does power button, click on/off?
have you tried flashing the phone?

sergo_zmeia · 04-12-2004, 20:30

Simple check...with a DCpower supply with current indication apply 3.8V to +and - of the phone...if consumption is 30mA or high U need to flash ..
If its less...U have hardware problem...
Good luck!

if + - are shorted :
may be some capacitors are shorted.there is more than 18 capacitors in this lines!
If you removed chaps,ccont and pf and still short,you need to check many little parts.
just serch for 3310 service manual on forum.but some times MAD cause this fault.

I cant understand relation between buzzer,vibra and led short with VBAt to ground short!
Dont waste ur time with this because:
Led's to groun have R486 and R437 .
Vibra has link to N400 Pin 16 and VB
Buzzer VB and N400 pin 6

Just remove N400(UI driver) CCONT , Chaps,PA,C575,C274,C228,C202,C235 and some other capacitor on VBAT-GND line

intersoft · 04-15-2004, 04:59

mainly pf ccont chaps, hager ic

if not solve there may be internal sorting

Buzzer PADS can be shorted to ground, also VIB PADS, LEDS could have direct connection to ground befor track reaches the I.C .

trying to help, beside i had these problems befor.

thanks you

Dear mansi ,Buzzer ,Led,vibra olnly can short to ground in this case,N400 (UI driver) short to ground not else.
This parts are not in VB lines.If you see any short to ground in Vibra or buzzer N400 has shorted,If you move N400 you will see short gone!
