Probably failure in the LCD controller IC in the lcd controller board. that no signal was sent out to the lcd driver IC thus you could only see white display. A replacement of LCD panel is the best solution. I suggest to bring the unit to an authorized service center to properly diagnose & fix the problem. regards

This monitor gives me a complete blank white screen when plugged in even after checking with multiple computers what part would need fixing or replacing for it to function properly?


check first any broken ribbon wire going to lcd panel or broken screen display. if those are good, the cause of white screen would be bad lcd controller board.

Monitor is blank


HI there,

Problem : no power
Action : * Make sure power button or switch is ON.
* Make sure A/C power cord is securely connected to the LCD display.
* :Plug another electrical device (like radio) into the power outlet to verify that the outlet is supplying proper voltage.

Problem : Power is ON but no screen image.
Action : * Make sure the video cable supplied with the LCD display is tightly secured to the video output port on the back of the computer. If the other end of the video cable is not attached permanently to the LCD display, tightly secure it to the LCD display.
* Adjust brightness and contrast.
* If you are using an Macintosh older than G3, you need a Machintosh adapter.

Hope this helps.
Have a goo day.

Monitor flashes on then goes black.


I think you have the display shut off. the button on the bottom left will shut screen off. It will come on for a few seconds if you touch the screen, but will shut off again. just push the display button again and it should stay on.

BRAND NEW BUT NO DISPLAY


I also had the white screen / blank screen problem on my Inno today.  I powered the unit off, removed it from the home cradle, and then popped out the battery for about 15 seconds and put it back in.  This fixed the problem.

Blank white display on Nokia 3230


This is a major fault, screen gets blank white because of some problem in its display panel which is right behind the LCD screen. Rush to the nearest Nokia care centre and explain the problem to them.After the repair if you experience this problem again and your phone is within the warranty period you can demand a brand new box piece!
