Question mark on lcd - DCP Brother Office Equipment & Supplies

Man thats horrible

did this start happening when it was first hung on the wall?

Connect your LCD screen to a different computer and check if the dark tide mark still present. If you still see the dark tide mark, your LCD screen is malfunctioning. The pixel can be dead. Contact your vendor for warranty.

LCD monitors do not need degaussing. They operate in a completely way to CRT monitors.
Tiny black marks are most likely dead pixels, if the black marks are large then the LCD screen may be damaged (cracked glass).
This type of damage cannot be repaired simply, the screen needs to be replaced.
I suggest you put your money towards a new LCD monitor.

I would use a permanent marker to mark the first set of screws that hold the perimeter, and put these in a ziplock bag and mark perimeter. You will be actually marking the slot these screws are in, and the bag should also be same marked color. The center screws with another color, screws in another zip lock bag and mark center screws. You may also ad the count to the ziplock bag. Do the same for the A/V connections etc and internal screws...etc. This is tedious but will produce a happy reassemble.

The outer covering on LCD TV's has a special scratch resistant coating on it. So, the LCD panel can get broken and you will see no marks on the screen.

If its just dirty marks use a solution of 50% deionised water and 50% isopropyl alcohol. Use a lint free cloth and it should lift the marks. Any household polish etc may react with the LCD surface and burn it. If you cant get hold of isopopyl go for branded cleaning kits for LCD TV screens. You'll get these in most electrical stores.

Hello,
Put camera in Auto mode (green mark) on Jog dial at top and there is control / navigate switch near LCD, check upper button, it has Flash sign / mark on it. Press this button and observe Flash mark(yellow) in LCD.
Flash is ready now and take picture.
Need further help, let me know.

If it is on the lens itself , you can simply wipe it off.

If this mark shows even when there is no signal in the unit and you wiped of the lens , you might be looking at a burnt LCD

LCD is damaged and needs to be replaced. The cost of replacing is less than buying a new camera. If they charge more than 50 of the cost buy a new camera.
