Have TV Questions? Ask a TV Technician
Hello, My name is ***** ***** I'll be assisting you. I'm sorry you're having problems.
We are not able to see the question that brought you here- that's simply a link and you land on a new page. That being said, the clicking on a Samsung is a bad Mainboard- the caps and power board give different symptoms. The service bulletin from Samsung states that clicking after the set was plugged in, indicates a faulty mainboard (not power board), so you would want to replace your mainboard for this issue.
Also to obtain the correct mainboard, make sure you pull the part number off of the board in your set to search- as Samsung can change the part number even within the same model number.
If you want to see if the power board fires up, disconnect the mainboard, and make a little jumper then tough the PS-ON pin on the power board to ground.
If you need further assistance let me know. Before you go, PLEASE DO click at least a 3 STAR RATING, at the top of your screen. That is how I am credited for my efforts by the site. You can follow up any time as needed at no additional cost.
