I have a Toshiba 57H84 that went dark on me Monday night. I still have a picture, just a very dark, somewhat blurry, crappy one. I've had to set it "Sports Mode", which is very high brightness and contrast, just for it to be watchable. I'm wondering if watching it in this state will worsen the problem, until i can affort to fix it. This dang thing is 5 months out of warranty...so i'm stuck with the bill.
