No, no need. They will be happy to sell a $3,000 new light engine.

When I said it was time to get resourceful I meant it. That should
explain why I posted. If my assumption the this pale red piece of
plastic is a prepolarizing filter the issue becomes how to orient the
replacement.

So many people are used to going to the manufacturer, and if it was
worth it I would. I would even pay them $40 or so for a fifteen cent
piece of polarized plastic, but it's $3,000. I have no intention of
contacting them, I can source polarizing filters.

To give to an idea, we just bought a $4,000 truck for $350. Needs a
tranny. No it does not. I am not going to GM for a tranny, or for the
gear therein. (5 speed manual, no reverse). I'm going to the
transmission people, not the OEM of the truck.

"We" have been doing things like this all our lives, but the LCD
projection thing is so much more involved I was hoping that someone out
there knows something.

I can probably shine light through the panel and determine the
polarization, maybe. I can assume that being unpowered the pixels are
in the untwisted state. Do I assume this is black, or white ? (blue)

Gotta understand what I do. We the unknowing, led by the unwilling can
do so much with so little, that I have gotten to the point where I make
more than the boss. I do so much without any help from the manufacturer
that I simply do not consider it an option anymore.

When we get into this transmission we will not be buying tool
J113456798 and J877543, I have a lathe and can make the dummy shafts so
that during disassembly the cluster doesn't fall all over the floor.

Even if this Zenith needs a dichroic mirror, I will find a place that
makes them. I already have. And lemme tellya, I might be able to get it
for free. The trick there is not to tell them you are repairing
something that is already built, you gently lead them to believe you
are an OEM building a prototype. They will send free "samples". My Mom
taught me that.

The way the manufacturers treat ISCs I am used to it. I used to work
for an ASC and I couldn't stand it anymore. The support was there, but
that didn't help the build to be any more servicer friendly.

Look at what these manufacturers do, and you think they're your friend
? Ha. They indeed have the upper hand, but I have been the underdog all
my life, and I have prevailed. As I ask for help, I also share
information.

No sir, I have no intention of contacting LG, by the time I sit on hold
for two hours the shop has lost hundreds of dollars. Then I will find
out what I already know, replace the light engine to the tune of
$3,000.

The interests of manufacturers and servicers are diametrically opposed.
There is no anger involved, they operate in their best interests. Well,
buddy, so do I. I will not, however, feel sorry for them when they
can't sell another TV for $5,000 that only lasts two years.

You should try an Email/Fax Campaign, to the Source of Mfg LG in
Korea/or wherever it comes from. A Courteous inquiry to the orient
will often get results. Like how pleased you are with the Quality and
innovations of LG, etc, and how yours has this small minor Red
Filter problem you are trying to remedy. You want to restore the
wonderful picture you used to have. You have been unable to get good
results from LG Huntsville etc. Go on and on, etc. I once did
this with My Dads mazda rotary, and later with my 626 head gasket
problem. I got a $800 refund direct from Mazda for my efforts.
