Hello

There are a few different reasons that can cause this issue, I'll try to be succinct.

1) Meeting or exceeding the switch load capacity - the switch's capacity should be embossed on the back of the switch. Total the bulb wattage on that switch and see how close you are. Even 375-425W on a 500Wmay buzz, a higher capacity dimmer may be required. 2) Is it actually the dimmer? Some switches actually cause the bulbs to buzz. These may be resistor-based dimmers, you will need a dimmer with an auto transformer component. 3) Is the dimmer rated for the bulb type on the circuit? A fluorescent rated dimmer may buzz with an incandescent bulb and vice-versa. 4) Some track lighting is low-voltage" rated, there are specific dimmers for this application.

Hope this helps.

if you are saying that the dash lights go dim and bright while driving it could be a loose connection of the wiring harness behind the speedo nacal.

I have a GE profile spacemakeer JVM1860DB worked great until Saturday now when I do anything to it, it just buzzes and the microwave will not work did notice the lights are dim and the night light is dim...

The problem is more than likely a bad magnetron, especially when there is a loud buzzing sound and it is laboring. There are two additional parts that could be a factor, the high voltage capacitor and diode they work in conjunction with the magnetron to generate the high voltage to heat the food. To get it repaired professionally with parts and labor will be high.

Acer lcd screen p191w makes a buzzing noise when turning on and the screen is very dim. then it shuts off. can this be fixed at home

Not safely and not unless you are confident and competent with electronics. I would put the dimming down to a failing display circuit, but the buzzing sounds as though a short is developing. I would take it to a tv repair shop who can advise better and maybe replace or repair the components

Follow the ground wire ( black to the raditor suport and reconnect it or add aground wire from it to the battery ground and it'll work good. Bet it goes out if you unplug the other headlightas it's grounding thought the other light.

This, unfortuantely, is one of the usual challenges associated with dimming. The buzzing usually gets worse at around the 1/2 light level point. I don't think the issue has to do with whether the lamp is halogen, but rather how the lamp is physically constructed - and that differs from manufacturer to manufacturer. Long story short, I would take note of the lamps you purchased, and when replaced, I would opt for a different manufacturer.

My samsung 42 inch hdtv is making a buzzing noise

First. The whirring or buzzing sound you hear is the Color Wheel and it needs to be replaced. Second, since I do not know when and if the original lamp has been replaced it is a good idea to replaced the lamp. The bad Color Wheel is the one causing the set to shut down.

Audio system buzz with dimmer-controlled track

It may be too late given the date of this post, but the buzzing has nothing to do with the bulbs (usually, dimmers and lamp buzzing are a common problem which is why you probably got the suggestion), but in your case, you have radio-frequency interference from the dimming circuit leaking into the audio circuit. The best things you can do is either minimize the RFI, or separate the audio circuit away from the dimming circuit. Based on what you're saying about the PC input, it sounds like the main culprit is that specific audio wire going between the PC and the sound system - can it be run differently so that its further away from the dimmer/circuit. Are the PC and the dimmer on the same breaker? - If so, maybe noise is radiating from the dimmer into the PC through the power wiring - putting on different breakers could help.
One more note, the best dimmers, in terms of RFI performance, are reverse-phase control dimmers (usually designed for electronic-low-voltage... and be careful because they often get confused with magnetic low-voltage... and those will not help. Without going into too many specifics, the ELV dimmers have a much softer on/off/on/off dimming cycle when compared to standard incandescent dimmers (this is a circuitry thing with a much more complicated explanation), but as a result, they tend to have significantly fewer issues with RFI. They can be an expensive solution for simple problem solving, but the MIRELV-600 should do the trick (again, don't be fooled, the MIRLV-600 is the magnetic low-voltage product, and for what you're doing, won't help).

Red power light and buzzing sound with red lamp light.

My Sony lost its picture and had a flashing light. Unplugging for 36 hours solved the problem.
