To correct this problem the optical engine in the TV must be replaced. However, the repair cost is quite high: The Mitsubishi replacement retails for $1082.40, plus shipping, tax, and labor. Usually labor is in the $200-300 range (in my area). If needed, the part number for the optical engine is: 938P075040. You may be able to find less expensive optical engines on the internet, but these engines could be a gamble, so please use caution if shopping for a lower price.
