Hi have been given a couple of Akura Retro Phono n BT Players and of course they don't work, where do I start to test voltages etc on it, getting 5vdc out of transformer and to the board, the battery is giving out 3.7vdc , don't realy know where to test for any voltages , tried to find a schematic etc for it, but no luck up to now.

On one of them the charging light comes on and a blue ( bluetooth ) led comes on then blinks and I can connect my phone to it, but then after a short time it goes off and only the charging light remains on, but no activity with the turntable motor activating !.
on the other one no lights come on .

cheers
Spike

The most likely component to fail is the Li-Po battery.What is the condition of it? If it has a terminal voltage of less than 3V, the charger probably will not charge it. It can possibly be recovered.

Yes I did think that, but it says 3.7v on the battery and that is what it is showing !.
