that means your lamp it is getting to the end of its life.
sometimes even if the lamp still good the TV will send you that message because that timer is closed to 5000 hours
What you can do is open the lamp door, closed again and the tv will ask you if you replaced it the lamp, and just say yes and that sign will go away
or just simple replace the lamp. 915P020010

Here is the link to the manual if you need it; http://www.hdtvsolutions.com/pdf/MIT_WD-52525_WD-62525_WD-52725_WD-62725_Manual.pdf page 97 states that the lamp is the problem -(the flashing green just means startup - page 11) 14 months sounds about right for a new lamp if you use it a lot - that would be an average of 5&1/2 hours a day if the lamp went to 4000 hrs - although these lamps are more dependable than normal lamps, they can still fail anytime especially if they have been touched on the glass by accident while installing or cleaning, or if the tv is often switched on and off. The fact that there was no message on screen may mean that the lamp has not gone past the warning trigger number of hours - sorry i haven't found what that value is. page 95&96 gives all instructions how to replace lamps and where to get spares - if the price seems bad then search around - prices often vary a lot on these lamps. It is a little disappointing that mitsubishi where not able to diagnose this - please let them know that their technical service is poor in the hope that they try harder. I hope this helps :) Hope this helps :)

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!
