My monitor will not come on any longer. When I press the power button, the green light comes on and message appears on the screen, "something about press 1 for digital mode". I have done everything I can think of but the monitor will not stay on. What can I do?

I don't know what you're referring to, but here is something i think it might be...
1. Power on the monitor.
2. Press and hold the MENU button for at least 15 seconds.
3. Look to see if an UNLOCK icon appears on the screen.
4. Release the MENU button and wait 5 seconds.
5. Press any button on the monitor to test.
6. Turn off the monitor if it is no longer needed.
You need a new backlight inverter board. If you dissasemble the monitor you will see a circuit board with 4 2-wire connectors connected to it. This is the board you need to replace. Typically they run from $15 to $40. Usually just easier to replace the monitor. Another idea is to reduce brightness levels on the monitor in the menu while looking at it with your flashlight. Then power off then power on the monitor and it might stay on longer.
We have a dis-assebly and repair guide posted on our web site at: www.ccl-la.com/monitor_repair.htm The problem is usually the driver transistors, our guide shows where they are and what to replace to get your monitor back running again.
It's the backlight supply tripping out from backlight failure, but the thing still stays on. I got it to act right by switching to factory presets with some fast menu action once, but the general solution is going to involve tricking the backlight into staying on; you can look at the thing in bright ambient light to see that the display is still working, but of course without a backlight it's pretty much useless.
Since $100 buys a better and more efficient monitor, just replace it; otherwise of course you can either replace the backlight (or go for one of the projector mods) or convince its drive circuit to put up with it a bit longer. I spotted a bad capacitor but swapping that out hasn't gone well yet....
I would suggest that the "Event" that caused the CB to trip has caused ya Monitor to fail.. Probably in the Power Supply, My "Pet" area... lol.. anyway Thats wat I would think. It may even have an internal "Fuse" that has "Blown"?
The circuit breaker popped due to power fluctuation or something else ? It is clearly understood that your LCD monitor suffered some component burn inside otherwise it would show 'NO SIGNAL' sort of Display if it is not connected. There is nothing to resset. Please open it up & check if there is any sign of burned component or take it to a service center if it is still under warrenty.
It totally sounds like the backlight is toasted. If that is the case you will have to replace them. Normally if the power inverter is shot, the monitor will power up briefly at least and then shut off. If you can use a flash light and see some sort of image on the screen you know that your VGA chipset works however your backlight(s) are burnt out. If not, more than likely your power supply (power inverter chipset) is broken and needs to be replaced..
