Hi, Willy,

I read in an old post, you wrote and I quote "use wintesla to run test menu -> rf test and set RX, with ch 60

then test VCO C558, see is it 2.745v

1. my problem is I've got 2 nokia 8210 with no signal, with rssi reading -118, what do i change

2. Sorry to sound stupid but how do I measure VCO C558 using wintesla


thanks alot,

Black-Axe,

sound not "stupid", at list you try to know what happen your phone, and it correct way to repair phone


TO measure C558, it is for 3310, to know loop from Hager to VCO ,,it can be range from 1.2V to 3.2V at around 216 hz,, you have to use oscilloscope to "see" it !

first check VRX , VTX, V,,,,,, from CCONT ,

and for 8210, you have to measure that VCO at C802 !( by oscilloscope)
and go to R530 ( in RX brust mode) to see that RX IP/QP -> oscilloscope too !


for your 8210, that RSSI -118dbm, how about TX ?
is TX working ?
TXP, TXC and TX detect, you have to measure it too !

most time, if it is -118bdm, i will check antenna switch , and 26Mhz Vp-p, and COBBA !
