Query: PLEASE DO NOT BUY

I'm only giving this piece of junk 1 star because the rating scale is from 1 to 5. I wish I could give it a -10 !!!!Unfortunately I did not read all the reviews of this product. I was in a hurry to buy a portable DVD player and saw the screen size for the price. BAD move. I too have the problem with the black screen. I was at home watching a DVD on battery when it flashed the "low battery" warning. So I plugged in the adapter. The screen went black! I tried removing the battery and running on adapter. BLACK SCREEN! I tried replacing the battery and having the adapter plugged in. BLACK SCREEN! I charged the battery and removed the adapter. Tried running on battery. BLACK SCREEN! I guess I'm now stuck with a $300 paper weight!DO NOT.......I REPEAT..........DO NOT BUY THIS DVD PLAYER!!!!!!!!I wish I hadn't!
