Left side is too dark. How to fix it?
I got the TV in 02/2009. In 02/2011 (just after the TV's warranty expired), when I opened the TV to watch something, I saw that the left side of TV was much more darker than the right side.
As manufacturer and repairers say "left LCD panel is gone, replacement price is much more then TV's price, so throw the TV to trash" but I'm not convinced actually because of the following;
Till a month ago, when I shake the TV or wait a little bit, the left side was coming back to normal but in last month, it doesn't.
I'm attaching the pictures. So you can see the problem and may give some advice to me.
Tim, sounds to me like the backlight inverter is going out. You want to definitely check on fuses or continuity of voltage supply lines going to the X Board/s, (your case check the X Board) as well as the LVDS cable. Replace blown fuses, connect broken lines, and resolder loose solders. Check on the capacitors on your boards, they may be either loose or popped. Look for any leakage on the boards (looks like a oily sticky substance) and check the top of the capacitors. they should be flat. Any bulging indicates a failed capacitor, The older LG's have the backlight inverter power separate from the power supply, and in that case you will require a new LCD Panel. Very costly, if you can even find somebody who has them for sale. The newer LG's have the inverter connected to the power board. In that case you could try to fix it by replacing the power board. It would be great if besides the model number you could find the Chassis number. It might be possible to get a service manual for you and give you some more specific details for your TV. Hope this gets you started in the right direction. Good Luck.
