I have a Sanyo PLCXU20B, which is quite old. For the last 6 months I have been using this to play both Region 1 and 2 DVDs with no problem. The projector is connected to a Pioneer R2 player which is chipped to play R1 discs, and it is connected with an S-Video lead However, suddenly, the projector will not show images on my Region 1 disc - I simply get a blue background screen as if the DVD was not on. (Sound still plays though). There is no problem with my R2 discs (picture is fine), and my region 1 discs play fine when the DVD is connected to my TV. I have also checked the wiring to the projector, and there is no problem. Does anybody have any idea what the problem might be, and, more importantly what I can do to fix it ? Many thanks for any assistance.
