Hello. A friend of mine currently has an Optoma Ep739 and is he starting to have some problems with it starting up. He has replaced the bulb twice so we know its not the bulb. He took it apart and cleaned a part of it and it started to work for about 30 min and then it started to vibrate a bunch and then stopped. He then found a piece that was broken had it has 4 different colors on a motor. The party number he sent was 23.80Y19G012A5490050 and on the other side it says KYO. I was wondering if anyone know if this could be ordered directly through Optoma or if there was another place that sells parts for projectors. Thanks for your help.
