High Pitched Squeal, Samsung LED

[SneakyStuff]

I recently purchased a Samsung UN39FH5000F. I love everything about this set except one minor detail...

I noticed that when the set is on standby there is a high pitched noise that seems to originate from around the power supply. When I plug in my Xbox into the first HDMI port (set and Xbox are in standby) this noise intensifies. When I connect my computer to the other HDMI port, the noise becomes even more audible. Similarly, when I unplug each device the sound will diminish.

I have tried running the set off a seperate power outlet/surge protector from my Xbox and computer and the results are the same.

My question to you is this: Do you think I have hit a simple case of bad luck? Perhaps a bad board/cap within the set? Or do you think this might have something to do with my setup or an electrical issue within my home? My greatest fear is returning the set for a replacement, getting home, and finding that the exact same thing is going on, resulting in me returning the set yet again!

I appreciate any useful feedback

I think its the unit, I remember a PSU on the computer doing the same thing. To make user you can plug in the TV in another room or maybe in the garage, but I am pretty sure its a bad unit.

PSU windings weren't glued down well, it could be the unit but since these things are mass produced it generally means the PSU selected for this unit is not noise dampened at the factory. Also its pretty much hit or miss price doesn't seem to be a guarantee of quality. I spent $3,000 a few years ago on a "medical grade" computer monitor that had a crappy noisy PSU that was so loud I could hear it from 10 feet away. Was so annoying I sold it a huge loss on ebay.

Of course if you aren't afraid to DIY and void your warranty I think there are ways to fix this yourself
