Hai, In my country, we do not change the main board, because the cost is equal to the price of a new, why you need to buy the main board under the warranty repair only the longest one month? whereas if you buy a new or used, it is more worthwhile. If you have tried to change a new LCD display screen, but the results remain the same, perhaps it is divided UEM ic problem, this happens because you always fall. ic is too close to the frame. hentakkan effect on the frame due to falls, may interfere with the original position, if the worst Solder balls under the ic off. If you are lucky. Try to heat the surface of the UEM ic, add Solder flux before the process is done. Solder balls when you get looked melted, press the top surface is a soft ic so it does not directly close to the surface of the board, as this can make Solder ball attached to one another, if you have a place to sell spare parts for ic, it is better there ic change is the new home you buy a new board. cheaper cost, but I do not know the cost of installation if you sending to your technician.

My nokia n70 cannot start, got light on but it just won run :-)

Do you have a white screen and did the phone doesn't move after that??If that is the problem then your phone may have been infected by virus or you would have repeatedly dropped your phone..Switch off and on the phone by removing the batter and if this doesn't solve your problem,Your symbian os software should be changed to solve this problem.It generally costs Rs.250 to Rs.300.I got the same problem in my nokia N72 and got solved in this way...Best of luck..

Touch screen not functioning after falling down

the touch panel costs 1500 bucks if u give it in redington, chennai.
phone lock cost depends upon availability and the goodness of the service people. I got it changed for 115 rs. Board and socket connection, am not sure. But if u ask me, better buy a new one than spend this much amount.

RS-25 foot pedal not working

The foot pedal needs to be plugged in before the software is installed. Just uninstall the software (your files will be fine) and reinstall with foot pedal attached.
