You need to replace your Lamp. The 6-6 code indicates "Lamp not installed", "Lamp did not fire", or "Ballast did not fire". The set attempts to start up three times, then the Red LED (Lamp light) shows up. This is all common with a failed lamp. These lamps run hot and typically run between 2-3 years and are consumable components that are designed to fail. The solution is to replace the Lamp in your set with the correct OEM lamp. Try to refrain from buying the $40-$50 lamps on Amazon or from Pureglare as they are NOT rated by Mitsubishi for these sets, and tend to run for a few months at most if they even work out of the box. The link below is to the correct Lamp for your set:

ok just ordered from site you suggested. odd course of error code changes. hope this works. lamp doesnt look burnt but manufacure date was 2008
The lamps typically won't look any different when they are bad, as they are gas charged and can lose their internal gases.
