    Hi All,

    I was taking apart a VCR I found in the trash in my apartment building. While soldering a bunch of pots and momentary push buttons for my junk bin, I noticed a black plastic housing that contained a LED. I popped that off and found a violet/purple colored LED that was vertically mounted on the PCB. I am curious what this would of been used for? I already grabbed the IR leds that were front mounted.

    I didn't want to plug it on in case it was mildly dangerous :)

    Hello,

    Can you post a picture of the "led" ?
    How many pins has this "led" .
    It can be that it has been used to detect the tape in some kind.

    Greetings,
    Bertus

    Bertus is correct - it is the cassette detector. The circular hole in the bottom of a VCR cassette fits over it when loaded.

    I will post a pic tonight. Its a two pin Led, 5mm by the looks of it. I didn't look at the mechanical assembly on top but I suspect I will find another part to receive the presumably IR signal.
