I can not pick the right part for you but those part sites do that all the time.
Our HL-T6187sx/xaa has white dots and they are multiplying! From what I've read this isn't on the recall list. So, please help me buy the correct part(s) from a reputable source. We've already replaced the red LED/Chip on this set so I'm hoping this is about the same amount of trouble. Links to reliable DIY instructions would be great too.
