1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.

It is quite likey that either the inverter or backlights are faulty. When backlights go faulty they usually show a colour on the screen usually red. Backlights have connectors going into the inverter and they are usually two of them, one for the top part of the screen and the other for the bottom. The inverter is the easier one to replace. Backlights are expensive and sometimes not worth replacing. Check capacitors as well to see if any are bulging at the top and replace. I hope this helps.

The most common cause of this is a failure of the filter capacitors on the power supply board. If you can do a little soldering then the repair is easy to do. You will need to replace the bad capacitors and then the unit should be as good as new again. Here is a link to additional information on which capacitors you will need to replace.

I hope this helps you out,

May or may not, you should always repalce them in a set of caps, it will usually has two or more caps for 5vdc power supply section for the logic board, and two or more for the 12~18vdc power supply section for the backlights circuits. The backlights circiuts, lamp asemblies may have failed also.

Capacitors kit: he can make you a set of caps for you.
Or just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

It sounds like you have an issue with the monitor's power. Make sure all connections with the power cord and audio cables are secure. If this does not resolve the issue and the monitor is under warranty you may want to RMA it.

I searched around on the web and found somebody mentioning the power source. I live in south Florida and we do get power surges almost daily. It seemed too good to be true but I decided to try it so I unplugged my monitor from my surge protector and plugged it into another outlet and BAM!!!!!! Crystal clear and like brand new!

It must have been the surge protector.

So if you have a fuzzy monitor one thing you CAN TRY is to change the power source or outlet. It worked for me and saved me a few hundred dollars.

If you have not connected an audio cable to the monitor then you cannot get any sound from the speakers.
Connect an audio cable from the audio out jack on your computer to the audio in jack on the monitor.

If the screen is completely white, there is a couple things that could be wrong with it. It could have a defective internal digtal board, or one of the internal cables has a bad connection. The only way to check would be to open the monitor and check the cables and board. Not really worth the money to have it repaired professionally, since the price for a 19 inch LCD are so cheap now a days.

Failing internally, unless you suspect the cable or graphics card?
Repairs are possible, but unlike the older CRT monitors, expensive and sadly uneconomical. CRT screens do go over time and the loss of a colour channel is usually the 1st sign it needs replacing

Your video card may not not support the current setting of your desktop resolution.
Right Click on your desktop. Select Properties. Appearance Settings. Adjust your display lower like 800x600 or 1200x900.

It's either your monitor or your video card does not support the resolution that you choose in your computer. Try to set it to the optimal or best settings that your computer can handle especially your monitor as this is the main culprit for this kinds of issue. Another thing to check is the cable that is connected to your monitor and your computer. It may just be a bit loose and needs to be plugged in firmly.

change the large condensers in the power board that will work.

I was having this same problem with my monitor for days and it was driving me nuts, and being in IT not being able to solve it was even worse. My Viewsonic is a VA2232wm with built in speakers, I muted the speakers on the computer and using the control buttons on the monitor with no luck, it was still clicking. I move my laptop to and from my desk all the time and everything goes to the monitor via a USB docking station except for the audio. The audio cable I have to plug in separately. In my haste, the last time I connected the audio cable to my laptop, I put it in the microphone jack instead of the speaker jack. Once I moved it to the right jack, the problem was solved. Not sure if this will resolve your problem or not, but I hope it helps.

Most likely it need to be set to receive input on the digital source. Alternatively, make sure you are plugged into the correct video output on your system. Sometimes a computer will have an onboard display adapter as well as an expansion card display adapter, if this is the case, make sure you are plugged into the expansion card, as onboard is probably disabled. Failing that, you may need to adjust your resolution to a resolution supported by the display, try a known good DVI cable, or try the monitor on another computer.
