Thanks for the picture - that's a big help.
It looks you have the dreaded light tunnel collapse common to all LG1.gif DLP TV's. Inside the light engine there is a square tube made up of four mirrors. These mirrors deform and crack with the heat of the lamp. They fall down over the light aperture and cause a shadow of varying degrees. It is fixable now at a realistic price ( used to have to replace engine) as LG have made the parts available. It would take a competent tech around three hours to complete or if you are technically minded you could do it yourself. I hope this helps.
Hope Ya Fix It!

I had a similar problem on my Fujitsu-Siemens Lifebook C-1020 and I had to replace both the C/C inverter that the CCFL lamp. Easy to find/replace the inverter (only take care of input/output plugs), tricky to find/replace the CCFL lamp (because of diameter, lenght and toxic Hg content).

Have fun!

Tekcolor correction should take care of that.

i just had the same problem. after talking to many tv repair people i finally got a knowledgeable person to help me. i ordered the part and fixed it myself.
it was very easy. i have an LG model# 50px1d. so if you had this problem i suggest you order the part yourself and fix it. i got an estimate for repair and it wouldv'e cost me at least $500 parts and labor. i paid $230 for the part. so you can see i saved a little more than half. the part you need is the " Z SUS " ASSEMBLY. you can order the part from LG website. the part # is 6871QZH044C.
let's just say after doing everything myself, i am watching TV right now.
by the way LG would not help me at all. spread the word that LG is not a good product.

hi, usually you can correct this issue with only a few system checks, dark streaks can be caused by damaged pixels on the screen, in which case you need to replace the TV.
  • Inspect where the dark streaks are on the television. If the streaks occur at the same place on the top and bottom of the screen, they are due to the formatting of a movie or television show you are watching. This is normal. Also, if the streaks appear on the left and right of the screen, they are due to the show being filmed in full-screen instead of wide-screen. This also is normal.

  • Change the input setting so you are viewing the contents of a different device. If the dark streaks are gone, you know they are due to the device connected to it. However, if the dark streaks remains no matter what input the TV is connected to, the problem lies with the television.

  • Inspect the cable connection. Oftentimes when connecting a computer to an LCD TV, you can have strange dark streaks across the screen. Use a DVI-to-HDMI cable connection when plugging in your computer, then press the "Menu" button on your TV remote, select "Picture" and chose "Square Pixel." See whether the image adjusts and the dark streak goes away.
  • Contact the manufacturer of your LCD television if the dark streak remains. This streak can be caused by a defect in the television; if the TV is still under warranty, you can have it replaced.

    Two thirds of the picture has gone dark on 42lg5000-za tv


    Hello,

    The problem actually is from a lamp in the unit, it is getting damaged gradually that is why it is two third of the screen that has gone dark. once it gets completely damaged, the entire screen will turn dark.

    Try to ***** the lamp of the television and replace it with a new one.

    After doing that your television will be in good condition once again.

    Take care and good luck
