Buzzing sound coming from monitor speakers

A high pitched buzzing sound comes out of the monitors speakers when no audio is playing. The monitor is hooked up to a macbook. This problem just arose when I hooked my laptop back up to the monitor, but I have not changed any settings. What should I do?

Re: Buzzing sound coming from monitor speakers

Check your leads, chances are it's a faulty/dodgy lead coming from your macbook to the system.

Sounds like the common Bad Capacitor story! If your monitor is not under warranty and you have any soldering skills this is only a 10 dollar fix. There are dozens of tutorials on youtube that will walk you through this. Search "Monitor capacitor replacement".

We have a buzzing sound coming from the monitor speakers when we go to ANY internet site. It is just loud enough to be annoying!

LOL. This is a common, easily solveable problem. Remove your cellphone or anything that emits radiation of any sort from the general area. Don't believe me? send a text message while sitting net to your speakers. It does this even if you arent sending a message because your phone sends intermittent signals to the cell tower. the radiation being emitted from the phone does weird things with the magnets inside the speakers.

The power supply of your HP Monitor is failing - it is not able to sustain the voltage needed to maintain picture.

It is possible that solid-state components could be replaced on the circuit boards to fix this situation, but for the trouble and expense I must recommend replacement.

I hope that helps.

Buzzing is usually caused by bad audio ground connection. Try insert and reinsert the audio cable first. It can also be the sound card. Try using the MP3 player as the sound source feeding the monitor, if it still bad then it can be problem in the DC filter caps in the power supply, or bad sound IC in the audio board inside the monitor. Please post back what you find.

Comes on but goes in and out while making a slight buzzing.

usually a buzzing sound is the disc capacitors going bad. you will need to open the case. run the monitor and find the buzzing capaitor and replace it.

I am experiencing a high pitched buzzing noise coming from the dell monitor #cn-0p0151-64180-3a5-3642

CRT monitors and TVs do this after some time. It is caused by high frequency alternating fields - think transformer - when things get old and loosen up enough to vibrate.

The good news is that it is time to upgrade to a modern flat screen monitor, and this will be cheaper than repairs on your old tube.

There is a loud buzzing/static sound coming from my monitor. It changes pitch and sound a little with different screens. The visual display does not seem to be effected. Just a terrible sound. Any ideas...

Start by getting a can of the electronics spray air and blowing out and areas that may collect dust.

Also jiggle the power cord attached to the monitor and watch to see if it changes the monitor or the squealing at all.

Seems more like a lose power connection, but eliminate the simple possibilities before moving toward circuit board issues etc.

Also do you have any other high powered electronic devices near the monitor?

That can effect it's performance as well.

Sound from monitor speakers distorted and high-pitched

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

Good picture for 30 seconds then screen goes black with a faint ghost of the image

the 12V is for speakers.. the 245bw takes regular 120V AC (same cord as your computer)

the buzzing is annoying, though. i don't know if it's a "feature" or just a side effect.. ie, if i could take the case off and poke around, i would. 4 times out of 5 it's some dumb piece of tin reverberating from a transformer or something..
