Re: Monitor hit with a Headphone
The black spot can stop or keep spreading, but it will never disappear or reduce in size. This is caused from a leak of liquid between layers inside the lcd panel.
Nothing to do apart changing lcd panel. Bring monitor to nearest service and check if it is worth being repaired (changing screen panel).

Some monitors change colour if there is damage, internally, within the signal cable. Try another cable if you have one.
Alternatively, it might be that the monitor is near an extremely strong magnetic source, such as big loudspeakers?
I couldn't find any fix on this monitor so I had to go it alone.......
My VG500b monitor would power on then the power light would blink off. there was no display at all but I could see the LCD panel change in brightness just a small bit during the power on and then power off. I found that there was a bad capacitor on the inverter board. I replaced the 47uF 25v capacitor with a 47uF 35v capacitor. (The 25v would be okay but I always replace a failed capcitor with a higher voltage rating) This capacitor is the shorter form in order to fit under the shield. You can use a taller capaitor but you will have to lay it down, as in bend the leads down and lay it on it's side in order to fit under the sheld when you put it back together. VG500b fired right up and is going strong once again. Hope this helps someone.
This ones a little tricky. Hope you have strong fingers. Start by
removing the base. There are 3 screws. First pull the base plate off.
Then remove 2 screws. Next remove the little rubber insert in the center
of the base bracket. You will need a long phillips to get to the 3rd
screw. Slide out the base bracket. Flip the panel over and stare at the
lcd with the buttons side on the top. Grab a small flat head screw
driver. Look at an angle in each of the corners between the inner black
lcd trim and the silver outside trim. There is a ****. Shove the
flathead in there and pry outward toward the silver trim while lifting
on the black inner trim vertically. The trick is to flex the black trim
toward the silver and then pull up. There are 6 plastic snaps on the top
and bottom, and 4 snaps on the left and right. If you've taken laptop
screens apart, you'll feel the similarity.
Sounds like a problem with the video board of the monitor. I would contact Acer, since it less than 3 yrs old, tell them the problem that you are having get an RMA number and they will fix it for free. You only have to pay for shipping it back. Hope this helps.
some time we can see that of problem as screen convert in to voilat and green colour. it is called colour fade. assambaling parts is lose of bord and other. it can be correct by soilding by expert tech. it is more seen in old crt monitor. thanks
The monitor needs to be replaced. I had an LG LCD that did this luckily it was still under warranty. Contact the maker and have your receipt handy. Otherwise buy a new monitor. Monitors tend to be replacement only
This is a common problem when LCDs are subjected to strong shock. Your internal circuits are damaged The panel itself may not be cracked but there is internal damage. I know of no cure or repair possible other than to replace the panel assembly.
