Question about Samsung HC-R4755W 47" HDTV
MODEL PICTURED IS REAR PROJECTION WITH PICTURE TUBES.
IF IT HAS NOT BEEN "SERVICED" FOR SOME TIME TRY THIS:
WITH SET UNPLUGGED REMOVE BACK COVER---LOOK UP AND LOCATE THE THREE LARGE ROUND BLACK LENS--they can be cleaned with either a lens cloth or a paper towel with glass cleaner sprayed on it.
They are the light source for your picture and if even moderately dusty will make picture duller and darker than it once was.
Cleaning, depending on how dusty a environment you have the set in, should be done once a year.
If this told you something you did not know rate this solution as very helpful as I do this here for free.
If you have any questions post a comment right here and I will assist you.
