Sounds like you need a new AC adapter? Contact the manufacturer or look at the model number of the AC adapter and search the internet. Otherwise you could try mouser.com or some other site that sells adapters and make sure you have the correct input and output voltages(also correct AC or DC output) current rating equal to or greater than the original. Finally the plug needs to be the correct size, 2.1mm, 2.5mm, etc.
There is no provision to input DC to this device. It is only designed to work on AC only. There are only AUX in and out sockets and a co-axial cable antenna input at its back connections. If you haven't AC mains connection, you have to contact any experienced service techinican to take a wire connection out of it. to that connection you can connect the battery. Ask the technican to make a diode protection to the connections he set up for reverse voltage protection. OK.
Hi, yes I have an idea what might be the matter, especially if the iPod was in the cradle at the time of the accident, you probably have a couple of circuit board contacts that came loose at the point where the docking terminal meets the circuit board. Fixing this will require some pretty precise soldering and the use of a strong magnifying glass. The broken solder joints will not look quite like the unbroken ones, they may actually be up off the circuit board a bit-or where the solder turns into the green circuit path may have a crack. Either way it will require some nifty soldering as I said. To fix a crack in the green circuit trace this will require scraping a little of the green off the circuit trace ( actual color of circuit board varies slightly by manufacturer ) exposing enough of the copper to solder back across the gap to restore conductivity. This may need to be repeated several times more than likely. Also to find the cracked solder joints you may try to wiggle slightly the entire docking connector while looking at it under magnification, then you may better see the defects. I hope this was of some help, and thanks for choosing FixYa,good luck-Prodzilla.
check ac coming in, then go to the rectifier and check for dc volts on the plus and minus, check voltage at 25 volt 10,0000 uf cap should have voltage present. check positive solder joint at the cap and print board.
