Question about Samsung HL-R5078W 50" HDTV

1 Answer

Failure to start, period.

Im no professional about T.V.'s period. but i own the Samsung HLR5078WX/XAA, and i watched a movie one night and fell asleep to it.
the next morning the tv was still on so i turned it off. The next time i proceeded to turn it on, It started like normal, made the beeping noise when the tv is initialized like it usually does(must be a samsung thing) and then just cuts out. and tries to (boot up) per say again. each cycle lasting about 3-5 seconds, the first cycle being the longest. and during this time i hear a louder than usual mid-high level whining sound that sounds like a fan but isnt. the sound winds up. , and stops as the tv ends the short cycle.
after about 6-8 cycles it finally turns off, and on the front, the lap(green), timer(green, and stadyby/heat(red) lights blink on and off.

    is the wheel replaceable and where would i find one? i took the lamp out and it looks fine. i see the fan that cools the lamp. and the sound seems like its coming from behind the fan and i have no clue how to get behind that.

The whining you hear is most likely the color wheel

Samsung hlr5078wx DLP tv. rumbling noise and shaky picture


This is a color wheel problem.
I would recommend to use professional help because you can make more damage to the optical engine. Not to mention index delay have to be re-adjusted in special service menu after repair is complete.
Regards.

Replacement color wheel for samsung 50'


I am having the exact same issue with the exact same TV. They no longer make that color wheel, so I am looking for a replacement part as well.

I am looking at the 01103A as well from here:
http://www.partstore.com/Part/Samsung/Samsung/BP9601103A/New.aspx?ModelMfgName=Samsung&ModelBrandName=Samsung&ModelNumber=HLR5078W

I think I might just order it, and if it doesn't work just return it.
