    Re: Bad transformer

    I found a transformer and soldered it to the board.Tv works great now.That little trans former had a pri.,sec.,and a aux.I changed F1 to a fast blow just for piece of mind,and i soldered a fuse holder on bottom of board .The fuse that was on the board was hard wired on,and it had no value on it. Think it acted like a jumper and killed mt trans coils. Thanks again every one.

      Re: Bad transformer

      You... found... a transformer? Just any old transformer? Put it in and it worked?
      That is like saying, my Ford's car engine is broken, but I found an engine from a Toyota, and it worked.
      Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
      For service manual, schematic, boardview (board view), datasheet, cad - use our search.

        Especially that, the so called transformer that he asked is not transformer but inductor and is part of the PFC Voltage booster circuits, he better check his DC voltage on the main cap to see what he is getting.

            Good day guys,

            I am looking for a schematic/ service manual for a Proscan 32LA30Q. I especially need the schematic for the PSU. Board number SBGD-200-3HP.
            Any help in this regard will be highly appreciated.
            Regards

              if the data sheets match on both transformers, shouldn't be any problems, NICE FIX.

                Wonder if you actually read the thread? It was NOT a TRANSFORMER
                it was an inductor.

                It is an old thread was only kicked as pretorif is looking for a schematic

                Anyone else reading this see above - pretorif looking for a schematic.
