I recently bought a used PRS-505 on Amazon Marketplace and when I turned it on, it has a vertical line of light pixels from top to bottom in the center of the screen. It looks like a line of dead pixels. I tried a few books and it's still there. I notice the batter shows only 2 bars (about 50%?). I emailed the seller and he stated that I needed to charge it more and it should go away. After googling and searched this forum, I didn't see anything about a "dead pixel" look-alike line when low on charge.
I will find out in a few hours when charge is complete (red light is off). I doubt it will make any change. Should I try the reset hole in the back? Any other suggestions? He seems to be responsive to communication so if I can try things to make it disappear I am open. If not, I can always proceed with claim process with Amazon and/or Amex card. Thanks for any inputs and suggestions
