Turning itself off

There is little info on your problem but I think you mean the screen went black while downloading a film. Normally computer monitors turn themselves off (dormant) to save energy and the life of the monitor's screen if not used for 10 or 30 minutes, depending on the settings, but the download just keeps going. Mine is set to 10 minutes. All you have to do is disturb the Mouse and see if the monitor screen switches itself on. There is another power saving option, and that is the Computer itself. If the computer is not used for one hour, it too goes dormant, but can also be set to switch itself completely off after the download is completed. However, if a computer is left on for over an hour, it can switch itself off to save energy and the computer's own wear and tear. It all depends on the computer hardware and the settings. If it is hardware controlled, then it may or may not switch itself off but it still goes dormant. Or it can be set to whatever you wish it to do, stay on all the time, go dormant after a set time or switch off if there is no prolonged activity.

all PCs new out of the box,. go to sleep
by law here (usa energy star laws)
2004 monitor
99% are all dead now, due top CCFL back lamp tubes dead
they all do that now. even intermittant for the same reasons
EOL on CCFL, end of life , all.
used 10 hours a day for 5 years and bingo EOL , happens, all.

disable a screen saver,problem will be solved.

What has happened is part of your back lighting circuitry has gone out. Yes it is repairable but can cost most of what a replacement monitor will cost these days. Check that out before spending the money. If the problem is only in the back lighting circuit then expect to spend about $100 for a replacement board.

LCD monitors lifespan depends on the quality. Normal use and you should get 2-3 years of reliable service minimum. The display itself is good for about 4000 or so hours of use or more. The problems that show up are always (well 99.99% of the time) are back lighting problems like you have experienced. You should turn it off by the switch when not using it as every hour it runs the screen save is an hour of usable life. Heat is not good for it so if your computer gets the dust cleaned out to keep it cool do the monitor at the same time. Once a year at least more if you smoke use gas heat and have pets.

Tube monitors have a much longer life but you have the size weight and poorer display to go with them. If you have to go back to a tube monitor don't go back to your 14 ask around and you should be able to get a 17 or 19 crt for free. Or expect to pay no more than $10-20 for one.

I was thinking about your problem, I just had a similar issue and the problem is that the inverter or the power supply with an embedded inverter had gone bad.

The reason it goes black is because the inverter fails to provide power to the LCD Display.

The only way to fix this is to open up the FPD:

*note these are instructions for the most popular FPD 1730*

1.there should be four screws on the back --> plus two large screws that hold the FPD stand and the Monitor together.

2.Open the back by pulling the cover off
Remove 7 screws holding the frame and the power button for the LCD

3.Remove two screws through holding a silver cover and remove cables.(pinkwhite) (blackwhite)
Please note where they belong before removal**

4.On the edges left and right are two screws 4 total ---> remove and remove LCD off of frame**becareful because the backlight Damaging can cause severe damage to your LCD panel.

5.Choose your model
Your FPD has 3 boards (power, inverter(backlights) Logic Video)
replace the inverter with well known good one

Your FPD has 2 boards(Power with inverter on edges, Logic Video)
replace the power board with a well known good one

6.Then do steps 1-5 in reverse order(putting your FPD back together.

I hope this is significant help

Okay it is definetely the Computer. If lines like that occur it looks like a corrupt system file. I wish i could help you further but i specialize more on FPD problems.

If you have software that changes your boot up picture, it might have made the image you are describing. Thats the only thing i can think of.
Theres software such as WindowsBlinds(just and example) that do these kind of effects.

I hope this helps you get closer to your solution.

it will appear because you did not shut down your computer properly,try to consult to computer technician so they can fixed your computer,its not the monitor its the cpu.

problem of smps some time it happen the power supply con't give the complet supply.
if still problem then replace RAM
or replace the display card.

This just happened to me last night.  My web research indicates that the monitor is bad...others have had the exact same problem.
