I have a factory sealed and shipped PK-L2312UP lamp (they sent the wrong one). Has anybody used this lamp (replacement for the RS66) in the RS60? They did send the correct lamp but I still have the PK-L2312UP. The factory has replaced the motherboard and firmware to fix short lamp life issues and freezing. The fan runs faster than it did in the old motherboard/firmware combo if this makes a difference? Thanks!
