The only fix is light engine replacement. Search google with UX27712R part number. There will be many sources. All are rebuilt engines. If consumer buys the part and installs with no success, part suppliers will bring up issues relating to damaged by user or incorrect installation.

After replacement there may be some alignment issues or faults caused by incorrect installation and assembly.

Experienced technician that has changed an engine before, usually under warranty, has had an opportunity to learn the correct way to do it in a shop situation with known reliable parts.

User replacing may have a "no start" or "poor picture" situation and not have the experience or skill to recognize a secondary problem, minor connection problem or defective replacement part. It is more complicated than a fuse, bulb or other minor part replacement.

Hi there.

I am a service tech.
After reading about the this particular l.g. set i decided to llok into the optic engine and
have found that the blue polarizing lense is crook.
Believe it or not but the set will work fine if you remove this lense, alternatively if you remove the lense
and want to replace it. Go to ebay and type in hoya polarizing lense. Buy the 72 mm circular lense.
Then cut it to size and replace it .
Has fixed many of my customers sets.

Hope this helps.

Blue splotch appeared in lower right corner of the screen

I had a 52" Zenithe LCD with the same problems that you are discribing and since I work in the industry I have a relationship with a couple of authorized service centers. I took a digital picture and emailed it to both of them and both replies were that the light engine was going out and it would be cheaper to buy a new one than to fix this one. That is the bad news, here is the good news. LG/Zenith has lost a class action lawsuit regarding the light engines in the LCD rear projection TVs. The settelement includes extending the manufacturers warranty till 2010 and/or repayment of money paid to fix, calibrate or replace the TV.
