"Where can I buy a new battery for kindle 3"に関する回答From my experience, you don't need to replace your battery, in fact, it seems the ink screen has been damaged for some reason. The part you need to replace is the ink screen. I know it because my kinlde 3 (Wifi and 3G ) dropped from desk and the ink screen damaged, which the screen shows some vertical stripes on the screen. I searched on internet and found out the cause. But I lost my kindle 3 forever, i can't fix it myself, even though i got a new ink screen. I tore it down and replaced the part but it didn't work. If you plan to repair it yourself, handle it carefully! My Kindle 3 get along with me for a long time and i read a lot on it. Amazon made a good product. Hope you can fix your device! =)
"What's this part called? :("に関する回答It's used to dissipate heat on the LCD. As @Mia said, this part should be called LCD heat shield. As for the next question, you'd better not use the electric tape since the part is used to spread heat. Turn to a qualified people in a repair shop to figure it out.
