Open and look at the tops of the capacitors. I bet there are at least 2-3 "bulging" tops. Replace them and the problem WILL be solved;.

Q19WB (vs11443) does not have built-in microphone, see user manual here: http://www.viewsonic.com/assets/034/8841.pdf

Are you using WEB CAM with micorphone built-in?

It does the same when hooked up to another PC?
It may have bad caps as hswon here:

If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on: Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed Optiquest monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/ Post back what you see inside so we can guide you further and it will help out other people in the future also.

You should verify if it the monitor or PC problem, you should try another monitor with this PC or try the monitor with another PC to isolate the problem first.

In that case you need to buy a new lcd monitor.

You need to feed it with another sound source such as a MP3 player to see if it works, if it does, then you PC sound card/drivers/software/setup may be the problem. If it is the monitor, then it can be the power amplifier IC which is not worth repairing, you will be better off spending money on a good set of powered PC speakers instead that will give you much better sound than the monitor's speakers.

Hello. Check to be sure that the speakers did not get turned off. To do this turn on the monitor and use the remote to get to the menu and then to the audio area. Once there you will see the choice for having those speakers on or off. Joe

4 thumbs up please. ty.

Considering the slow discharge of the cap, it is probably good and without an RCL meter with loss capabilities, it would be tough to condemn it.
In most cases I've seen, the larger filter caps are not at fault but rather caps in the range of 4.7-100uFd that are used in the feedback path. The voltage ratings are seldom over 50VDC. These are exposed to high frequencies and if a standard electrolytic is used (they are cheaper) they will eventually fail due to the decay of the chemicals in them.
You might check for a radio amateur club in your area since one of the members might well have an RCL bridge/meter with DF capabilities. If you find one with more than one frequency range, a bad cap will show a major decrease in capacitance and increased losses at the higher frequency.
Good luck-

Well without any more information from you i would check the power supply, the back light, the inverters and the list goes on.

Not much help because you did not mention if there is a stand by light weather it is blinking or not.

et me know Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/edwy_1a56970cf1ea4620

Look for bad caps in the power supply as shown first, then post back what you find since it can be more serious problems.
