Title: sanyo 3lcd projector plc-xu75
Post by: kokodin on April 15, 2019, 08:21:48 pm
Hello, i would like to ask you for help, mostly in finding a place where i could discuss the issue with my projector.
Problem with the device is not electronical, it is more of an optical one. Therefore i am more interested in informations if there is any forum or other form of community that helps with repairs of multimedia projectors and similar equipment. However if you know what went wrong with it i would be gald for any information that can help.

Device in question is Sanyo plc-xu75 3lcd projector (2500 lumen 1024x768 with only analog inputs)
I rescued this projector 2 years ago for 10$ out of a truck with broken computer equipment going to a landfield. I bought 5 projectors and 4 of them (including this one) were fully restored to working order with little to no effort. However this particular projector have color issue, which manifests as left side of the screen being slightly tinted red and right side is slightly tinted cyan. It is mostly visable on white images or when entire screen is moving from side to side, eg. paning panorama shots . To make things even more frustrating for me, lamp i have is an oryginal bulb in non oryginal module. And i did go trough entire service manual many times, doing all provided adjustments, which should fix color issues. Nothing helped. I even replaced entire optical unit part by part, everything expect the bulb. And the bulb itself was bought new, because projector was missing one from the start. So the lamp should not be the problem either, unless i was very unlucky.

If you have experience in fixing sanyo projectors or you know someone who has, please let me know.
thanks

I'm not an expert in this but I think the lamp is broken, If you're having the color issue it's probably the bulb issue.
