Help..... Left half of screen dark.. Can still see image through darkness a little.. wont let me change most settings now. Lamp is under 300 hours. I do know how to change components and solder if its something on the board. took it apart and tried to test voltage levels on parts of the board and accidently blew a fuse but took care of that. Actually more than half the screen now. happened overnight, not a gradual problem.

Re: Help.....

Hi there.

This is definetly the light tunnel issue. After searching and a million phonecalls, I tracked down a place that you can buy the light tunel for $41 on their own and simply put that in, making the projector good as new.
I Have the phone number of the place and also the link to the forum giving you fully pictured diagrams of how to change the light tunnel, and also I have a service manual if anyone would like it to be sent to them.

Re: Help.....

Please read other posts concerning this problem. It's the light tunnel that's the problem and certainly not the lamp.

X2 OHP mounted on ceiling fixture. Image is dark on right side

Yes it will have to come off the ceiling. It sounds like the light tunnel has collasped. This is located under the colorwheel. If you can get a new tunnel , be careful removing the colorwheel so no segments break off of it...make sure the new tunnel is pushed against the "lip" before screwing the tunnel clip back into place.

Have your projector professionally cleaned. It is dust in the inside optics. You should not attempt unless you are very skilled. if you are going to do this yourself have a lot of compressed air on hand.

Hi Striker 53

Yes , a flickering image and dimming is a very clear indication that the lamp is going.

To make 100% sure and to give you some peace of mind - take out the lamp and you will either see vein like looking marks on the lamp or discolouration or even that there is a bubble at the end of the lamp's shaft.

Do keep in mind that a lamp normally gets a rating of say 2000-3000 hours , but that is only a estimate from the manufacturers factory. I've had lamps that had less than 300 hours on them , that needed replacement.

Once you replaced the lamp , remember to reset the lamp timer.
