Question about Polaroid PDM-0723 Portable DVD Player
No problems with DVD player for 2 yrs until it stopped charging the battery and we couldn't use it unless it was plugged in. I figured the battery was toast and I bought a new battery through Polaroid. It comes in the mail, we test it, and it also won't charge, so it's not the batteries. I hooked up the AC cord to another item and it gave it power, so I think it's something internal. Any suggestions out there?? Thank you!!
Try cleaning the batter contacts with a pencil eraser, sometimes they build up a residue that prevents good contact between the battery and the system. If that does not work the problem is either in the rectifier circuits or one of the many small transistors on the board. A rectifier circuit is made up of diodes and it's main purpose is to change AC current to DC current as that is the type of electrical current all electronics work off of. The transistors act as switches with special purposes and properties. The proper way to test these components is to remove them from the circuit and test them with a multi-meter. The bad news is you will have to have a qualified technician to do this, so that means a trip to the repair shop. Hope this give you some idea of what might be going on.
