This is most likely your Digital Processor Module. So far most all makes are selling them as a complete Light Engine Assembly which includes the light tunnel, digital module and color wheel. They are rather expensive, some are in the $800.00 range, a few more dollars and you have a new set.

Sure, you can test by Use the screwdriver and remove the protective cover that conceals the ballast.

Observe the ballast before proceeding. If oil is leaking from the ballast, stop here and remove the ballast. Leaking oil indicates that the ballast is damaged beyond any doubt as the internal seal has been ruptured by excessive heat.

Test the high voltage side for continuity between the wires going to the ballast tombstones. There will be either one or two wires going to each tombstone fixture. Regardless of the number of wires, the colors will be the following: Blue or yellow are the power wires and white is the common or neutral wire. this could differ in many models.

Turn the Volt Ohmmeter to "ohms" and touch the ends of the two probes together. The meter should show continuity or a direct short. Touch the probes of the meter to one of the white wires and one of the colored, blue or yellow, or any wires that comes from the ballast. This should show a short or continuous circuit. If it does not, the ballast is bad and should be replaced.

I would try replacing the entire ballast. Make sure that the lamp switch is good too. 3 blinks usually indicates an open lamp door.
