steve beseke, start with the basic major checkpoints. This is still one of the models that may suffer from Samsungs decision to use substandard capacitors on the power board. Your symptoms are pretty indicative of that. Post some good images of your power board etc. with your question. that way we can see what you see and we might be able to help you out further. Capacitor kits are readily available. Of course, it does not hurt to check the fuses for continuity.
I had the same problem with my TV and looked online to figure out what it could have been.. Turns out there was a class action lawsuit and my TV model was part of it. I contacted Samsung gave them my model # and the gentlemen said my TV was covered..they sent a Samsung tech the following day and he reapaired it on site..fast,very professional and free...
I also had this problem with my Samsung 50inch and I changed the power supply capacitors; did not fix.
Checked input voltage 120vac,but when I plugged in the connector the voltage dropped to 55vac.
Checked zener diode VX801S and resistor RX801S(750K) , both were bad. Changed and the problem was fixed.
My clicking issue is on my Samsung Plasma 50" when I switch it on, it comes on for a few moments then the picture disappears and it starts clicking.
Initially the picture would come back on after I messed about with the on off switch and remain on until I switched it off then the same thing would occur the following day when I switched it back on. Any suggestions on how to fix this issue?.
Had the same issue with 2012 model. Have a background in electronics so decided to have a look in the back (no test equipment). Noticed some discolouring around 2 pins on the power supply board that feeds the main processor board. Closer inspection showed that the plastic insulation between the pins had melted and they were shorting out (hence the continued on and off cycle). Cleaned the pins, used some silica set to insulate the pins, cleaned them and put panel back together. All working and keeping and eye on it re over heating.
