my monitors makeing a whistleing noise...
topic basicly says it all. its got a high pitched whistle thats comeing from someplace in the back of the monitor, just started last night. whent on for about 3 hours last night before i turned my comp off. then this morning the whistleing has been comeing and going, its finaly stoped for now. any ideas what might be causeing it, or what it could mean about the monitors health? i know this monitor isnt new by any means, but i hope i dont have to buy a new one any time soon.
NEC MultiSync 6FGp 21" ive had it for the last 5-6 years with about 8 hours of use each day, and i got this thing used. i have no idea how much time was spent on it before i got it. |

it doesnt sound too good to be honest, the monitor might be nearing the end of its life.
I suggest you drop "swimtech" a PM or email, a user on this forum, he is a monitor technican, might be able to help you out in more detail. |

Yeah definately sounds like new monitor time.
My monitor is only a year old and makes these noises as does my television. Its not normally a problem but due to the age of your monitor it may pose a problem. |

one of our monitors did that for awhile...the trick is to change the refresh rate. Some monitors have refresh rates that they "support" but the monitor doesnt agree with. since its old, you cant exactly RMA it but its not as if the poor thing is dead yet.

Aight man, i once had a whistling monitor, Did you try to move it around or give it a little tap. At school i sat next to a whistler and it would require changing its position a little bit, mine at home required a little tap on the top. i suggest moving it before you abuse your monitor

what's the word? flyback?
what refresh you running at .... usually the lower the longer the wavelengths and they generally will cause "whistling"... also it's not hard to repair if it's doing it off and on even at higher refresh rates (some monitors whistle out of the box at 59/60hz....and 70) the monitor has had a good life.... but i have my doubts that it's packing it in..... BTW, try a different power source.. move it to another room and plug it in quick and see what happens.... sometimes interference can effect it oddly...

Flyback is actually right...as usual Judas...
It's the transformer that makes the high voltage for the picture tube, and can vibrate if the coils of wire inside loosen a little. What you're hearing is a harmonic of the output frequency from a coil of wire that has loosened just a bit or the harmonic of the body (usually made of plastic) of the transformer vibrating. The fix requires stopping the vibration. A lot of the transformers (and some capacitors too) are not just soldered to the circuit board, but glued down as well. That's why, if you look closely, you can see this goop looking stuff on capacitors, transformers, and coils in a monitor - they're glued down to prevent vibration which can cause microfine cracks to occur in the solder connections of the device on the circuit board. There are a bunch of transformers and coils in a monitor that handle the horizontal deflection component of the signal inside - any of them can be causing the noise. Other than removing the back of the monitor to expose the guts, and physically touching/pressing on (DON'T DO IT THOUGH - you can get harmfully or fatally shocked if you don't know how and where to touch!) each transformer while the whining noise is happening to find the offending transformer (which is what I would do in finding the transformer to replace it), you can just move the unit, change the refresh rate, or tilt the monitor a little on folded paper placed beneath the base on one corner to change the position of the internal components - any of which change how the transformer or coil will mechanically vibrate. What you are hearing is a mechanical vibration - like a speaker does - but it sure ain't music is it? Other than those suggestions, if it still is just too annoying, take it to a shop...

....so i am correct about the refresh rate though?... i mean, the lower the refresh rate.... the longer the wave lengths in the vibrations... making it low enough to make noticeable vibrations for us humans to hear (some monitors i've played around with would drive either the cats or the dogs nutz depending on the refresh rate ... quite interesting)
I knew it was flyback.. but i kept thinking to myself that "gaud... what an odd word"

pr0digal jenius, if the flyback didn't have a feedback circuit it would fly apart! another-user, the reason for your whining (or singing, or squealing, insert another annoying noise here.....) is the signal going through the wires in the transformers or coils inducing a vibration in the material the transformer or coil is made of, or the coil of wire itself. The plastic or metal that the transformer or coil is made of will only vibrate audibly at certain frequencies - so changing the frequency of the signal that induces the vibration should (theoretically) cause a change in the amount of audible vibration of the transformer or coil. Thats why changing the refresh rate of the video signal, or moving or changing the position of the monitor (which may change the mechanical forces acting on the material the transformer or coil is made of) may reduce the noise. Let us know - OK? We like feedback

well, you where right about the refresh rate. it was set at 75 so i bumped it up to 85 and the whistleing whent away right away. except now ive got a new problem.... at 85 hertz the screen shrinks by about 2/3 inches on each side, and i cant stretch out the display any further then what its at right now. so now ive got these 2 huge gaps on each side of my moniter, but if i set it back to 75 the gaps go away, but that damn whistleing comes back.
you guys where able to fix my first problem, now im hopeing youll be able to do something about this one. while im at it, i think ill throw one more problem at you guys. ill try to explain this as best as i can, but ive also included a picture of whats happening. the lines that you see on the picture, tahts whats displaying on my moniter, the lines are very very faint but also very noticable on some sites, like this site. its kind of a redish black rainbow effect happening, comeing from all 4 sides of the moniter and the arch is comeing towards the center of the moniter. it happens at all times, donst matter what im doing but its always there. any one know what could be causing this one? ill try to get a better picture then what ive got included, hope it gives you some idea of what it looks like though. *scratch that better picture off the list, it looks like complete crap useing MS paint, which is hte only thing i have.* http://www.photodump.com/direct/anot...er/moniter.jpg Last edited by another-user; Sep 2, 2004 at 05:28 AM. |

In monitors particles tend to build up due to external magnetism (natural or by a magnet). It can cause picture distortions, miscolor, lack of color etc. It can really pick on the image. Most monitors automatically Degauss when it is turned on, but if you have an older monitor it may not. Also the manual degauss button does a more thorough job. This may not fix it, but its worth an easy try, Use the Degauss feature on your monitor menu

Okay from there ill leave it to swim, as sometimes an external degausser does a better job. @ 75hz where it makes the lovely sound, did you try tilting the monitor in a different position?

that bites, as i am not a monitor expert i will not be able to give much more advice, unless i stumble acrossed it sometime. Sorry i couldnt help much more but i tried good luck mate

thanks for the help, no big deal that you wernt able to help me completly figure out how to save this thing. in all honesty, i think its just that this big ol beast has clocked so many hours on it that its starting to wear out.

Yeah but most likely if i am right the rainbows are caused by magnetising certain things in the monitor so the red gren and blue beams end up not hitting the right spot. phosphor is the right word? where the beams hit. Does the rainbow ever move? Normally the shadow mask in the monitor can become magnatised and cause the beams to not hit the appropriated phosphor. Is there a fridges, subwoofers, TV, a sort of electic motor, anything that can cause interferance, or have a magnetic component. This may be my last ditch 2 cents to help

/looks around
freezer on the left - check bandsaw on my right - check 188watt subwoofer sitting under the band saw - check like i said, im kinda in a cramped area down here in the basement. this is really about the only spot down here i can have the comp, so im kinda limited on options down here. |

how far away are these components?
Edit: Judging by cramped im guessing pretty close. When the freezer kicks in, does it do anything to the monitor, as with turning on the bandsaw? Now this whole magnetic thing is only a possiblity as what i have experienced w/ monitors and rainbows/dicolorations. i dunno if it is the only cause or even the true cause for this haha, i just found moving a monitor 5 feet further from a fridge fixed my neighbors.

bout 20 1/2" from the freezer to the edge on the monitor, and about 22" from the bandsaw to the edge of the monitor. sub up to the monitor is about 30"

DUDE! Move the sub right away.
My brother screwed up his monitor with his speakers, so we finally moved them and all was well. Oh yeah one more thing...have you lowered your fequency? Try maybe 72mhz? that might work out.
