Purchased a monitor at a PC Fair, but at boot up, screen goes straght to an all over yellow screen.Does not even show post instructions on black background. PC appears to carry on booting up OK, but screens stays all yellow even after waiting for 5 minutes or so. Is ther some thing I can do to alter picture resolution ( someone told me to try altering horizontal and vertical kHz and Hz ), but do not want to try this without confirmation. I am using VGA connection (HD15), but the monitor also has a DVI-I conection (not tried ). At self test with PC connection disconnected, I get all color bars showing correctly, but after connecting PC lead, I get the No signal received message. Any help would be greatly appreciated . This seems to be a great monitor if I can get it working. My OS is Windows XP Home. Many Regards, Dave

you disconnect the monitor from PC
& see: it will show no signal or check signal cable. that means the monitor is OK problem is in PC. may be you PC is not booting properly. if monitor does not come on there may be fault in the main board of your monitor.
The picture board on your monitor is faulty or bad, since it goes
black after booting, it means the
board of your monitor has developed fault.
The best thing for you
do now is to take the monitor to a local repairer within your vicinity
to help with the replacement of the picture board
because the fault is not something you can fix yourself. in order not to

If you look at the monitor there will be an led light on the front that is always orange or yellow when the computer is off but still connected to the monitor. This led will turn green when the computer boots up, sometimes even showing a "no signal" display before boot. If you see the 'command line' text during the boot process (video info, BIOS version, POST text, etc) then the monitor is being recognized by the computer. If that text goes away and the led goes back to orange then it is a driver or operating system problem. Pressing whatever key is prompted at the lower left of the display, if you have a display, like F1, F2, F10, Delete or whatever will get you to the setup program and all is good with the display/computer connection and a green light will stay on. If you never get that green led light then either the video card is bad or not seated properly
A monitor display showing "No Data" indicates that either the PC is not sending any usable video signal or the monitor is not capable of displaying the incoming video signal. To determine which is at fault, you would need either a known good second monitor or a known good second PC.
Additionally, it is also possible that neither is at fault and that you simply need to lower down the Screen Resolution and/or the Screen Refresh Rate of the computer's display properties to match the limitation/capability of the monitor. A method of verifying if this is the case is to start the PC in "Safe Mode" by pressing F8 after POST before Windows boot.
Alternately, there are some instances that it is the video cable that is the issue. To verify, you can try wiggling the cable to the connector end that goes to the PC's Video output.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
