I have a call on this projector later in the week...my first one. Downloaded the service manual, thanks to Toshiba's kindness on providing this information to us.. >From looking at the troubleshooting guide, possibilities are the lamp(customer >says they replaced), Controller ECA(510-1530-xx) or optical engine (505-1181) First, is there any way to determine which is at fault, before purchasing the wrong part? Secondly, where do these parts come from? I checked Tritronics, they only list the lamp....very expensive lamp.. Any help appreciated.. Thank you.
