Check for popped or raised tops on caps in power supply. also try unplugging set for 5 minutes and resetting it. How about does your color wheel spin up? if your color wheel don't startup then your tv will also shut down. also check all fans they all should be running at turn on. if all fails i would say its your light engine.

Mitsubishi tv keeps turning off.

Hello there please check the following in your tv;

Reset the component settings. Most problems with Mitsubishi projection televisions can be resolved by resetting the television to factory settings

If this does not work then a full system reset should be performed on the control panel by pressing the System Reset button. The television will turn off and the green LED light will flash quickly for a minute. When the light stops flashing, the TV will turn on.

If that still doesn't work, then the projection lamp might need replacing and here is how to do that;

Ensure that the bulb is completely cooled and the television is unplugged. Use a Phillips-head screwdriver to remove the lamp compartment cover. Unscrew the lamp cartridge on the rear of the television. As opposed to the cover door, these screws do not actually come out of their chamber and simply loosen the lamp assembly. Remove the old cartridge and insert the new one. Secure the lamp with screws, then replace the cover and screw in tightly.

Please note that, Finger oils can cause the lamp to malfunction.

Projection lamps are powered by mercury. Wash hands thoroughly after replacing the projection bulb.

AKAI Rear Projection 46"TV has a blank picture with sound only


Is it a CRT or a DLP/LCD projector? If not a CRT, a worn-out projection lamp can cause this symptom. When it is a DLP projector, a faulty Colour Wheel sensor can be the additional problem. If it is a CRT projection unit the High Voltage and deflection circuit must be examined...

Please tell me more about your unit...
