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?

Hi,if its a an LCD RPTV it sounds like a light engine problem.Basically your tv uses 3 LCD chips that create the image .Each chip is like a tiny screen that blend together to get the colors and picture right.They are green,red and blue.When they start to fail you will start to get color discoloration or that red band you are getting.May the Lord Jesus bless you!
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,
