1. Self-diagnosis error 4-4, check for open F9A06 part # 283P128050 on the Power PCB. 2. Self-diagnosis error 4-4, check for proper seating of the DVI cable between the FMT PCB and the DMD (Light Engine). It may be necessary to disconnect and reconnect this cable to insure proper connection. 3.

Hi Sally Jo, Unit powers on and works properly for a while then shuts off with a red lamp LED (lamp error). Suspect bad lamp part # 915P020010 2. Lamp enable line at J14 pin 6 does not switch to 5 volts after turn on, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977010 3. At power on the lamp turns on and off three times and then the unit shuts down with a red lamp LED (lamp error). Replace the Light Engine part # 939P977010 4. Check for 12-volts DC at J-9 connector pin 4 on the Engine Driver PCB, if missing check for an open F9A09 on the Power PCB, if it is open replace F9A09 part # 283P127060 and the Light Engine part # 939P977010 5. Lamp enable line at connector J14 pin 6 on the Engine Driver PCB switches to 5 volts after turn on but does not go back to 0-volts (low) after 5 seconds, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977010 6. Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if missing replace the Power PCB part # 934C148001. Hope this helps!

fixityrsel is wrong.
1 The "Airflow message"is just a bad connection and very easily solved.Mitsubishi has a service bulletin out and will cover the repair for free. Your set may not even have the defective connectors.
Your set was manufactured in 2004..Call any authorized Mitsubishi
Capacitors are very easy to find! Any (105 degree) PC mount 3300uf@ 16VDC will work fine..and not bulge again..Higher Working voltage than the stock 10 VDC is what caused the problem with the caps.
Mouser electronic is one of hundreds of suppliers for those caps
Order online if you know for sure they are bad in your set.
