When I turn on the aircon the inside unit works well i 1-2 minutes. Then the 2 green lights are turned off and the top green light starts to blink. Can it be the water tube that is blocked so the unit can not get rid of the water?

The Mitsubishi units have to be reset by turning off the indoor units by switching the remote or thermostat to off. Then turn off the breaker to the outside unit(s). After 30 seconds,turn on the breaker and then you can turn on the remote for cool. If no lights come on on the inside units, most likely you have blown a fuse soldered on the main PC board. At this point, call your technician. A goos tech will be able to wire in an in-line fuse holder so if it should happen again, you can easily replace the fuse. If you do see a light or two come on at the indoor unit but the outdoor unit does not start after 3 or 4 minutes, sounds like you will need to call a technician. Most likely you have a blown fuse on the main PC board of the outside unit. It is not an easy one to replace. Good Luck!

Green blinks indicate communication to outdoor, but red light indicates communication problem. Check PCB.
