Has anyone had issues with the LNxxA750's power supply making noise? Either a hum, buzz or squeal?

Have not had that issue, Milenkod, but occasionally I've experienced another odd behavior. Every once in a while when the tv powers up the colors would be all messed up, where it casts a sort of purple haze over everything. I disconnected the HDMI cable going through my receiver and tried a direct connection between my cable box and the tv. That made it better (less frequent) but didn't eliminate the problem entirely. I still had to reach behind the tv and disconnect, then reconnect, the cable into the HDMI port to get a normal picture.

However the other day I tried a different HDMI port (No. 4) and that seems to have solved the issue, at least for now. Has anyone else experienced anything like this? I have the 40" model, and this is the only problem I've had since buying it new.

Great...I tried to delete the duplicate post and it deleted them both.

I think I may have found the issue to the power cycling problem. There was an early firmware update that resolved this issue and it appears that this TV may not have had that update. There's no way to flash the mainboard now and I'm stuck with wholesale replacement of the board. Less that $ 100 on eBay for a salvaged board. I may try this route before giving up.
