I managed to fix my LED projector, the device suddenly began an On/Off cycle after a few minutes being turned on, with less than 7000hrs on the lamp I suspected there was something else going on but didn’t know what, to my surprise after finding the post, it turned out to be a burned Inductor.
Got it from mouser.mx “IHLP5050FDER1R0M8A” for about 7 USD, removed it from the old Inductor from PCB and soldered the new one.
To my surprise everything works great now.
On a side note, I noticed that the projector heats less than before, I cannot tell why however I noticed that the fans run now smoothly without having to go manually to set the energy mode to Minimum again.
