yes this may be true that there is an internal fault, i believe i did indicate this in my previous post.The main reason suggested replacing the charger instead of fixing it is that repairing a charger such as this in most cases costs more in parts and labor than it would to just replace it.
I've been down this road more than once with these things.
Its faster this way, more cost effective and puts any warranty and liability back on the new part itself instead of you.

Admin,
complaint? i surely hope they hit the report button by accident as there is nothing to complain about i hope. If trying to help someone is bad then i'll just leave.
