I have just acquired a broken Samsung PN50B860Y2F that is clicking on and off when the TV is turned on. When plugged in the red standby light is steady. When I use the remote to turn the TV on, the TV just click on and off. The previous owner told me that he had purchased a new power supply and replaced it but the clicking continues. I have researched the problem and have viewed couple of youtube videos on how to pin point the problem by disconnecting the wires to the the main board, the y-sustain board, the x-sustain board, and the logic board that were connected to the power supply and turn on the TV to see if it clicks. I initially plugged in the logic board to the power supply and there was no clicking. I unplugged the power cord and waited 5 minutes. Then plug the cable from the main board to power supply. Plug in the power cord to the wall plug and turned on the TV. The TV starts clicking. I then unplugged the TV, wait 5 minutes, unplugged the main board and plugged in the X and Y sustain boards to the power supply. Then plugged the TV back in and turned on with the remote. No clicking. So I believe I have pin pointed to a high certainty that the source of the problem comes from the main board.
Looking at the main board, there is nothing that I can see with the naked eye that tells me that a component has gone bad. My question is: with these kind of boards, is it worth it for a person who has no knowledge about electronics to try to figure out the problem or should I just get a board from say Ebay to replace and be done with it? I am a type of person who likes to learn what can be taught and attempt to tinker and repair if I could. My soldering skill is a little better than normal amateurs (I have replaced capacitors with success prior) but not as good compared to trained electronic professionals.
Your opinion is greatly appreciated.
