SOURCE: won't power up
This model has had problems with the keyboard buttons on the front panel,causing them not to work and canceling out the remote operation. To verify this,you need to remove the front panel so you can access the connector on the keyboard pc board and unplug the connector.After doing this,see if the remote control is able to turn on the tv (wait for it to power up because with the connector off, the green power light will be disconnected and will not light up when the tv is on) If the tv works, than you will need to change the ten individual switches on the board - part# 432P089010 (or just use the remote only)
SOURCE: no cooling after power out, indicator lights pattern not in manual
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!

hold the menu bottun for 10 seconds

SOURCE: green power light will not stop flashing and tv will not turn on or off
You need to replace the 1000uf capacitors on the DM board thats the classic symptom of the DM caps being bad the light continues to blink repeatedly. If you need more info on the repair let me know.
