    21SF8XEL 21" CRT TV ripped pads, PCB (kd -331 (v1.0) sh12144)

    Hello
    someone forced the STR (FSCQ1265RT) out and ripped the pads off
    now I need to reconstruct the tracks but I dont know how it will go (no prior pics before the damage)
    Attached the affected area pic, pic 2 is the best i could found online for the same area Click image for larger version

    the pins from 1 to 5 are for the STR
    any help is appreciated
    Thanks

    This schematic uses the same FSCQ1265RT ic (page 17) so you should be able to compare, I would need a picture of that complete area to do a proper trace. See if pin 4 trace connects to the optocoupler, here is my best guess

      yes indeed i agree with your assumption
      i have shared a pic showing where is the opticoupler
      now i need first to check that STR, see if it might be still good or bad, i know it is impossible to know for sure on cold testing but at least pass it
      can you tell me how to test it for that?
      thanks a lot for your help and time Click image for larger version

        The TV worked again directly after a correct trace reconstructions based on your suggestion, will let you know if there are any problems, so far so good, thank you very much

          Now i am at the original problem the customer was complaining from, which is the tv works sometimes and then goto standby , then might work again by itself and so on randomly,
          what do you think specially that i did not find any blown nor a swollen cap
