Try pressing the "Auto" button located by the power button. If that doesn't work, I have a few questions for you.

P191w


Hello,

The Acer p191w uses the same power supply as the Viewsonic VX1962wm that your problem is a well known issues with that power supply. The filter capacitors go out and that causes the power supply to shut down within a few seconds. The monitor is easy to repair, you will just need to replace the bad capacitors on the power supply board. Here is a link to a repair guide for the Viewsonic VX1962wm and the information will be the same since the boards are the same in both units.

Before going to replace CCFL check the inverter of the CCFL. Normally the inverter get faulty. There is possibility that the winding of the high voltage transformer get shorted or its driver transistor may get faulty. check the same

The monitor powers on & a picture displays for only a second or two then the screen turns black as if it is off but the power indicator light below, indicates the power is still on.


There are a couple reasons why a monitor does this. Either the monitors back light has gone bad or some of the capacitors on the board have gone bad. If you're up to opening the monitor you can usually tell if it's the capacitors because they will be crusty white/brown stuff oozing from them. Replacement capacitors can be purchased online or at RadioShack and are inexpensive. The light kits can also be found online and are usually less than purchasing a new monitor. In either of these instances if you look closely at the monitor, while it's powered on, you will see the desktop image. Often times shining a flashlight at an angle on the screen will help you see it. If you're interested in opening the monitor let me know and I'll be happy to point your at some walk throughs for this. I hope this was somewhat helpful to you.

Acer lcd screen p191w makes a buzzing noise when turning on and the screen is very dim. then it shuts off. can this be fixed at home


Not safely and not unless you are confident and competent with electronics. I would put the dimming down to a failing display circuit, but the buzzing sounds as though a short is developing. I would take it to a tv repair shop who can advise better and maybe replace or repair the components

Acer P191W smears all objects


brianfh01, Hi, I'm louie12fix. Can't say we will be able to fix, but we can try some different things. Will P191W do same stuff if connected to different PC? Did it work (perform perfectly) one day, and then act like junk the next day? Did you check with ACER about warranty service?? Are you using this unit for business or home? Can you, or did you connect different monitor to the pc that the P191W was connected? I certainly would be trully ********** if a 4month old monitor didn't perform to specification. Did you buy it locally or online? If local, maybe the store will swap it out for you. Bye for now. Get back to me at louie12fix on fixya or lmistyrel @aim.com
