I just received my new JVC DLA-X500R projector and installed it the same day. I was able to play DVDs but when I went to play Blu-ray DVDs, I just got a black screen. I tried to apply the firmware three times with various cables that I thought should work. Thanks to other posts, I was able to purchase a 9 pin null modem cable and apply the firmware update using an older model PC that had the 9 pin com port. I gave up trying to apply the update with a 9 pin to USB as it kept failing. No where in the documentation or on line with support did I see a null modem cable mentioned. Thanks again to the posts the pointed me in the right direction.
