jfenwickar,
There's a number of things that may be causing that error. There's no specific solution for all three blinking.

I have a HL-R6156W that has been great until last week. It no longer successfully turns on.
It powers up, the lamp light for 3-5 seconds with the lamp indicator light flashing, then the lamp shuts off, then after another 5-7 seconds it power cycles on its own.
It does this 3 times then fails with all three lights on the front power button lit.
I have replaced and reseated the lamp. I have checked the fans, all three are working.
What does the 'all three lights on' failure indicate? Does anyone know?
