I got the I-Inc if281 which is almost identical to the HannsG 28. I got it on 12/7/09 and it says manufactured in July 09. I have had no problems with anything really. There is no noise, in fact my area is quiet (at work) and I don't hear a thing. I would exchange yours if you can. BTW CompUsa had the IF281 for <250> last week.

I had this humming/buzzing noise problem when I bought Samsung 21". The monitor started humming after it was on for 5 minutes. It was not loud, but annoying. I returned it to Costco. Don't know what problem that was.

I can't hear any buzzing from my CFLs. But that might be just my hearing. I see that another answer talked about the lights failing quickly. While I have not had that problem another customer did. The bulbs come with a support phone number and are distributed by Home Depot.

We've had the ld350 for a couple weeks and it does the same thing. It makes an annoying buzz when we turn the backlight down lower than 75-80. Other than that we are liking the tv and hate the thought of having to return it, but this is very irritating with the sound low at night in the bedroom. Also, afraid it may get worse.

Haven't noticed a hum. We have 3 of them in our kitchen and, even when things are quiet and the lights are dimmed or all the way up, haven't noticed anything unusual. Wondering if you got a defective batch?

The switch itself does not ever emit a noise that I can hear. The actual bulbs though, (I am using dimmable LED bulbs) will start to flicker slightly and emit a slight buzzing noise when this dimmer is turned below ~35%. I am able to safely dim down to 40% without any flickering or buzzing whatsoever.

I have never had that problem. It is probably just your particular monitor. You need to contact Amazon and they will get you another or do something to help you out.

Just got one on Tuesday 2/9/10. Same buzzing problem, but found out it was getting some type of interference from our space heater. Look for something that may be causing the same thing in your home. We turned off the space heater and now we're colder, but NO BUZZING. Hope this helps!

No loud buzzing. No migraines. No brightness problems. Works great. Try Gunnar glasses to help with with reducing glare for any monitor.

I've had best buy out twice now. The first time to replace all the screws in the back of the tv and that helped for about 1 week and the buzzing or humming sound came back. Best buy came today and replace one of the boards on the tv and i'm hoping this will fix the problem.

No, I don't have that problem. I never noticed a fan running until I read this email. Now, I can hear a slight hum occasionally. But nothing you should ever notice. Yours is not right.

Cannot help you, if still under return timeframe, return it. I have two units, one used for three years, one still new in box, even un-opened--was going to sell it so did not want to open the box, but decided to keep it since now discontinued. Your post reminds me--I should take it out of the box and check it. Question--are you sure it is the monitor and not your video card in the computer, or interference from some other device? Check online for like symptoms.Love this monitor. If you can find a fix, and otherwise in good condition, worth fixing yourself.

Truthfully Im 100% sure what the issue is with your monitor it is the 27" correct,and when you talk about start you mean when the computer starts up rite?? Well I know for sure my monitor {when I sleep or turn off the computer a red led starts to blink on the lower rite of the computer} that lets you know the monitor is working normal...also try different cables I run mine mostly on HDMI hope that helps I haven't ran in to this issue as of yet lol.

No. I pulled mine apart because of the same issue and found it was the back lighting (shine a flashlight when it is on and you will see your screen still works, just no backlight). The lower CCFL wires for mine had a bunch of unidentifiable crystal like corrosion which might be due to bad SIC insulation but my CCFLs worked fine. I cleaned the corrosion and tested good. Prior to that I swapped out all of my electrolytic capacitors on the supply board. Still nothing. Considering getting a new one to match my good one or buy two new monitors and move on.....not sure yet.

None of my dimmers make any noticeable noise. Some incandescent bulbs can be noisy when dimmed, especially when first turned on. Buzzing at the switch can indicate a wiring issue or improper usage - driving a non-dimmable fluorescent or an inductive load like a fan with one of these could certainly cause noise, and is not recommended in any case.
