When I boot the PC the monitor stays in standby mode. I have changed monitors but the same problem exists. It doesn't appear to be connecting. It is a problem that has materialised. The PC and Monitor were working successfully before. The operating system is XP. The graphics card is an ATI D33053.

CHECK IN BIOS MODE ,THIS PC NOT GOES TO STANDBY SO PROBLUM IN YOUR OS .FORMATE PC NOW CHECK .

Make sure you have the cable that plugs into the back of the computer from the monitor screwed in tight. Also make sure the cable on the back of the monitor is screwed in tight and also that the power cord on the back of the monitor is pushed in all the way.

I'm almost certain you're not in standby mode. Does the computer stay on when you get the no signal message? Do you hear the fan blowing, do you hear the disk drive spinning? If not, I think your system has completely shut down. I'm thinking maybe a virus or some hardware/software conflict is stopping it from completing the boot cycle.

Try getting into the Bios or System Setup to see if the LCD Stays on and the computer stays on. Turn the computer off, then hit the power button to turn it back on. Look at the lcd screen and it will tell you what key to hit to go into the Bios or System Setup. Go into it and let the computer sit for 10 minutes or so to see if it shuts itself off.

If you are successful with the computer staying in the Bios or System Setup lets try getting into Safe Mode and see what happens. Turn the computer off and hit the power button to turn it back on and immediately start hitting the F8 key repeatedly until you see the SAFE MODE option. Select the Safe Mode option and let the system boot up. Safe mode will look different to you. The icons will be bigger and the lcd screen darker, but that's normal. If you are able to see the desktop in safe mode just try opening up MS Word and maybe let it sit for a few minutes to see if it shuts off.

If safe mode was successful, then try booting it normally. If it fails, we know we've got an issue.

It sounds like a driver conflict or software issue with the video card. Try booting to Safe Mode by hitting F8 during the boot sequence. Choose safe Mode with Networking to maintain your network connection. Safe mode loads a generic display driver and will allow you to troubleshoot any issues with your existing drivers and/or software.

when you disconnect the monitor from the PC do you see the self test appear on the screen? if you do then the monitor is working fine.
the issue is most likely that the computer's screen resolution is too high and your monitor cannot output that resolution , so it stays a blank screen or in 'sleep' mode as you described.
youd need to go into either Safe Mode when booting the system or find another monitor preferably a newer model to connect your computer to and decrease the resolution before connecting your monitor.

Hi,

If you have an extra monitor try connecting it. If it works fine, if not then there might be some issue with your video card itself.

Regards

Try tapping F8 when booting and then choose 'safe mode with networking'
if this works go to the lcd manufactures web site and look for a specific driver for your screen.

the monitor is going into power saving mode ... it can happen if it is not receiving any signal from the pc ( pc is not running or booted properly, bad video cable connection monitor to pc) or the pc is itself in suspend/standby mode.

Sounds like a bad graphics card. Try using monitor wit another computer and see if the problem still exists. This rules out the display.

try to boot on safe mode, by pressing f8 while booting then choose safe mode,

while in safe mode you can set the resolution back to its default .

Hi The problem is to do with a 680uf capacitor that tends to bulge and fails.this stops the monitor staying on when trigerd to do so,change this and happy day.
