Question about LG RU-52SZ51D 52" Rear Projection HDTV-Ready Television

1 Answer

LG DLP Projection TV Green/Brouwn vertical Bar

We have an DLP Projection TV from LG Model RT44SZ21RB.
I replaced the lamp about 2 months ago and now suddenly a 3 CM brouwn/green vertical bar has appeared on the LH side of the screen.
It is kind of transparent but not clear.
Is there anyone who also experienced this and can suggest a way to fix.
I do not want to spent too much bringing it to a electrician since I am not completely happy with the TV nor with the LG support ( no LG for me )

    I took the TV to the repair facility since the so called light tunnel was collapsed. likely it is not too hard to replace it yourself but to get access is the issue you have to dismantle almost the whole TV so at the end got it fixed for 300 AU $ now picture cristal clear again.



    Thanks

Hi there.

The excessive heat from your lamp has burned one or 2 polarizing lenses.
To replace this you have to pull the optic engine out of the unit and dismantle it.
You will see 3 square lenses in there, remove one by one until you find the burned one.
Then go to ebay and type in hoya polarizing lense.
Buy the 72mm one and cut it to size.

hope this helps.

My Toshiba dlp 62hm116 was used for 3 months then stored for 2 years, I turned it on yesterday and it makes a loud grinding noise which I think is probably from the exhaust fan area and the picture is black except white at both vertical sides. It worked fine the last time I used it 2 years ago. Any ideas?

I have an LG DLP. that turns off after 15 -30 seconds


If the second light is blinking to orange or red, that is usually the lamp indicator light on an LG DLP tv. That indicates your bulb needs replaced, or something surrounding the bulb has failed (like the cooling fan for the bulb for example) IF you have a spare bulb handy, I'd replace the bulb, keeping in mind if you touch any part of a new bulb with your bare hands, you just cut the life of the bulb by more then half.
