    Re: SAMSUNG PS42D4S, won't turn on, no standby

    Hello again guys. I left this TV aside as I spent time on some others, gaining some knowledge and now coming back. Changed the IC, nothing found on the rest of the circuit afterwards.
    I now plug the TV and I see the relay is not even clicking. Based on the schematic provided, I see fuse F5 before the relay is burnt, MM shows open, while the rest same fuses on the circuit seem fine/beeping. I m thinking if the chip got burnt but nearby diodes seem fine and the fuse is also burnt, if there is definitely something else wrong with this board that caused these symptoms or maybe just a lightning or high voltage from the network.

      Hi guys, I’m back here my friend give me her tv, that doesn’t turn on and no standby red led. When u plug in the cord the red led of one two second is on, then turn off. If you push the power button or the remote the red led blinks but nothing happen. I give u some photo with voltage, don’t look the fuse….because I blow it for mistake nd I dint have the right replace so I just put it for test the tv. The standby voltage should be 11,88 volt on the diode, but I have 13 volts. I put in the photo the different volts I test and there are someone negative…I don’t know if it s normal. On...

      Zombie Samsung UN55NU6900F dead / no standby voltage - randomly came to life after hours of troubleshooting then died
      by tvguy12012012120
      This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.

      Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today....

      LED TV Samsung The Frame 55 inch QE55LS03RAU Standby Light only
      by ChristianBr01
      Hello everyone,
      I got a Samsung The Frame 55 inch TV for free from uncle cause it is not turning on anymore. I am in the second year of training as an electrician so I have knowledge already but I am far away from to be a pro.
      The TV has Standby but ist not turning on. A Friend of mine owns a 50 inch Frame TV so I checked the One Connect Box and the One Connect Cable there. Both are good and working normally. I have opened the TV case and measured some voltages on the Board.
      What I already found is that the 12.8V are not an the connector to the main board connector to the power...
