Hello,
My father purchased the samsung flat screen listed in the title of the thread. It stopped working entirely and now clicks when trying to turn on. I've searched all the around the internet to find the solution to the problem because samsung themselves wouldn't give me a straight answer. Most of the problems seemed to be revolved around capacitors that have failed and just needed to be replaced. My father replaced the power supply board but that didn't remedy the problem. He plans on purchasing a new logic board in hopes that it would fix the problem. If there is a way to fix this...
