I posted this in a long thread with an off topic, so for clarity I thought it would be best to start a new thread.
I have had several PM's asking about the blue polarizer replacement for the Sony VPL-HS10. So, I'll just respond here.
With my current total hours of 14,267, I've seen this workhorse show what is truly capable of.
Please take the time to read:https://www.avsforum.com/avs-vb/showt...72#post7320772
you can download the service manual at:http://www.stevenhightower.net/hs10/ServiceManual.pdf
Yes, I did have to replace both the polarizers.
You have to remove ALL connectors and unscrew and remove the entire C board. Don't worry about marking the connectors as they are all keyed and can only be placed on the board correctly. Be carefull of the headers conncting the C board to the riser boards below it. Refer to diagram 1-2-4 (C-Board Removal)
Be very carefull when unhinging and removing the three ribbon cables from the LCD pannels, as the plastic is VERY brittle on the little snaps that hold the cables in place. I broke one side of one of them and had to use a bit of epoxy to hold it back in place.
After you remove the c board you can remove the polarizers. Remove the screw and you can slide the Blue OUT Polarizer straight up with fine tweezers. (9-885-029-41) $175.36
You can also remove the blue IN Polarizer the same way. (9-885-029-40) $162.00
If you burnt one of them so bad that the blue is weak, you have burnt both of them to the point that they will need to be replaced as a set.
Refer to diagram 4-4-2 (Optics).
To order the parts directly from Sony Parts, call:
1-800-538-7550 Option #1.
Or just place the part #'s in at the Official Sony site and buy online.https://servicesplus.us.sony.biz/sony-parts.aspx
I called and they only have one polarizer in stock with a 2 week backorder for the other one. They are becoming popular parts with the age of the hs-10/20.
Edit: Good point I should have included:

The second one had a printed line on the film as well as the bubble and that's when I realized the film was there. Make sure you remove the film from both before putting them in!
Also, to save some coin, you should inspect them before you order. It appears that the outer one failes much worse than the inner one (Closer to the bulb.) I saw damage to both, and demand a great picture. Dave was aible to get away with changing just the outer one. YMMV.
