New member Username: RchartraPost Number: 1 Registered: Jun-09 | The red light on my hd 52z585 red is backwards and I cannot adjust it back through the service menu. Is it a mirror problem, lamp or just ditch the T.V. Please help!!! |

This link shows you the schematic of the LCOS RPTV light engine; it shows how the light passes thru the color chips: http://www.oerlikon.com/ecomaXL/index.php?site=OPTICS_EN_lcos_rptv_light_engine I also found that if one of the LCOS color chips has a bad driver then this could also cause the red background. This link shows you the color chip driver: http://tfcg.elis.ugent.be/projects/xgv0901.pdf If you want to learn more about the LCOS projection TV, check out: http://electronics.howstuffworks.com/projection-tv2.htm Good luck Robert. |
