Plug out speaker and sounds still, plug out backligh conector from power supply and when power on start bit loud then is hard to hear need get close and sometimes get louder and then is not loud but still present.

Disconnect the lvds cable from t con and same symptoms

Turn off the tv then unplug a cable between the power supply and the main logic board and automatically the screen turn on too bright and the sounds is loud,so higher is the brightness in the screen louder...

[QUOTE=martyparish;636904]It looks like the capacitor next to the heat sink(the longer one) is bulged. It could be an optical illusion, but look closely to see if the top of that cap is bulged out.(or any of the other caps)

Also, do you have a multimeter? If yes, check the voltages on the power connector.[/QUOTE

I check all caps and look ok check the one you told me and look fine voltage from electric cord is 123vRe: Samsung UN46F5500 electric/overload sound comingbfrom power supply...

Hi evryone

Found this beauty behing best buy next to the dumpster when i saw the thin and light it is though can fix it! was made in 2013 so im sure the most usage life on the tv is no more then year and half. When i plug in the tv surprise works i mean all but i hear a electric sound comimg from behing remove the back lid i figure out is coming from power supply the hot side also when the screen brightness is higher the sounds turn louder search in the forum someone had the same issue with a sharp but the tv shut off after couple seconds and was a bad fuse in a inverter board....
