Samsung HLN 4365WX Picture for 5 mins...then black

[VRich]

I replaced the bulb then color wheel. When TV is turned on, it will have perfect picture and sound for 5 minutes then black screen with sound. If TV turned off then on again, the picture is perfect again for 5 minutes...help!!!

I am having the same problem. Powers up normally, then screen goes black after a few minutes with no other symptoms. Press Power, unit powers down normally w/chime. Turn on again, picture is back, process repeats. When the screen goes black and you press Source, you do not see any source names -- just black.
