Kindle Fire HD 2013 Black screen but I hear sounds.

"I had this problem and just fixed it in a way you won't believe . . . Remove the battery and put tablet in the oven at ~ 120 degrees fahrenheit for 10 minutes! I had posted problem in Google+ forum for the 2013 KFHD and that was suggested. Here's link: https://plus.google.com/1049775360491655...

Boy, was I skeptical, but the tablet screen is now working. Here's detail:

I charged the battery, then removed it. It was REALLY hard to get out. If doing again I'd for sure get iFixit's spudger, but I used a 3/4""-wide length of credit card to get started, then a couple heavy-duty plastic knives. The battery is thin and wants to bend so this has to be done carefully.

I set oven to lowest temp, 150, and used an oven thermometer, (which also had lowest temp of 150, so there was some guesswork involved in getting the temp right.) Anyway, after preheating I turned off oven, let it cool down until thermometer went below 150 (guessing when it was about 120), and then popped in the tablet for 10 minutes, leaving oven off. I let the tablet cool down, reassembled and plugged into computer and voila(!), screen came on. I didn't get the back on tight at first so power button didn't work, but fixed that and now Kindle is working great!"

you need to hold the off button for twenty seconds i just did it it works. After you press it wait a bit

"How do you take out the battery?

Where is it located?"

Well I am Currently got The same issue as you you have to take out the battery and put it back in

After changing the battery on my Kindle Fire, I subsequently experienced the same issue with the black screen and beeping sounds from the power and volume buttons. I’ve tried everything suggested, such as the hard reset for 20 seconds, removing the battery connection and even putting the Kindle in the oven for 10 min. but nothing worked. I wonder what I damaged while replacing the battery? If anyone has a guess, I would appreciate the help! Thanks
