I have a 3210 that has blank screen:
Changed:
Display,flash chip,mcu+ppm,eeprom(ponyprog),eeprom chip,cobba,and done all that stuff with resoldering with hot air and flux.........
Nothing works..........
Itried several diplays,and 2-3 pšieces of other stuff mention above..........
I'm pissing off with this phone...........
Anyone ahd that problem and now has the solution?
I tried all possible harware and software solutions,but not working........maybe i have to change a resistor or two somewhere on the board???????????

Heya.

Is the display all blank?
when U set the contrast to maximum with nkprofile
is the display a litle darker????
Do u see any sign of life?
Have U messured Vss to the display.
Check the display reset line ect.
I'm supposing ure using a service manual.
There might be an connection ore component failure with the MAD. and then there is nothing to do.
Check all compounents around display.

Good luck:)
