on their own, you check that you can see the image on the 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 or any image, there will be a minor problem. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken and it is easily replaced. If you cannot see anything on the screen, there'll be 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 burn 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.

Re: image go off

Sounds like the backlight is failing. If it is still under warranty, have the manufacturer fix it.

There are two possibilities, one is bad caps in the power supply, number two is shorted out transistors (P/N c5706/5707) in the inverter circuits. Please open it up and report back what you see so we can guide you further, see example fo failed monitors due to bad caps, lamps, etc:

The monitor comes on and then goes black.

Sounds like your LCD panel lamps are shutting down, this could be either due bad tubes, or more likely lamp driver power supply is faulty.

Good picture for 30 seconds then screen goes black with a faint ghost of the image

the 12V is for speakers.. the 245bw takes regular 120V AC (same cord as your computer)

the buzzing is annoying, though. i don't know if it's a "feature" or just a side effect.. ie, if i could take the case off and poke around, i would. 4 times out of 5 it's some dumb piece of tin reverberating from a transformer or something..

Monitor goes off and on

Yes your backlight is going bad! This is common with an LCD monitor! There are no guarantees with these new items! Sorry I hope that this helps! When a backlight goes bad it will generate enough light to display an image, but it will not hold that charge for very long, it varies based on the manufacturer who sells the Montior!

Monitor goes black

Sorry to have to tell you this, but this is common in LCD monitors. The reason that it is going black when it boots is for one of two reasons. You either have a bad power supply that powers your LCD or your LCD's backlight is blown. These can be repaired or you can purchase a new one. But if it goes black 9 times out of 10 is because the backlight is bad. These can be repaired!

Image go off

I have had the same problem. I've just managed to get the monitor working again by VERY QUICKLY navigating through the monitor setup menu to the 'factory reset' option and hitting reset before the screen had a chance to blink off.

The problem I had is that the monitor suddenly goes black, but will come on for five seconds if I switch it off and on with the power button.

In that five seconds, I had to...
>Hit the menu button
>then hit the '+; button once
>then hit the menu button again
>then hit the '-' button
>then hit the menu button one last time

The above brings up the menu, scrolls up off the top of the list to the last item on the list (Factory Reset), selects Factory Reset, selects 'All settings' and resets the monitor.

I don't know if this is a permanent fix, but it just worked for me and mine has been doing this intermittently for the last week.

Give it a try, it's frustrating and will take a few tries, but it can't hurt.
