We have a Sony Bravia KDL46V3000, manufactured 7/2007. When first turned on, the screen is very dark, especially on the left side. There are also 3 or 4 horizontal bands visible, especially on the left side. After about 5-8 minutes the screen brightens up and goes back to normal. It only happens when the screen is cold, not after it has warmed up. Please help!

I have the same tv with the same problem. My tv is about 3 1/2 years old. I took it to the shop yesterday and today they told me that I had a bad lcd panel and a bad FL1 circuit board. They also told me it was going to be $3800.00 dollars to fix. I am now on my way to buy another tv, needless to say it will not be a Sony. Sony knows about this problem and refuse to do anything about it. Good luck.
