You may still have an issue with the color wheel. That or the ballast is bad. I don't think it's the lamp if you've just purchased a new one. It's possible that you've installed the color wheel wrong, or that the color wheel is defective.

TV has video for about 10 seconds after turning on and then about 5 seconds later audio goes and TV goes out - what is the problem?


Possible bad lamp, color wheel, or ballast.

Remove lamp and look to see if glass pillar in middle is straight and not bent from heat.

Color wheel faces the lamp--usually when or before fails you get a fan like or high pitched sound from it. Look to see it is not missing segments or shattered.

The picture come on then goes black and then the television turns off. I thought it might be a bulb problem (4 years old). So I bought a new bulb, seemed to work and then began to go black again with all 3...


when the colorwheels start to go bad this is the symtom that shows up. try this listen carefully to the rear of the tv near the lamp door. as you turn off the tv if you hear a slight grinding noise as the colorwheel slows down that means the bearings inside the colorwheel are dry and you will need to replace the colorwheel.

Lamp replacement issue infocus in24+


either the lamp's seams aren't taped over with foil tape to prevent the premature shutdown due to the heat sensors being triggered, or the fan under the the colorwheel has stopped, maybe due to a piece of lamp from a previous lamp explosion being stuck in it, or the power supply/ballast is bad, or the eca on the engine itself is bad. The lamp is the easiest to try first. There should be foil tape over the seam on the side of the lamp you can't see when it is installed. If this doesn't work, take the front bezel off amd get where you can see the fan under the colorwheel and tunnel and power the unit up and see if the fan comes on. If it does thenthe eca on the engine or the power supply ballast is most likely bad and these are major repairs.

When I try to cut on the TV all 3 indicator light start to blink.


listen to the tv from the rear you should hear a slight wind up of the colorwheel just after the power button is pressed. after that the lamp ballast should attempt to start the lamp . if the lamp is bad you will hear a buzzing and see no light coming from the lamp door. if you dont hear that winding up of the colorwheel its bad and needs to be replaced

Wont light up


the colorwheel needs replacing. if the colorwheel won't spin, the lamp won't light. if you hear a high-pitched whir, the colorwheel works, which means there is a power supply issue. there is a fix for that, but you have to be good at soldering. if you are give it a try: http://www.infocus.com/service/asc/communications/tech_notes/2006/09/tn495g.pdf
