I have a 19' Proview LCD display. Recently it startet turning off by itself after working for 4-5 sec.We connected it to another pc and the display acted the same way - it worked for 4-5 sec, then it turns off. We have to press the on/off buton to turn it on, works for 4-5 sec and then goes black again.
I have a proview PL926WBI lcd monitor when i turn it on the background is a little red tint to it wich lightens up after about a minute or so then the screen goes black. I manually turn it back on and does the same thing . over and over. I have tried different cables and switched computers it still does the same thing .
You need to contact Proview. It is a problem with the monitor. I had the same problem and I was lucky. The warranity was going to run out in 15 days. They sent me a return number "I had to pay shipping and insurance" and they sent me a replacement. The replacement had a problem with the screen. It looked like it had been shot by a bb gun. Proview is refusing to replace. Hope you have better luck. Here is their contact info. By Phone: Service Hotline: (800) 776-8439 Office Hours: 8AM to 6PM Pacific Time

Any monitor will work with any computer provided the correct graphics card driver is installed. When you install Vista and you do not install the graphics driver, Windows will default to Generic VGA driver and you will not get the best resolution that the monitor can display.
If you have a capacitor tester.. i'll be much better at least you would know which caps that actually failing..
I would replace all the caps if you dont have the tester.. and while your at it. try to resolder connections and some parts like transistor etc.. maybe they have "cold solder"
This may be caused by the death of a display driver circuit and these might be integrated with the display itself.
The pixels on the screen are controlled by an X-Y matrix and the matrix may have signal lines that are somewhat shared for different screen positions.
I doubt that this is DIY project and the failure can only be located by an equipped and trained tech.
This is an inverter board problem. The inverter supplies the high voltage and frequency to run the CCFL backlights. The board has a sensing circuit to shut down the output if too much current is going to the backlights or it will shut down if the transistors overheat. I have replaced transistors on some boards with higher rated transistors and they have worked great for years. Sometimes it is just a cold solder joint on the inverter board. Replacement boards are expensive but not too difficult to replace. Repair requires some ability with electronic boards and should not be attempted if you do not posess the skill. You could end up damging other parts that cost more.
I bought Same Monitor Dec. '06 and Jus last week It faded to black and
then now doesn't power on. my protection plan sent me a new one that
powered on for like 20 secs. So now I have another one coming. I also
knows its not my PC cuz I'm using a monitor right now. I think Proview
and Circuit City Sucks
