I purchased a vison 19" monitor about a year ago model number v193WDB with DVI input and I am having problems with it. It starts up fine and works for a while then it goes dark. If I restart my computer it will work again for a few minutes then go dark again. It happens regularly and its very frustrating. Unfortunately Frys warranty is no longer valid and naturally right after the warranty expires the unit starts acting up. Any ideas as to what might cause this and how I can fix it or have it fixed? Please assist asap with info or someone who can help me. Regards, Dave

Welcome to the world of disposable LCD monitors. I got one of these at Fry's, but have had no problem except that it won't accept HDMI input from my DVR.
Check the screen after it blacks using a flashlight to see if you can see the actual information displayed. The LCD is backlit with CCFL - cold cathode fluorescent light - tubes located at the sides or the top/bottom. They can go bad, and over draw the inverter, or the inverter, which converts ~12vdc to ~10,000Vac, can have capacitors which are low quality and are drying out, changing their value.
So, open the display up by un-snapping the plastic cover, removing the screws holding the metal support to the backside of the display, and then the back cover. Most have snap-together bezels that can be separated by using a thumbnail between the two pieces. You should then be able to inspect the power supply, inverter, and display logic board. Look for capacitors that have drooled or have their tops puffed up. Those are signs of failure.
Let me know what you find.
