Hear a humming sound seemingly emanating from the back or bottom set. Is this from the lamp?

Its most likely the fan . Often just checking the fan blades for dust buildup then removing the dust will fix the issue, other times the fan will need replacement. You can get the fans for that model from if you end up needing one.

Samsung hdtv hums

You can try a hard reset: Unplug TV from AC mains and remove all cables from TV. Wait about 2 hours and let the tv cool and replug to AC power and redo the cabling. Switch on the TV and see if it works..if the fan does not run then you may need to replace the fan as its vital part which cools the tv part ,to fix this issue....

And use his link to replace the cooling fan....

Good luck...

Our TV is making a loud humming noise. We think

It's likely your color wheel rather then your fan. I've replaced quite a few of these and the fans are usually good. Get and estimate - I generally charge $250-350 Total
also google your model # and color wheel to investigate further.

Humming noise coming from the back of t.v. sounds like the fan
