Re: Smoke

Sound to me like it's toast. You probably will be ahead to get a new one, rather than trying to have that one repaired (if you can find anybody to work on it!)

Where the electricity cable plucks into the monitor there is a buzzing noise, and a few times the screen just went black. yesterday it did not come back on. what do I do?

Look for bad solder joints on the 3 legs of the AC inlet.
See pictures here:
BenQ makes DELL and HP monitors.
Also inspect the caps for domed tops.

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.

This is general LCD monitor advice. I don't know your specific model. Your problem, however, is very common on many different monitors.

In 90% of cases, the problem is one or more failed electrolytic capacitors on the power supply board. They are a simple matter to replace, but require desoldering the old ones and soldering in new ones, as well as general electrical/electronic safety practices.

If what I've just said already makes sense to you, then you're probably qualified - go ahead and replace them. If I'm talking greek, then go find an electronics nerd - some goofy looking guy wielding a soldering gun should do.

AOC 19MVWK - no image or rainbow vertical lines

It seams like connection is bad. If it is black but light show that is on or in stand by than it is the cable from monitor to computer if monitor is totally off when it is black either the electrical connection is bad or the power plug is broken.

Monitor suddenly goes black

Is this monitor and LCD flat Panel? If so this is due to a bad power supply, an inverter board going bad or LCD backlight bulb blown. When the backlight goes bad it gets just enough power to start up, but when it is on for a long period of time it goes black because the bulb is not stable enough to hold the charge because it is going bad. These bulbs can be changed, but they also can be costly!
