Strange hissing sound and smell comes from the monitor

Whenever you experience an unusual smell coming from anything electrical, always turn it off and/or disconnect it from any power source until you learn more about the problem. A fire can make make any problematic device seem suddenly unimportant.


An extremely common component in nearly any electronic device is a capacitor. The sizes vary from baby-tooth-sized to bowling-ball-sized found in the power box for most photography studios. The hissing sound is likely caused by one of these. The noisy capacitor may be going bad or another component or an electrical short may be causing it to get too much power. I've attached a video of what happens when capacitors get too much power.

An electrical short could also be causing both symptoms. If the smell is similar to burning organic matter, you likely have an insect (a crispy critter) that can be removed to remedy your problem. However, an electrical burn usually releases gases from burning rubber or plastic and has a distinctly different type of odor. If that's the smell and you are handy with a soldering iron, remove the cover to your monitor and look for signs of burning or overheating. Otherwise, the task should be left to an electronics shop for repair.

My studio monitor, after it is at a healthy volume for a while starts to pop and distort.....and when I turn the volume down the monitors puts out a hard hum, pushing the speaker out.....does this sound...

That does indeed sound like a failing capacitor. If you want to repair it yourself look for a 1 or more capacitors with a crack in the top. You will need to replace the capacitor with an identical rated one. Otherwise you will have to replace the monitor. Be extremely careful as capacitors can hold a deadly electric charge even when unplugged and turned off.

My problem is no sound Per the computer it shows it is working and I have tried everything to figure out what the problem could be.

Please cool down & smile (very important) ha ha...
Now, go to your control panel / sound or audio / audio tab / sound playback! Here you need to choose your proper default output device. ( the said path depends on the OS you are using)
Apply changes & exit. BINGO!

Problem with DELL 2408WFP

I have similar problem.  I'm using the HDMI connection from my PC to the monitor and when I connect my audio out from the monitor I get hissing and popping sounds along with the audio.  It sounds pathetic, I also hear the music and audio along with the hissing and popping.  
If I connect the audio to the back of the PC the sound is crystal Clear.  I am using Vista 64 bit with NVIDIA GeForce 8600 GT video card.  Trying  to Google to see if others are are seeing the same problem.  I just got my monitor on Oct 6.

Monitor won't turn on.

Does the cord plug directly from the wall into the monitor, or is there a power "brick" adapter between?

If there's a "brick" listen to see if the hissing is coming from the monitor itself or the brick. If the hissing is coming from the brick you may just need a new power adapter.

If there's no brick or the hissing is coming from the monitor, the monitor probably needs repair. With the price of LCD monitors these days compared to the price of labor, you're probably better off getting a new LCD monitor. Just make sure you take your old one to a proper E-Waste facility so it doesn't pollute the environment.

Power Problem

The hissing noise on your speakers is because of arcing. Do not try to operate repeatedly or you may do severe damage. The most likely culprit is the inverter board but you will have to disassemble the monitor to find out. Any loose connection that results in an arc will create noise on speakers. Hissing is usually a result of the high frequency/ voltage output small enough amperage to not blow your power supply If it were a DC arc you would just get a one time pop.

NEC P1250+ hisses and scrren blips intermittently

I had the same problem. Your monitor is warning you of failure. The hissing sound is the picture tube powering up. The momentary blank screen is when the power supply for the monitor has become hot. Your monitor is getting ready to quit. My suggestion is to buy a new monitor. To have a tech repair it would be more expensive then buying a new one.
