    Lg42lh3000 Remote

    Hi,
    the led in the remote is constantly blinking (when viewed through a mobile phone camera) even when no keys are being pressed. I have separated the keypad from the pcb but the led continues to flash.
    Can anyone please advise what is causing this?

    Thanks,

    Clean the PCB with 99% IPA and a toothbrush, then test again without the keypad. See what gives…
    Upload some pics using the attachment function, so we can see something.

      Thanks for your reply.
      I had actually already cleaned the PCB with IPA but this had not solved the problem.
      So I was about to give it another go when I noticed that the one of the metal directional button contacts, which are held in place on the PCB by a thin plastic membrane, had moved slightly out of position. So I repositioned the button contact, cleaned the board with IPA again and the constant led blinking stopped. The remote now works OK.
      Thanks again for your help.
