high pitched whine lcd monitors pricelist

I have a cheap LCD that sometimes exhibits this problem (Chimei CMV 938D). For me, the most effective solution is playing with the brightness levels - it never whines at 100% brightness. I"ve always assumed it was the capacitors, though I"ve never been sufficiently motivated to take it apart and investigate.

I"ve had this screen for 2 years now, and it"s done it since it was new, so while it might be an early warning of death, I"ve always just figured it was a function of a cheap build. Admittedly I don"t often run mine in the brightness range where it whines.

Hi. What you are experiencing is a form of coil whine. Try messing with the monitor settings in the included monitor on screen controls. You mentioned adjusting brightness on a previous monitor. Did you have any luck adjusting the brightness on this monitor?

It looks like your monitor has multiple inputs and an external power brick. I would try switching to a different hdmi port and moving the power brick as far away as possible. It may be your power brick that is emitting that harsh noise, and not the monitor itself. Try another power brisk. You can try listening to the power brick when unplugged from the monitor to see if it emitts that specific noise. This is not the most scientific test, as the brick is not under load when unplugged from the monitor, so it may not produce a coil whine at all. If it does, find a replacement / RMA from samsung.

It might be a little frightening when your TV makes a high-pitched noise. However strange as it may sound, most manufacturers say you shouldn’t panic when this happens. A high-pitched sound produced when turning on your TV is completely normal.

This sound is produced by electrical charges made by the TV to power the pixels that create the images displayed on your screen. It is essential to note that the high-pitched sound produced when you turn on your TV shouldn’t be too loud either that it is audible when the TV volume is set to normal levels. Additionally, if you are getting no sound from TV there could be a different problem.

An unusually high-pitched noise from the TV could also mean a hardware malfunction. Fortunately for you, we have compiled a step-by-step guide on how to fix high-pitch noise from even the most highly-acclaimed TVs.

Several things could lead to a high-pitched noise from your TV. Different components inside the unit can produce these noises. These include the deflection yoke, horizontal flyback transformer, and horizontal deflection circuits, among other components. The connections to the tv such as the HDMI port may also be faulty but you can always learn how to fix an HDMI port on the tv.

A high-pitched sound might not necessarily point towards a hardware fault in your TV. However, before getting to that conclusion, the following steps will help you fix the issue.First, unplug any devices that might be connected to your TV unit and pause to listen if the high-pitched sound disappears. If it does, you’ll have to plug in one input device at a time to find the source of the noise. It should be noted that a faulty connection could be responsible for multiple problems that can arise with your TV like showing a black screen. Or if you are watching something with a soundbar, a faulty connection could cause the sound to be delayed on the TV.

A high-pitched sound from the TV will also be amplified depending on how the unit was installed. Glass, wooden, or wall brackets where the TV is positioned can increase the tone of the noise. Position your TV on a rubber surface to help muffle the sound.

Ideally, all TVs make some noise that can be heard in a quiet room with your ear placed on the unit. This is quite normal.If you have a home theater system or a soundbar connected to your TV, the high-pitched noise gets louder when you increase the volume. You will need to check your connections, including HDMI or RCA, for faults or physical damage. If you notice any wear and tear, replace them with higher shielding options.

If you have tried all the above options and you are unable to tone down the high-pitched sound, it could be an issue with an internal hardware component. You may want to try fixing the resolution on the tv too. But if it fails, it is essential to seek assistance from the manufacturer on your TV warranty status.

In normal operating conditions, there shouldn"t be such high pitched noise with monitors. Please connect the monitor to different AC outlet and try to lower the refresh rate.

1. Check the video cables. Make sure the cable is securely connected and if possible change the cable. If using an LCD TV in Video mode, make sure the cable is connected to the correct input.

"Next, I picked up a u2713hm (...) but it has a high-pitched whine on certain pages (seriously, you can"t make it up, it"s like a hummingbird drilling into your skull). No sparkles from the AG coating, tons of inputs... but that buzz."

"Excellent display visually, except for one annoying factor: when the screen is entirely filled with ca 18pt type (approx. 55 lines of it), there is a high-pitched audible whine coming from its electronics. (...) If you then slightly change the zoom you can hear the pitch change -- ca 3500 Hz."

"I originally awarded this monitor 2 stars and said that it would be a great monitor once the issues have been fixed. The issues being yellow light bleed, cross-hatching and a high pitched whine that may be present when viewing certain web pages. I have now lowered my review score to 1 star and I recommend that you avoid this product."

"I thought I was good to go and that I didn"t have the buzzing issue until I brought up a word document in "full screen reading" mode at which point I could hear a high pitch buzzing sound. If I take the document out of "full screen reading" mode it goes away. I can produce this result in an off/on/off/on fashion consistently."

"So why am I thinking of returning my U2713HM monitors? By far the biggest problem I have is this buzzing sound that consistently manifests itself on text-heavy pages. This happens with both U2713HM monitors that I have, and is commonly reported by others."

The monitor does looks great apart from that, but the high pitch noise it makes on text heavy pages really makes it unusable (for my purposes anyway). Is this a known problem?
