studio spot lamp auto on

Hi all:
Got a prob wondering if anyone else has the same & what I can do to fix this.

SS #1 I found this fixture's lamp on one day & went to check it out & noticed it had been on all night. I had to turn the fixture off manually to avoid any further damages. I shutdown my fixtures every night & have never had this problem before why is it turning on byitself?:confused: all the other motor's pan, tilt, etc are off except lamp. the data is also shut off to avoid resetting.

SS #2 Fixture tests fine for about 5 minutes & then the LED fades in & out & light resets again. It sometimes works in the show like moving to programmed scenes, but no light is on, this only happens for half the time I imagine it is doing the same thing like in the test mode. it suddenly drops power & doesnt come back on.
