Hello Steve, hi, the power supply detected an overload, thats the reason on the 3 LED light. most likely your DLP has power supply problems. I suggest you bring it to a DLP dealer and have it checked.

Could possibly be a faulty lamp. Did you change the lamp or just the burner? It could also be a grounding issue with the optocouplers when the lamp is lit.

I got the same projector and have had to take it apart a few times, they are not to hard to open

There are 5 (not inc the projector cover screw) screws to remove from the bottom of the projector (A long neck philps screw driver will be needed). Once these are removed The top will be loose apart from catching midle of the front and at the back, This is down to the top being clipped in the middle.

Remove the grey panel round the connectors, one sreew and the 2 plug fixing nuts around the DVI Port. Once these are removed pull the panel away from the projector, pulling from the midle of the panel as its cliped to the side. Once remove lift the top of the projector roateing it around the front

Hope this helps
