If you are going to DIY repair, please look at Viewsonic photo albums and read about bad caps so you will know what to look for and know what bad caps look like.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Volume window stuck on screen


My HP w2408 monitor. I just fixed this issue about 5 mins ago after getting tierd of whacking the buttons with anything handy. There are 2 slots on the underside of the monitor, in between the black frame and silver outer frame. Stick a flat screw driver and use a motion as if to literally pull the black frame away from the monitor. Use caution and dont stick the screw driver too far in. You will hear it pop. Do the same to the other side. There are multiple tabs arond the frame including one in the bottom center. Keep pulling on the free ends of the frame till all the tabs come off. Now you will see the buttom assembly, disconnect the small white connector from the montior. If you dont care for the buttons, which if you have a w2408 or any such model you will never use (auto detects input and auto adjusts) then just pop the frame back on. If you want to go further remove the 2 screws on the button assembly pull down on the silver frame to remove the button assembly. I did not go further then this but i read somewhere that if you wash the assembly in some liquid it will work again. I am guessing some good acohol from walgreens will do. For me I am just glad the message when away.

Keep fixing and keep sharing! Corporations that sell to the masses will show respect only when the masses unite.

My dell monitor will only turn on for a few seconds then it goes black. it doesnt turn of it just goes black and I can keep doing it and it will keep going black.


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 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.

Hello,

It is the picture picture board on your monitor that is malfunctioning, since the power led or button is on, but black screen, it means the picture board of your monitor has developed fault.

Gateway FPD1750 monitor's keep go black screen, no picture at al


tgordon60, If you know how those NEW "CURLIE-Q" energy efficient CFL light bulbs produce WHITE LIGHT, then you will know what makes an LCD display panel produce all the pretty colors and the WHITE BACKGROUND of the FIXYA web page!!! Only difference is that your "cold-cathode-fluorescent-lamps" are thinner and straight, and hung on rear of LCD glass panel and have a DC to AC electronic ballast called an "INVERTER" circuit to produce 600 to 1000vac to light them up. Get to my FIXYA profile and read my responses to other BLACK screen lcd owners to learn about all your options for repair. Follow any of the links to other web pages you find there. Your monitor not any different than ACER, DELL, VIEWSONIC, BENQ, SONY, AOC!!!!! 12fixlouie aka louie12fix

Flat Screen monitor keeps going black


Make sure that the power cord is plugged in firmly and isn't being pulled tightly by anything. Also, make sure anything isn't toughing the monitor's power button. Also, try plugging the monitor into a new power outlet.
