That could be normal operation if it is not connected. Does it do the same when connected? If so, try another monitor. Does the computer power on normally otherwise?

My pc is showing a white screen when iys on


Is it an LCD monitor ?
When an LCD screen has turned completely white, there are three normal causes: the screen is defective, the video cable is not connected correctly, or the graphics card on the motherboard of the computer is faulty. You will need to troubleshoot these possibilities to determine which problem you have. If you are not experienced in working on computer equipment, you should not attempt to disassemble your LCD screen because you could easily damage it. Seek professional assistance unless you have experience working on computer hardware.

Disconnect the white LCD screen from the computer by unscrewing the blue monitor cable. Connect the working LCD screen to your computer by attaching its blue monitor cable to the same slot. If your computer display does not show on the functioning LCD screen, try rebooting your computer. If it still does not display, the problem is with your computer's graphic card on the motherboard. Seek professional repair assistance. If your computer display shows normally on the working LCD screen, proceed to Step 2. Unplug the LCD monitor with the white screen. Disassemble the rear panel of the monitor with the small screwdriver. Carefully separate the screws into piles so that you can keep track of how to reassemble the monitor. Locate the internal video cable, a gray cable with a plug on the end that connects to the main components of the screen. See Below for the References section for photos of the video cable for assistance. http://www.laptoprepair101.com/laptop/2008/04/13/laptop-lcd-screen-turned-white/ Unplug the cable, checking for any debris or blockage. Reconnect the cable firmly. Reassemble the LCD screen. Plug it in and connect it to your computer. If the screen is still white, you have a defective LCD screen. You will need to replace it or take it to a professional repair service for assistance. Hope this helps.

My computer monitor screen display turns from white to yellow due to my daughter pressing the different buttons on the keyboard.

Kids always do this.

But let us see, does your monitor turn on and off correctly? And also please describe the problem competently to understand well and help you? Like which key pressing will change the color etc.,

Just in the mean time do check the cable connected at the back of the PC

Check the pins on the end of your vga cable from the monitor to make sure that the pins aren't bent.

If they are not bent then it could be a problem with the monitor itself. Try resetting the defaults on the monitor itself and see if the problem goes away if it does then your set.

If the problem still exists then try a different known good working monitor on the computer. If you still get the same problem then its a problem with the video card. If the problem goes away then you know its a problem with the monitor and would need to be replaced.

My Sony Moniter suddenly turned to a bright yellow


If the display looks normal other than being yellow, it's missing blue.

This may be because of a bad cable. Sometimes the wires inside break from flexing. Try wiggling the cable (as mikeslab suggested) at the end where it connects to the computer. Also check the plug for bent pins.

It's more likely the monitor has lost blue due to solder connections to the blue output transistor or transistor failure, or that the picture tube itself has gone bad and the blue gun has quit. Tube failure is pretty rare. I've seen many cases of bad connections and transistors, though.

If the cable and plug aren't the cause, you can have a service shop check the monitor and give a repair estimate. But if this is a 17- or 19-inch monitor, you might just want to replace it. New LCD's are $150 or less. To repair yours would be around half that cost already, possibly more depending on labor and parts costs.
