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

1 Answer

Red discol Hi there, i live in Australia and i have got a LG 111cm RT-44NZ21RB, it has recently started to develop red discoloration on the right hand side of the screen (slight red shadow). The rest of the tv is fine and you can still see the picture. Just wondering what this is and why it is doing it? Also can it be fixed by myself or do i have to take it to a repair man and if so what kind of cost am i looking at (Australian Dollars)? Is this a major problem? Thanks

Hello csumbi,

There might be a problem with your light engine since you are using DLP technology. I would suggest that you check the color wheel or the LED matrix. The check the Fresnel lenses along the light paths. These are more like causes of that red discoloration. The fix is usually to replace the light engine. I believe you can get a free estimate from any TV repair shop, which is your best bet. I am unable to tell you the cost in Australian Dollars. Is it a major problem yes it could be if your light engine is a sealed unit requiring the whole thing to be replaced. You can fix it yourself, but you will need the part number, and a schematic to show you how to remove the light engine.
I hope this helps,
Thank you,

LG rear projection colours out of alignment

I have a similar problem with an LG (except my red is the one that is fine) and was able to talk to a tech in some detail about it. The tech prefaced by saying that he had done a hundred or so of these with exactly the same issue. This is very common and the life span of rear projection televisions is not great. Having said that, plasmas and LCDs are also limited in life span mostly due to modern high performance gaming machines which shorten the lifespan of monitors both plasma and LCD alike.

From what I have gathered, this is not a problem that you can easliy sort out. (Of course they would say that though) It involves replacing the digital board which means soldering followed by aligning the lamps which requires quote a lot of expertise.

The part itself apparently costs around $200 Australian and the labour will vary for the cost of the technician but I was quoted that the labour was about the same cost as the part.

Not sure if I would call this solved but I hope it has been at least a little helpful.

Hi. i have an LG 42inch plasma, approx 18 months old. about 2 months ago, a green stripe developed down the right hand side of the screen, approx 1.5 inches wide. last week a 2nd stripe the same width...

Sadly, the plasma screen is failing. The green strip is no longer functioning properly and the failures will continue to progress.

If still under warranty, get it exchanged.
