Question about Sylvania L181 18.1" Flat Panel LCD Monitor

Sylvania L181 stays white in standby

I saw an earlier post on this same problem, but I don't think the posted solution addressed the issue. I have a Sylvania L181. In the Windows XP Power options, I have asked for the monitor to be turned off after 5 minutes of inactivity. When the 5 minutes passes (I've tried varying periods of inactivity), the image from the computer goes away but the LCD turns completely white. I expect the LCD to go into a standby mode and for the screen to be black. The L181 seems to be doing the opposite - staying completely lit (bright white). It's almost like the LCD is doubling as a light bulb! The solution posted for a similar issue on this message board explained why the On/Off button blinks twice to indicate the LCD is in a "soft" off mode. This is fine, but it still does not explain why the LCD remains lit when it should be in standby (off). Thanks for any help you can provide!

I have an Emachines computer with Windows Ultimate Vista on it. While I am using my computer it wi8ll go white and it won't come back on, I push the Windows butten so I can get back on internet.


Windows Vista is the worst OS ever brought out by Microsoft. You need to upgrade to Windows 7 or downgrade to Windows XP. As long as you keep using Vista you will always have problems.

When I power off my LCD monitor, the screen goes all white, but once I turn the monitor back on it goes right back to displaying whatever it should on the screen. Or when I shutdown the computer it also...

If this has happened to two monitors on the same computer, then i dont think the problem is with monitors, i think the problem is with the graphics on the computer, i suggest uninstalling the driver for the graphics card in device manager and then restart the pc to see if that makes any difference. The divice manager in in the properties of my computer icon, just right click and choose properties, then device manager.

My monitor will not shut down - screen stays white

You got a short circuit in one transistor located at the inverter area. The transistor is acting like a conductor and not shutting down the power to the back light inverter. If you are a technician and want to fix it, look for short circuits in transistors.

Good luck.

Power supply dead


i think u saw the information pasted on the back side of monitor...
dead means that something is wrong inside...
initially, you have to check the power cable and availability of mains in the socket..
if all are fine then we will go inside..

after removing the cover carefully, check the mains fuse that is near the power cable socket where the power plug inserts...
if fuse is fine then check the mains capacitor and then further....
Maybe the problem pin points here and u solve the issue..


hopefully, it will fix the issue so rate it ...

Monitor lives its own life ;) Turnes off and on in random moments

It sounds like there's a problem in the power supply or inverter section and it's just teetering on the edge of failure. The disruption of the signal is apparently just enough to kick it over the cliff until it's reset. Sooner or later, it'll need some help, like connections, capacitors, output transistors, capacitors, transformers. Those are the most common failures in these. I think you'll see it get worse

Monitor goes to white at cpu shutdown

The problem is in the "soft switch" technology: On some of Sylvania's newer monitors they have incorporated what is called "soft switch" technology. This allows your ATX power supplied computer to turn your monitor on and off using it?s software controls. Therefore, your monitor?s light will always stay on blinking even when your computer is off. The monitor in normal operation consumes about 80W of power; in the "OFF" state it will be reduced below 8W. The "OFF" mode of the monitor can be controlled by the PC input signal or by pushing the soft-power button to disable the PC signal control for manually turning off the monitor screen. Thus, when the monitor is in soft-power "OFF" mode it still consumes a very small amount of power. For the purpose of making it noticeable to the user that the monitor is in soft-power "OFF" mode, we designed the power indicator to provide for a slow blinking signal (every 2 seconds). If you need to totally turn off the power, then the power cord would have to be unplugged. The same is true of the PC itself, but the PC does not provide for notification while in "OFF" mode. Your monitor looks like it may be in need of repair, contact info: PTI Technologies Inc. 7372 Doig Dr. Garden Grove, Ca 92841 Phone: 714-799-3899 Fax: 714-379-6290 Hours: Mon - Fri 8:00am to 6:00pm PST
