Question about ViewSonic VA1912WB 19" WideScreen Monitor

Open Question

Built in monitor speakers "buzz"

I have built in speakers in my view sonic va1912wb monitor. i currently do not use them, in favor of a better option for sound.

on occasion it would seem like.. bright, or certain color combination on my screen causes them to BUZZ. usually while playing a game, i don't see(hear?) a problem. mostly happens while browsing the web. however, im playing WoW and the zone i am in has a LOT of white snow. and the only way to get the buzzing to stop is to look up at the dark gray sky. the sound resembles high powered speakers that are turned up all the way (to 11 hehe) with no signal being sent to them, just the power it would need in case some signal were to come... i hope that makes sense... because it is terribly annoying. the only thing i havent tried is actually opening up the damn thing and cutting the wires or taking the built in speakers out. the speakrs are muted at the moment, and i have tried running signal to them to maybe..."give them something to do" but to no avail.

SOURCE: memory recall

From the Users Manual for this monitor: "Memory Recall returns the adjustments back to factory settings if the display is operating in a factory Preset Timing Mode listed in the Specifications of this manual. - Exception: This control does not affect changes made with the User Color control, Language Select or Power Lock setting." When the monitor is asking "Memory Recall OK?" it either wants to initiate a settings Recall, or it's asking if the Recall was successful. In either case, the "Memory Recall OK?" message is supposed to go away when you push either button 1 or button 2. If it does this when you are adjusting settings then it's likely just doing what you told it to, even if you don't realize you told it to do that. It's also possible for one of the settings buttons to be stuck down and this is causing it to try and change the Recall settings. Push each of the buttons on the monitor and pay attention to what each one feels like as you push on it. If one of them feels different from the others, it's likely stuck. Tapping lightly on the settings buttons or on the panel beside them will usually free up a stuck button. If a button is stuck and won't loosen up by tapping beside it, you might need to pry up on the edges of the button VERY gently with the sharp tip of a pointy kitchen knife. If it's doing this when you did not touch any of the settings buttons at all, then this is likely being caused by a dendrite whisker or faulty circuit trace inside the monitor and you'll need to take the monitor to a service technician for repair. But remember to contact Viewsonic first and go to whatever Service Center that they advise, since a repair of this type may be covered under warranty. One other thing you could try before spending money on it is simply to change the Timing mode in the Windows display settings. Go to "Control Panel > Display", then select the "Settings" tab and click the "Advanced" button. Select the "Monitor" tab and change the screen timing to a different Hertz value in the "Screen refresh rate" menu box. Don't forget to save these settings by clicking "Apply" and "OK" to close all of the Windows settings windows. Hope that helps solve your problem...

Problem seemed to be a short in the power cable to the monitor. Replaced the power cable and for the time, the monitor is working correctly.

SOURCE: Monitor Goes black, or flickers on and off

The high pitch sound is coming from the inverter. It is faulty and needs to be repaired or replaced. The inverter supplies high voltage to the CCFL lamp, this lamp gives the backlight to the LCD so you can see the LCD images.

It may have backlights inverter board problem, check the two surface mounted fuses, also can be bad lamps. Also verify that the AC adapter is putting out correct voltage with load.

I am unable to get any sound from the monitor speaker. Cord is plugged into back of monitor and into cpu. Checked sound settings on Control Panel; made sure mute is not on. Ideas??


Try feedin it with another sound source such as MP3 player, if you do not get the sound, then the amplifier module may have failed and you will be better of spending money on a set of powered speakers instead of trying to get it fixed, you will get better sound any way.

I have one view sonic va1912w-4 monitor. No power from 2 days. So i can checked power cable but problem is not rectifide.What can i do check next step.


Its either going to be the power board or the main board, My assumption would be the power board since those are the more lilely culprits to go out on those monitors.

Since neither one is readly available, check the fuses on the power board and then also see if there are puffy caps. If there is then replace them with ones that are the same UF rating and same or highter voltage.

I have 2 yrs old va1912 view sonic lcd monitor... when i open it the led light still green & it wont open


Hi, You probably have a fault on your inverter board which will prevent the backlights from turning on and illuminating the screen. If you are lucky it may only be 1 or 2 blown capacitors which are easy to replace.

My View Sonic monitor speakers were working fine until yesterday. There is a static sound coming from them now.


Double check all your connections to start with and make sure the lead for the speakers is plugged into the GREEN port on your computer.

Also and i know this may sound silly.

Check that you don't have cell phones or wireless phones , baby alarms too near the computer or speakers.

My speakers give me advance warning of when my cell phone is going to ring if I have it too close to my computer !

Sound on the View Sonic Monitor


Yes, they are on the front of the screen. There should be a volume up and down button right on the front (usually to the left of the power). If there isn't a separate up and down, try the Menu or 1 and 2 buttons.

No sound VA1912wb


I have the same problem but after much playing around with the monitor controls I found that decreasing the contrast allowed me to hear the sound.... The more I decreased the contrast the better the sound became. To test it have a sound track playing and slide the contrast down (less) til the sound comes on. Mine was sporadic but the more I decreased the contrast the better it became. Ok you electronics engineers - tell me why. One draw back on my monitor is now I have raster lines running down the screen.
