this is really amazing... so many ppl having basically the same problem:
1/8 - 1/4" white dots that look like stars and rapidly multiply with a lesser number of black dots and, on a nice summer night, 1 or 2 dots that actually flicker.
I think I am gonna keep it like that, my GF and I think it's very romantic
Just kidding, I am really pised off:
Same crap here: HLS5086W PB02 purchased Dec 06 developed white dots about a month ago, now.... I have read in their entirety the 165 preceeding posts here, I took notes and at the end when I summarize everything it seems like....
If you have white dots your DLP chip (also called DMD panel) is bad
If you have a Version PB02 the part # you are to order would be 4719-001981
If you have a Version PB01 the part # you would order would be 4719-001968
Have some "Thermal Compound" handy when you do the job to replace an aparently iffy pad (Radio Shack has this compound generaly in stock).
Avoid touching the little mirrors with your fingers.
Avoid disconnecting the ribbon connector, (it gets tricky to put it back) instead fold it over
No re-alignment necessary if you don't mess with the adjustment screws and you shouldn't.
The places to get the replacement part are: Samsungparts.com, encompassparts.com, partstore.com (encompass right now is the chippest)
The replacement part is on backorder everywhere as of 5.5.09
Get your manuals and all bunch of documentation from this link posted by Pez (please read post #111 I am not allowed to post URL's) you will need mainly disassembly_reassembly_pdf.pdf
If you have more than 5000 hours on your lamp take this opportunity to replace it.
Check the hours by entering the Service Menu on your TV: Turn TV off, on the remote control press IN SEQUENCE (one by one) MUTE then 1 then 8 then 2 and finaly turn on your TV FROM THE RC. This will get you into the Service Menu and under OPTION the LAMP LIFE will display. STAY AWAY from FACTORY RESET or you will risk to erase all of your channel settings, lamp hours and ANY kind of customization you might have done to the set since you purchased it.
I cannot think of anything else right now but it would be great if people that have actually successfully replaced the part added to this synopsis by quoting it so all the info will continue staying together in one post rather than spreaded over 200 posts and whoever comes after this post will have an easier time understanding what it takes to fix the "White Spots Plague"
Post #166 contains a synopsis of what you need to do to correct this problem.
