The primary cause of LCD TV and monitor failure *may*be faulty capacitors. If they appear bulged on top, then they need to be replaced. all capacitors are good not physical damage. the \Tv is turning on now no clicking sound, but it stays blank no pictures. after replacing the board LJ41-06613A. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad. A capacitors job is to block dc, allow ac currents to … capacitors can also look fine and fail also . Fault Symptoms Arising from Bad, Leaking or Blown Capacitors The diagnosis for any faulty apparatus will be different in each case. i have a samsung plasma tv model; ps42b430p2w that was making a clicking sound and not powering on. I have a Capacitor/ESR meter. - Vizio Television. so i change the bad that i assume was bad . Samsung has set up a Web site to deal with the proposed settlement of a class action lawsuit applying to certain older TVs plagued by a faulty capacitor. what can i do If you provide us with more details about what model your TV is as well as what the symptoms are, we might find more information for you. The bad capacitors have a much lower capacitance than their specified value. I've looked at the circuit boards and can't seem to tell if any capacitors have gone bad. Obviously the circuit was designed for approximately the full value, so it isn’t going to work correctly at 1/10 the capacitance. Yep, I've seen it, and it was only by the way the symptoms seemed typical to that kind of problem and dumb luck that we tried wiring another in parallel to the suspected one that we discovered it. How can I check to see which one is bad? I think most of the time this happens it goes unfixed unless you have a good in-circuit capacitor tester tool. Well, their electrolyte dried up and leaked, so what do you expect? A quick check of the fuse should be the first step, but if the fuse is good, then the problem lies elsewhere.
