Screen pulses/flickers

[nueskewl]

Recently our HLP4663w started shutting itself off and displayed three flashing lights on the power button on the t.v. We replaced the bulb and the shut downs have stopped but the tv picture pulses when it's on. This happens on both component inputs. Also component #2 seems to be much brighter than component #1. Does the t.v. need to be calibrated or have a factory reset or is something else about to go?

You can try using your original remote and see the default settings and reset back.
