    circuit diagram
    I try to repair my 3M MP7750 projector. on the lmap power supply board there are two resistors which look a litle carbonized so that teh values are not readable any more R06 is 6?8 or 8?9 And the value of R07 I can't read anything. Measurement with multimeter in the mounted state shows 130kOhm.
    I suppose both are the same and the value is 6.8 Ohm. What do you think. The STR G6153 I have replaced aleady. But before I reassemble everything I would like to replace these resistors as well. Wht do you think?
    Does somebody have a circuit diagram?

    Need a part
    One of the Lens(I guess it is a lens. It is square and plastic) inside the projector looks like it got to hot and has turned brown. It makes the picture have a brown tint.Can I just buy a new lens?
