Q: My image flashes in and out and/or it is flagging at the top

A: You may be running too long of a cable and need a distribution amp to boost the signal to the projector. Video can be sent via S-video cable without a distribution amp about 100 feet at the most using good quality shielded cable. RGB cable can be sent without a distribution amp about 25-30 feet using an HD15 pin cable. If you use shielded coaxial 5-wire cable it can be run up to 60 feet without any problems You should also check your lamp life meter - you may need a new lamp.
