Fan 3 was making noise, and today stopped working. TV says check fan3 and auto tunr off after only a few minutes on.
First thing would be to remove cover and look at fans, dirt or dust on one will lock it up.
Google the model number with Parts and a good idea if one or more are identical is replace or even swap them.
The lamp fan and main fan should be easy to see with back removed and are plugged in so if an exact replacement is obtained a few screws and plug and back in business.

Remove your new bulb and examine the connector carefully. The inexpensive replacement bulbs tend to arc and ruin your $700 ballast; sad to say. If everything looks good, make sure the interlock switch on the bulb cover opening is engaging. It won't fire up if it thinks that door is open.

all 3 lights blinking means lamp has a fault the service manual says replace the lamp. If you need the service training manual for that model let me know and I will post the link as the training manual has excellent trouble shooting breakdowns for that model DLP

You will have to pull out the light engine. That will consist of 4 or more screws and disconnecting some plugs. The the whole unit slides out where you can get to the fan housing.
Unless you're mechanically inclined, you should not try it as you could damage the assembly.
I don't know the part number off hand and some of those have newer part numbers as replacement for the original. Just do a google search to come up with a part number.

This sounds to me like one of two possibilities. First, check your ballast. If you're going through bulbs faster than you think you ought to be, you may have a ballast that is overloading. Its the 3" x 8" circuit board that connects directly to the bulb. They are plentiful and often cheap. Thats what I'd try first. If that doesnt' do it, I would invest in a new power supply board. That the board that the tv power cable hooks directly in to. This should give you a start, Comment back if you still need further help. Good luck.
