Proview Pl926wbi I have a 19' Proview LCD display. Recently it started 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 button to turn it on, works for 4-5 sec and then goes black again. Is there A fix?

Re: Proview Pl926wbi

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.

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.

I would look on the power supply board and check for any capacitors that are bulged or popped. They look like little barrels with a cross or 3 line star on the top. This is the vent and it should split before the capacitor pops like a firecracker or blows its top off like a bottle of shaken champagne. I bet you have 8 bulged or popped caps on the P/S and they can be replaced at about .30 cents a piece and a soldering iron. Just make sure you get the right farrad ratings, like 470 micro farrad and get them rated to 105c for heat resistance. Most are 25V but you can use the more common 35V safely. If you are going to toss the monitor in the trash, do yourself a favor and at least spend 30 minnutes looking into these. It may save your monitor. If the lamps even light for a few seconds, its not the lamps. If the inverter is bad, you would get no light. the starting of the lamps takes lots of voltage, keeping them going is about 1/4 of the start voltage so if they start, the inverter is doing its job.

My proview monitor stays on for 10 sec then goes black. but i can faintly see my page.

This indicates an inverter board failure, caused by bad capacitors that sometimes bulge at the top showing that they are open, an attempt can be made to repair or replace the board.

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.
