    Daewoo DF-4501P DVD/VCR No disc?

    Friend of the Bro inlaw asked me to take a look so I said yes as he said it was a good one

    Anyway, its not, but would still like to get it going for him.

    When inserting a disc it attempts to spin then says NO on the screen.

    It does the same without a disc too so I know its not even attempting to read a disc when inserted.

    There are 2 pots that can be adjusted on the laser housing, i have adjusted these and it still does the same, normally when adjusting pots on lasers it reacts differently, like spinning faster and stuff but this just does the same thing over and over.

    I am thinking it has a dead laser (although it is still illuminating) but thought i would stick some pics up on here in case anyone can help if its not.

    The reason I think dead laser is because he says he plays copies on it.

    Just to add, it doesnt play CDs either, so now I am thinking the laser may be ok?

      Bad laser would cause no discs to be read.
      I'd check PSU outputs and see if they are all there and stable.

        Will check them now. Managed to find the service manual, thought it would be hard to find for a piece of poo like this.

          All voltages present and correct.

          Is there a way to test the laser?

          Or motor.

            The laser will lase, i.e. glow red, if it is working.
            The motor will move, if it is working.

              The laser lights up fine.

              The motor attempts to spin disc too.

              So then if they are both working what are my other options?, I know you're more into tvs but any help would be great as usual.

                Reseat all connectors going to the DVD head?

                  Tried all that. Not sure about the vcr bit because i havent got any tapes.

                  I know the head spins up and thats it?

                  Why he wants it fixing I dont know, can get new dvd players for £15ish.

                    I recently saw one in the charity shop for £10.
                    I would guess perhaps the read portion of the laser is not working.

                      Gave up, not worth messing about with. Thanks Tom.
