Is anybody else getting a high pitched whine from the LED driver? I like the lamp and would like to figure out a way to fix it.

I have two of these lamps on my bed headboard. They make no noises at all. If your lamp came with noises, you should return it for a free exchange or full refund. If it's past its warranty period, I hope you're familiar with electronic circuitry if you intend to try to repair it.

Mine is silent too. However, I only have about 40 hours of use with the light and maybe the whine develops over time. I'd try to contact the company, maybe they will take care of you.

I actually did replace one of mine with an LED just to test it out and almost no light comes out of it. The LED lights just don't seem to put out enough light. :( I would love to find some LEDs that do though considering I am running like 15 of these all night long.

I don't have them in lamps that are very tight around the fan, but I have noticed an intermittent fan noise in one of the 150W bulbs I purchased that goes in a lamp that has a glass hemisphere that acts like a megaphone. I'm not sure if it's at a resonant frequency, or just a random issue in one of them. The base can get very warm (I just put my hand on one that's been going for an hour and a half overhead), but not too hot to touch. I'm not sure how hot is too hot, though PacLights may have more information.

I have three lamps like this. I have had no issues so far. Try to return if still under warranty.

I wish I could be of some help and I'm going to point out the obvious and make sure that they are charged up. One thing that I did discover that that this type of system doesn't like compact fluorescent lamps. I'm guessing that the frequency of the lamp is to close to a harmonic of 144 Hz. I just know that I had trouble syncing until I turned them all out. Wish I could be of more help and good luck.

Dear Debra, You have the same problem I had and I found out that I would have to order it and wait and I was so disappoint that I returned to lamp to the vendor for I had became dependent on my lamp and only had it a couple of months. So, I returned the lamp to the vendor. I do not remember receiving a refund but I am not positive.

Sounds like it might be a bad power transformer, or possibly the LED bulb itself.You should file a warranty claim for this problem, I think. If out of warranty, take the power transformer to Radio Shack and have them match it (and the connector) for a replacement; that might fix it for you.

I bought two lamps. One is still working perfectly. The other one was also working just fine until about a month ago and it blew out as well. Still waiting to hear about any resolution to the issue.

I have the same problem too. I just bought this LED 55 in for 2 months and it is making horrible buzzing sound. With the backlight setting to 10, the sound is very obvious, and it will get louder as I watch TV longer, like more than 1 hour.I bought service warranty with Frys, the technician came in and tried to replace the power supply because he thought it was the problem. Turn out the problem was not caused by the power supply but the TV itself he said.I just opened a ticket against Samsung, the Engineer will come over next week to take a look.

I also use a dimmer and no buzzing sound for me .Make sure the hot and neutral aren't switched (black is hot white is neutral)and the fixcture is properly grounded(green).

That long whistle sound pops on when power supply is not sufficient. At least from my experience. Try a much lower power draw device on it like a mini Christmas light set and see if the problem persists.

You can get a replacement LED on Amazon.com. If you take apart the lamp, you will find that it needs to be soldiered... (also, unsoldier the non-working LED. Are you sure it's the LED and not the transformer?

Unfortunately I have not had any luck getting support for mine. Mine won't charge to the point the led comes on. Initially I got an email from them which I responded to but then nothing.Point being I'm not very confident customer support or customer service will be able to help you.

I've read other reviewers comments about exactly that, a high pitched whine like a camera flash charging up. All I can say is the one I got is perfectly silent. I keep it on my nightstand and have never heard anything.

I have a brand new Sony KDL-37W5500 that has the same problem: backlight "whine" when the screen is predominantly dark. I have tried all possible backlight levels and the problem persists on all of them (but setting 2 minimizes it). When I have the volume low at night this whine cuts through and is VERY noticeable.I have emailed Sony customer support about it - if it can't be fixed I will look elsewhere for a TV...

I just bought them a few weeks ago. I understand they have a 5 year warranty. Sounds like the LED burned out, I would request for a replacement.

I have not had that happen with my lamp. Please don't give up - return it for a new one. These are wonderful lamps.
