Need fuse TV was on and then it made a noise and went out

It's obvious that the power supply failed. The most common parts in a power supply are a thermistor or a voltage rectifier, possibly even a voltage regulator. diodes or resistors can act as fuses too. A ringing sound can come from a fixed coil that isn't kept still with enough epoxy. Hope this helps.

If there was a popping noise of any kind when the tv screen went black there's a high possibility that one of the fuses in the tv popped and there is no power to the tv. It could also just be the outlet itself and try plugging the tv to different working outlets.

It sounds like you might get lucky and have blown the in-line fuse. By lucky, I mean, it could be worse, but you need to open the tv and check for the "white/Slow Blow" fuse that connects to the power plug of the tv.


Hope this helps :)

If your TV makes ANY noise at all while trying to power up(turn on) then your A/C FUSE IS GOOD.
Relay makes a clicking niose when TV is turned on.
Any led that lights up while trying to power up set>>A/C fuse will be good!!!

Your power supply has failed; have it replaced

Hey Jim, The high voltage protection circuit has gone out on the D-board and will need to be replaced. The fuse to the power supply is probably fine. A good repair tech shouldn't charge over $125 for this and it only takes a couple of hours. Let me know if I can be of further assistance.
