Unfortunately that is 2 different errors... One being easily fixed. The 5 blinking power LED means its time to replace the Lamp, thats the easiest one to fix.
The blinking ready light means a "Fan 3 error". There is no reference on what that could be. It could be as simple as cleaning the air filter, or as complicated as replacing one of the fan units. You will need to contact Vivitek to know for sure:
