    One of our 4 yr old Able 2.5w RGB systems has a 500mw red diode that was slow to come on for a while and then gradually just quit showing up. Opened the unit up and was hoping for a bad connection. Sprayed and reseated everything I could get to, including the brightness trim pot on the back but no...

    Does anyone know of a way to convert an ILDA frame to a DXF file (or similar vector file) so that it can be edited externally? Can't seem to find anything from googling around and searching the forum. Thanks!

    Hello, Does somebody know how to remove the diodes from the NUBM08 block? I have read that it is necessary to heat the block. But how high should the temperature be? I removed the PCB from the diodes but cannot get the diodes out of the block. Thanks Joachim
