20 Most Recent Yamaha LPX-510 Multimedia Projector Questions & Answers

perhaps the mainboard is bad

Welcome to the disapointing world of LCD projection. Your blue device is dying and thus allowing the green to come through instead of combining for white. I suggest buying a dlp product they are immune to this color decay problem. Good luck

VGA cable or S-Video if your projector has a S-video port

Hope this helps

I just saw your post & today is Mar 19,2008. I had the same problem and was pissed until I noticed YAMAHA has a good warranty, so I sent it back and they put in NEW OPTICS that are non-organic (I guess the original ones were organic) NOW my picture is much better than when it was new. This picture is so clear I can not believe it.

no a boat anchor. the power supply inside is bad, (1st choice) we test it.

Try to replace C4 capacitor on relay board in power supply area
