Viewsonic Monitor sound problem

Unable to hear sound from built in monitor speakers on Viewsonic model VX1945WM. All sound card drivers are installed with no conflicts. If I install external speakers the sound works. The internal monitor speakers did work at one point but just quit one day. Suggestions? The sound on my Viewsonic VA1912w quit working when I pressed the button on the On Screen Display "Restore Memory".I pressed the button in an effort to eliminate the flickering on the screen and that did not change. I subsequently downloaded and installed a Vista driver and the flicker was solved. As for the sound, when I press the buttons to go from ANALOG to DIGITAL, I get sound for a couple of seconds. When I press the power button I will get sound for a couple of seconds before the monitor goes off. I have twice spent more than an hour with Viewsonic Tech Support and they have no solution.

SOURCE: Monitor Flickering and Sharpness control is disabled

it will probably be the graphics driver you need to update as XP probably loaded generic a graphic driver. The monitor should be ok with a standard driver.

PLEASE read Carefully so here is a fix for the green blinking light ...the monitor is going into shutdown....protect mode......THIS is ...Only for the seasoned electronic service tech ......YOU NEED TO BE into Electronics ..or have electronic background and know how to solder to do this........I been doing repairs for 30 years now ..............After extencive troubleshooting and replaceing a lot of electrolitic caps on the inverter board and spending about 10 hours doing so ....i decided to eather go for broke and blow this up more or trash the unit......................Well my blinking light deal went away...my monitor you could see it trying to start and just shut down............first of all make sure you have no broken solder work on the inverter board or swelled up caps ...Thay use lead free solder so the solder work sucks also...........I did pull the main buss line from the inverter pc board that runs the transformers to test to see where the trouble is.....found its at the high voltage end of the inverter board and The viewsonic 922 uses a protection ic on the inverter board and it tells the controll ic whats the High voltage status of the inverters.....I soldered a 47uf @ 25 volt cap on pins 7&8 of ic-u2 [ bi3101a ] Pin 7 is posivtive pin 8 negative of the cap.... and then soldered pins 10 and 11 togeather on the other side of the ic.......ITs fooling that ic telling the main controll / protect line thats all is well........I would guess the whole deal is LOW inverter voltage or maybe a surface mount device thats going to go........could be low resistor tolerence also............The monitor been working for a week now.........Always on.....anyways........YOUR problem may just be bad solder or bad caps...........if you Have a electronic background or have a friend that works on electronics have him look at the caps.see if any or swelled or rounded on the top of the caps..Also chect the main plug that goes to the LCD backplane to make sure its in correctley................if all that checks then the problem is ON THE INVERTER BOARD ONLY ......befor doing what i have done......I also have a Viewsonic VA-800 that had some of the same problems also ,but it had a lot of lines on the video.......I replaced the,,,,, 2.2 mic @ 50 volt cap in the middle of the main board on it and its still running.....but has about 3/8 of white traces following all the words on the desktop...[[[ anyone that knows this fix i would like to hear from ]]] ..........NOTE if you dont know about electronics...dont attemp any of this......their is a lot of voltage on the inverter board........my answer is that these monitors are JUNK...poorley built units.....

Common failures in this monitor is the 470uF caps in the inverter section (close to the inverter transformers), but you should replace all the caps in the 5vdc and the 12vdc as a whole set. See example of failed VIEWSONIC monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

Sound no longer comes out of monitor. I believe nothing is muted. I replaced cable between monitor and desktop. Any suggestions.


You didn't provide a model for your Envision monitor, so I can provide specifics - but here's a few things to try: (1) Start an audio program on the computer (mp3, CD audio, movie, etc. (2) Disconnect the audio patch cable from the computer's speaker jack and plug in stereo headphones. Adjust the volume on the computer's audio control panel to set the volume. If you're not receiving any sound - make sure you're plugged into the speaker jack (this is often the green jack). If you now hear sound, continue to (3). If you are unable to hear any sounds - your problem is INSIDE the computer. More on this later. Continue to the next step. (3) Disconnect the headphones and try the audio patch cable between the computer and monitor again. Make sure you're using a stereo cable - it has 2 individual contact points on the plugs - mono cables have just two. Pay close attention to the jacks if more than one are offered on the monitor (some monitors have power output jacks, etc.). Select the "LINE IN" or "SPEAKER IN" jack on the monitor. Be sure the plugs are firmly seated into the jacks on both the monitor and computer. (4) Check the menu settings of the monitor to make sure that the speakers are enabled (or not disabled as the case may be).

if you were unable to hear audio in step (2) above, there is a problem with the audio circuit in the computer. Some things to check are: Is there a volume knob on the sound card that is turned to minimum? Are (all) the correct drivers installed for the sound card in control panel? Is the sound card enabled? Does the sound card have a problem indicated by an "x" or "!" on the icon in control panel? Many times, "uninstalling" the device in control panel and the "scanning for changes" to reinstall will solve the problem. Other times, it is an output device issue: Have you selected "Speakers" as the output (not HDMI or Digital Audio).

If still unable to get sound working, provide the Envision model number along with computer name & model or the sound card name and model. If the sound is built into the motherboard, provide the mother board name and model. With that info, it will be easier to get the info you need.

Hopefully, you got the sound working with the tips I provided above. Please rate my reply. Thanks.

I don't have the sound disk anymore and the monitor is not producing any sound. When I try to download the driver my computer says it doesn't recognize my model VA1930wm


The monitor driver is for your computer to recognize all the resolutions your monitor can handle, there is no sound driver for the monitor to work since the monitor built-in powered speakers are jsut that, powered speakers, same as the one you buy if the monitor does not have built-in powered speaker.
You can test the monitor speaker system by feeding it with the MP3 player or any sound sources.
It may have bad power amplifiers IC. You will be better off spending money on a good set of PC powered speaker system that will provide a lot better sound quality than the quarter-size speakers in the monitor.

Hi , I own a viewsonic LCD monitor model va1912w. My system has Windows XP. There is no sound from the monitor even after connecting the sound cable from CPU to monitor's audio jack. I have already...


http://www.viewsonic.com/support/downloads/drivers/?prod_name=1912

Try the above link for Vista or XP drivers which may be used with Windows 7 in some cases.

The va1912wb came up when I searched under 1912.

This driver is available directly from the viewsonic.com site.

Uninstall the other driver if possible.

ViewSonic VG2030wm speakers not working


you are unable to get an image on your ViewSonic monitor, first check that the necessary cables are attached correctly and that the proper drivers are installed. ViewSonic offers drivers for download directly through its website (see Resources).

Some LCD monitors use a VGA input while others take advantage of the newer DVI interface to provide a connection to PCs (some ViewSonic monitors offer both types). When connecting your monitor for the first time, you'll need the right type of cable for both your monitor and computer. In some cases an adapter may be necessary to convert the DVI signal from your monitor to work in a VGA input on your PC.

Check that the VGA or DVI cable is tightly attached to the back of your monitor and to the back of your PC. Use the small thumb screws on the ends of the connectors to keep everything tightened in place, which will prevent the cable from getting loose.

ViewSonic monitors also use a power cable to plug into a power source. If the power light does not comes on, check that the power cable is inserted fully into the back of the monitor and that it is plugged into a working wall outlet or a reliable surge protector.

Drivers cannot be loaded...windows does not recognize monitor


I think after your crash you are missing the drivers for your graphics card and not the display. Check what kind of graphics device you have and see if you can find the drivers for that.

First.. have you installed the drivers for the sound card.. would check that first.. if that is ok.. then check the output of the computer with another pair of speakers or a pair of headphones.. additionally i would check the speakers in the monitor by connecting to another source.. such as an mp3 player or portable cd player..
