Nokia 3310 no display

[supremegsm]

HI

I HAVE A NOKIA 3310 SHOWING NO DISPLAY AT ALL. TRIED CHANGING WORKING DISPLAY. CAN SOMEBODY HELP ME WITH THE CIRCUIT.

for locate broken pads use ohmmeter to check all pads against GND. and compare it with good 3310 pads.

see the manual for pads connection. if conection broken goes to cpu try to locate them near the cpu - on the pcb lots of holes you can check wit the good fones one by one.

wit patience you could find the broken pads...


good luck

first off all check for prensence of 2.7 volts in the pcb board where the lcd connects, and also the O volts..

[abbeydguru]

try cleaning the lcd connector properly and check whether there is no damage on the connector

Try change the c409 and 410 ...tested and it works on many phones ...
