My Nokia E73 won't charge

SOURCE: my nokia E5 won't charge, I've tried another charger but still nothing

can you see the pin in the charger socket? these can get bent, other wise looks like your charge socket has come free, from the board

you must change the charging block /base pluck or go to the service provider will do it for you. advice by dogy.

SOURCE: my nokia n95 won't charge,

First check the charger by using it to charge a different phone to determine if the charger is functioning fine. After doing this check the battery is properly installed if both options above are in good condition then sorry to say but the central board on your unit is probably bad and will need replacement.
the central board is the main component of the phone and acts as thee brain of the device, all functions go through it. When you purchase a new battery the unit should at least come on even if the charging function does not work.
best refer it to an expert to determine if the entire board is spoilt or just the power segment of the board.
Hope this support has been helpful?
