We have an Akai rear projection DLP 61", turned it on this morning and a loud fan whirring sound is on. Anyone have this problem?

This set with Akai is actually made by Samsung (they own and use the Akai name).

If lamp light etc and you have heard a cracking sound it may be the color wheel.

You can remove the lamp and look where it faces--look and the wheel can be seen----is it shattered or missing plastic pieces?

The wheel commonly fails in this fashion and is turning at over 12,000 rpm. The set will detect if the wheel is stopped or moving too slow and just what you describe will happen.

Wheel is widely available and You Tube has video instructions for replacing them by model number.

Questions?

Sounds like a classic color wheel failure.

it sounds like the lamp or fan. do you feel airflow? Unplug the set and wait. When you plug it up is the whinning imedate. the color wheel generally is the first thing to come on. If it dosent reach speed it will shut down

Color wheel sounds like it needs replacement. The set will often shut down when the color wheel gets bad and wont power up.

turn on video mode if loud humming still occurred replace filter capacitor on audio section from your tv ckt board.

Ballast board is what turns Lamp on and CK your Fans if Lamp Fan is defective TV willnot come on.

Check the link below - sounds like you have a bad color wheel.

probably bad color wheel. not an easy repair. some of the rca dlp required the light engine be
pulled out to replace color wheel.

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.

Sounds like you have a noisy color wheel. Very common on all Samsung DLP`s. The part # is BP96-00250A for model HLN5065W.
