Chances are--panel's toast. There's a lot of this happening lately....

Yes, I have to agree. I had a cracked screen 32" which had a very similar look, and one tab bond was getting very hot...

Before you do dispose of it, you could try checking the t-con VGL and VGH voltages to see if they are OK -- small chance of bad t-con.
