Monitor just stopped working, screen is white.

Has worked before and stopped working or never worked before?
If not worked before ensure your output ie HDMI has the correct converter cable or adapter to connect to monitor AVI or VGA port ie blue or white socket. also check the cable is ok try changing cables, or using a different port. test the monitor with a pc to ensure the monitor port is working test the ps4 with another device to ensure the output from the ps4 is also working.

I hope this was helpful.

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

Check the system compactability.

To check if the graphics chip is OK connect an external monitor to the video port on your laptop, power up the monitor first then boot up your laptop, if Windows appears on this monitor then the graphics chip on the motherboard is OK. The white screen indicates the inverter that supplies high voltage to the CCFL lamp is also OK.
The fault is either a loose video connector that connects the video cable to the motherboard or the video ribbon cable is faulty. Try reseating the connector the video connector will either under the keyboard or under the plastic cover between the LCD screen and the keyboard.

This is a high voltage horizontal output problem. Could just be a loose connection or an intermitant component failure. If you can get into it, check for any loose connections. Sometimes this can also be caused by a large accumulation of dust. Make sure you unplug it before opening it up.

Suggest connecting monitor to another computer and confirm defect. If problems reoccurs and cables are confirmed OK replace.

That looks like a malfunctioned LCD display or the connection between main circuit board and display is bad, you have to open the monitor and check connections but first be sure that
1. Your VGA card works ok 2. The VGA Cable connectors are ok.

there are many reason why a monitor suddenly turned off then back to work again , over use may over heat that cause the soled parts on the printed board of your CRT go loosen , try to re sold it, sometimes your PC might stop viewing so the monitor automatically shot off stby mode , loose connection due to basted parts , capacitors,power regulators,resistors , even the cables also might be.

Hi! For dell machines when u unplug the video cable/VGA from the tower while the system is on it will show monitor self test.If you are seeing a black box moving around the screen it means that monitor is ok.Check connection between monitor and tower.Make sure cables are securely plugged in.Check if the tower is ok. There is a possibility that your monitor is ok but the tower is not.check the power button (whats the color) if amber/orange, this means there is something wrong the the tower. If its blue or white it means its ok.Also check if you are going to hear one beep, it means system is booting up properly. If tower is ok and you are using a expansion video card then try to use internal one, normally its the vga port above the usbs.If you are going to use onboard video card make sure you enable it first in bios.If all things fail, contact your manufacturer, if the system is under warranty then they will send a tech to check the machine.hope this helps...

the -ve ground voltage decreased when u saw the screen goes white.if it flash too much then may be the front phosphorus coating burn due to excess whiteness suddenly. if that is ok then check the the G1 voltage , they are in excess, follow the track and replace the components after checking. also check the heater voltage and screen voltage (G2) ( do not touch the G2 voltage without insulation. they must be between 500-1000 volts. if they are disappears then check the EHT transformer. if the problem still prisist then inform me, i will guide u step by step.
