Monitor shuts off during boot. Let the machine boot full up, hit the power button, the monitor flashes windows for a split second, and goes back to power saving mode
My monitor just went to power saving mode right after I was playing CoD4. I've got an older monitor hooked up just to keep going, but, I was needing to know if this monitor is trashed, or, if there's something else I can do to fix it. It's a LG Flatron L1932TQ-BF. I'm running an BFG 8800 GT OC and have tried both analog and digital. Once the machine is up and running, I can click on the power button and windows will flash for a split second, and then it will go back to power saving mode. Any suggestions?

It is possible that the monitor is going back into "Sleep mode" meaning it is not detecting a valid signal from whatever device it is plugged into. I would try replacing the cable that is connecting the monitor to the PC or Console. As a trouble shooting step try pulling up the "Menu" on the monitor itself by pressing the "Menu" button on the front panel of the monitor, if this does come up then we can say that the LCD itself is most likely working.
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 is one of three things, One is that it's not recieving a signal, mine flash when the computer is shut down, several monitors do this now. The second is that the either the video card is in need of service, or if you don't have a video card in your machine, it is either a connection that is intermittent, check the other end of the cable, or the monitor is in need of service, there is a circuit board that gives it a boost on start up. How old is the monitor and what brand? all the info is needed to go any further, thanks, if it is 5 years old more or less it is the monitor gone bad, more than likely
No sync means no video signal to the monitor. The rest sounds like a corrupted OS. This could be from a number of reasons, including a virus. If you have NORTON or MacAfee, Your open to a lot of attacks. Get AVG free, and use Mozilla instead of IE.
The reason the fans come on full speed is the MB senses a high temp on the CPU, until the bios fan control takes over after POST. This is normal on most systems.
Sounds like you have a bad connection from your monitor to your computer. First check and make sure the connection between them is tight. Does your computer boot up and run though? If your computer is not booting up the monitor will default back to the flashing green power light
How old is the computer? Make sure that the power light comes onto the monitor when you plug it in, should be orange and then turn green when video card syncs with it when PC is turned on. If you are getting black screen when PC is powered on:
1. Bad video card
2. Bad video cable
3. Bad monitor
1Solution: Try using a different monitor attached to this same PC and see if it works. If it does, then its the monitor, its cable, or its power supply. If it doesn't work, then its the video card or the video cable coming from monitor.
while the monitor is still powered on, but with the LED flashing, unplug the monitor from the PC. press the power button, and the monitor should go off, now plug the pc back into the monitor. Turn the monitor back on and it should work.
Occasionally this will not work for me, but if I repeat it it normally works
Hope this helps - my problem is intermitant so it may be different to what u guys have
