7" Top Loading Portable DVD Player with Carrying Case
I think I figured it out.
I bought this DVD for my granddaughter for Christmas.  My daughter called a couple of days later and said that it wouldn't work.  After charging it would only play for a short time and the screen would go black.  I went and got it to send it back, but I decided to read the manual and play around with it a little first.  It stated in the manual that the \\"Ni-MH batter will not be fully charged the first time, so the discharging time will be short. The battery will take a full charge after four to five times of charging and dishcarging.\\"  I have been charging and discharging it since yesterday.  It is now charging for the foruth time.  After the third charge it played for 2.5 hours before discharging.  The manual also says that after a period of storage of if not used for a period, you have to repeat the steps to get the battery back to normal charging conditions.  Each time I have charge the player it plays for a longer time (so far).  I think that must have something to do with it.  Hope this helps.
