Hi, it was discussed some time before, one solution is to change displ. to the one without capacitors on the back, but there MUST be another solution too, maybe in wintesla, i dont know, it only need to set higher voltage input to the displ. but i still dont know how, i have one 8210 with this symptom too... <img src="mad.gif" border="0"> ...any idea guys??? <img src="confused.gif" border="0">

If there are voltage fluctuation, this phone may have troubles with network too. Easyer way: Measure voltages from CCONT. In service documentation there are all voltages and corresponding testpoints. Problem is well known Nokia's CCONT bad soldering. If resoldering does not help, replace CCONT. Good idea is to recalibrate all ADC/DAC with Wintesla.

thanx

Recalibration is used to tune ADC/DACs for proper battery charging and battery measurement only! You can not change VBB (Baseband supply voltage). It's 2,8V and can be started or stopped only (via control register of CCONT).

Where can I buy a display without capacitors... capacitor = condenser??

what about changing the rubber? Is not a better solution?

thx!
