helo !
When I try to turn off the h340. The screen freezes displaying the message "Please remove external battery pack". If I use reset it will turn off when this message is displayed. When in use the player thinks that it is charging even when no power supply is connected in spite of this the player functions, charges and transfers files when required and only produces an error on shutdown.
I think that the problem might have been caused because the USB port was connected inverted to the motherboard and hence the polarity of the power suppply was inverted. If this indeed caused the problem can anyone think of a solution. Are some of the internals damaged? If so could I repair them myself.
I know there have been threads on similar topics before but if anyone has any ideas, suggestions, or solutions could you please repond. Any help will be greatly appreciated. Thanks.
I chearsh the firth chip after the USB power... I think, there is the Microsemi LX2201, Philips PCF50606HN/03A/N1Y or Philips TEA1211 DC/DC Converter, but i m not shure.
thanks.
