Benq LK970 projector has red "light" light on?

[cameron paterson]

So my Benq LK970 projector has been giving me trouble turning it on. Sometimes when I push power the red "light" light turns on then it shuts off. But then if I unplug it then plug it back in it usually starts up and never turns off during the movie. For the last few days it has been starting up fine the first try without unplugging and plugging it back in. Is this a laser problem or something else? If you guys could please give me your thoughts on this that would be great!
Thank you for your time!

Read your manual! On page 45 it lists the causes of the red light coming on. It has a lot of causes. My hunch though is that the cooling fan is failing and not getting up to speed quick enough the first turn on, possibly because a bearing is starting to cease up. I don't see that the unit has a diagnostic port, so it may well need the attention of a tech experienced in with these units. Its fault coding system seems elementary in the extreme for such a costly unit.

Thank you for that. Another problem thats happening is when I pull up the menu it will not allow me to use the first two parts of the menu and the last part of the menu. (The "picture" and the "display", and the last one "information"). The "installation", "system setup basic" and "system setup advanced" all work. What could be causing this?
