My AOC screen goes black after about a few seconds after booting.


Hello,

The picture board on your monitor is bad, since it goes off after few seconds and the power led or button is on, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer or service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

DELL 2208WFP LCD-Comes on normally, but almost immediately goes dark You can see something on the screen if you look closely. Turn it off and back on you see it then dark. any help?


Hello,

I believe the power led button is still on while the screen goes dark, if yes, it means the picture board of your monitor is bad that is why it appears for a second and goes dark after that

Since the power led button is on, It means the picture board on your monitor is faulty that is why it appears for a second and goes dark.

The best thing for you to do now is to take the monitor to a local repairer or any service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself in other to complicate issues.

Take care.

Monitor turns on then goes dark


Either the power supply board is failing and needs repair or a bad bulb in the screen is causing it.
You would have to open it up to get a better idea.

Here's some info:
MAKE SURE ALL POWER is DISCONNECTED For at least 5 minutes PRIOR TO WORKING ON inverters.
If your picture wasn't pinkish or dark at the top or bottom when it was working, then it may be the inverter has gone bad. Inverters are like light bulbs and have life expectancies on the capacitors.
If your picture was pinkish or dark at the top or bottom when it was working then you may have 1 or more of the bulbs failing.
You can check for pinkish if your screen flashes.
What you do is when you have it open to the point of getting to the wires that hook to the back of the lcd screen is to disconnect only the wide ribbon that goes from the video board to the back of the screen. Then start it and check the screen flash color.


These come apart a little different than most. The front trim comes off with the screen. So essentially you are removing the back case first:
Once the four screws are out of the rear corners there are snap tabs that need to be released between the silver trim and the back black plastic (three top and bottom and two on left and right.)
You can use a thin knife blade to help release them as you separate the silver from the back plastic Black part has to be bent outwards to release these tabs.
Then entire guts will come out with the screen ., then the inverter is under the center area under the metal cover.
Shout if you need more info.
If you email me a good picture of the inverter in the area of the larger yellow square component and one from underneath , behind the two small yellow square components, I may be able to get a better idea if it is the inverter from a visual.

I turn it on and it comes on for a second then the goes black


You need to open it up and inspect the capacitors (look for bulging top/seal), burnt inverter transformers, resistors, etc. in the power supply/Inverter board first, post back what you find so we can guide you further. See example of failed Viewsonic monitors: http://s807.photobucket.com/home/budm/allalbums

Hitachi CML174SXW B randomly goes black


Have you noticed if the monitor gets hot before it turns off?

Please, don't open a monitor and try to repair it yourself. It can be very dangerous and it's not worth getting injured.

Have a viewsonic va720 screen on and picture on and back off just as quick


One of the backlight converters might be failing. Check the fuses on the converter, or ask a technician to do it for you. Good luck
