42 " plasma cutting out and making a loud clicking noise

It is a short circuit caused by some components and/or power capacitors. This may need assessment by a qualified service technician.

Defective and/or bulged capacitors on the power supply board.

I had the same problem. Fix it using the firmware update from Samsung Website. The customer support people are ****. They said it would caost be 500 to fix it.

Take the back off and try to isolate where the sound is coming from.

It sounds like your High Voltage transformer is arcing.
Sometimes it can be repaired if not it is an expensive fix.
If you can see in the back of it look for sparks inside but do
not remove the rear panel, you can get zapped with 40,000 volts!

Try resetting the TV. Unplug the AC, wait 1 minute then replug it. If not fixed, its requires service.

Hello gws51,

This sounds like a shutdown circuit proble, which is caused by the draw of excessive current. I would suggest that you have a qualified TV repair person look at you set and repair it.

I hope this helps

Thank you,

You MAY have some condensation in a high voltage path inside.
The noise might well be from leaking high voltage.

I recommend you let it climatize for a couple of days before trying it again, otherwise you may damage circuitry not normally involved with production of the HV.
