NOKIA 3230 repair solutions

Well today here i am to discuss about nokia 3230 handset, which is good looking and comfortable handset. But there comes problems in its maintenance, either we can say its maintenance is some costly comparitively to other handsets. Its one drawback is, that its on/off switch, camera, display i.e. lcd and joystick are all on front pcb board, it has two pcbs, one is of keyboard and other is main board which are attached by the help of flex cable, and its repairing of flex cable is very difficult, so these handsets could not get so popular in nokia world. Because when we have to repair its lcd problem or camera problem or joystick then we have to change its whole front pcb i.e very much costly. Then it has keypad ic, display ic in it, if they get damaged, then we can repair it by replacing them or we can make all jumpers in it without ic, their jumper pics will post here later and its network fault is also very difficult to repair. So overall, feature wise its very nice handset with memory card, bluetooth, camera with good megapixel, but due to its some repairing drawbacks, it is still behind in the que. Well it has also boot ic near right side of battery conector, which have to be replaced if get damaged to get rid of nokia pause on display problem. Its small battery is good backup battery, but it should be charged only in limited period around 1-2 hours, not more than that, if u do , then it will get destroyed, and charger of it should always use original one, that output good supply to all components as per requried.

REPAIRING OF NOKIA 1600

Dear nokia 1600 handset is a colored handset with polyphonic ringtones has loud sound. Its attractive look makes it famous inNokia world. It is the cheap and best colored handset with handsfree function also in it. Its repairing is somewhat like nokia 1110 as described above. One more point i would like to discuss in it, is that we can convert nokia 1110 to nokia 1600 or nokia 1600 to nokia 1110 by changing their softwares and display respectively. If it got ringer or speaker problem in it, like if both speaker and ringer not work, then just change its ringer because in this handset ringer and speaker is same. And if only speaker is not working, ringer is working, then check the small resistances on the front above side of the pcb that either any component is break or damaged with water. And if speaker is working and ringer not working, then check its ringer ic or change it. The other common problem in this handset comes is of handsfree symbol on display, inwhich speaker , mic and ringer stops working. so first of all check charing jeck of it, because if jeck is not touching the points properly or damaged by water, then change it. and if still it got problem, then check components near charging jeck points and ringer ic could also be short in this problem. Well its flash and UEM ic are fixed with gum. so it is difficult to repair. Cpu can repair because it is not fixed, and if handset has contact service problem in it or its going on hang or restart then just reball cpu or replace it.
