Monitor blackening out and sudenly shuting down...
Hi, mi monitor recieved a front impact from a tennis ball but i was ok at the time, few days ago a saw some pixels that werent working right on the middle of the screen (then i thougth damm tennis ball!!) but later the bad pixels started to grow!!! and go up... they reached the top of the screen and i had a black line from the middle to the top... after a while.. the center pixels started HEALING!! they r fine now, but the "Stain" is moving now on the top of the screen...
thats 1 problem...
the other thing is that the monitor sudenly shutted down and the green light started to go on and off... and it keeps doing that.. im testing it now plugging it to my notebook to se if the problem persists.
I really apreciate any help anyone can give me.
Hello!
Sorry to hear of the Tennis Ball Masacre.
I believe your problem to be twofold in nature.
First the glass in side of the LCD screen is very fragile and the tennis ball most likely ruptured it. the streaks are most likle the liquid crystal solution leaking out. the dark streaks represent the absence of the fluid.
Secondly, the monitor shut down appears to be from the back light / inverter circuitry. Sounds like it may be time for a new display.
$40 to $60 for the inverter board and $80 or more for a new display screen, you may as well go the couple of extra dollars and get a new monitor.
Hope this puts it in perspective for you. Sorry it is so bleak!

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc. http://en.wikipedia.org/wiki/Capacitor_plague Please post back what you find.
start button >settings >control panel > Power Option > set time for monitor to sleep if inactive...if you dont want the computer to sleep go up to the hibernate tab and uncheck it. If you want the computer to stay on regardless, move all drop down menus to "never" instead of a time.
I suspect the power supply for the monitor. Try a power supply from a working monitor. If you have a used computer store nearby, take your power supply to them and try it on another monitor.
There is no need to turn off a monitor using its power switch. Monitors automatically go into standby mode when they are not receiving a signal. In standby mode they use less than one cent of electricity per day. If saving electricity is your goal, raise the temperature in your home by a degree and run the air conditioning less.
To solve the problem on my monitor i did a thorough inspection on the pcb which is fixed on the tube and i solder components which looked suspicious for dry joints.
if there are too many black spots already then that means there are lots of dead pixels on your lcd and it cannot be repaired anymore. that will continue to add more dead pixels and eventually damage the device.
One of the buttons on the front of your monitor is probably stuck. (Only one of the buttons work at a time on most monitors)
I cannot recommend taking it apart your self (have a tech do it) But take off the front, check the buttons after you take off the front, and if it still occurs unplug the buttons from the monitor. If it stops (which it should) replace or fix the controls) If it doesn't, call an exorcist (just joking) or buy a new monitor.
hi there, check the system if it is ok, if so, check your video cable, you have a video problem. try to see if there is a cold solder on video section, do some test. ty
