Well it seems I located the problem , UG400 (cd3217) is the only thing getting hot , went over the board several times and according to my Qianli thermal cam only one corner of the UG400 reacts to injection , I injected up to 2v. Thanks again 2informaticos

Thanks 2informaticos yes on C5250 I have now 12.29v Ok I will inject , any advice how high I should go :) Tried 1v but nothing got hot ....

On the system side (pin 2) it remains the same 0.035 on the pin 1 its now 0.545

Hi to you all :) I got a 820-02098 board with no liquid and in really nice condition (not even dust) that just died during a Word document according to the client. I get 5v and 0.000A on the charger... I have no knowledge about this board (all new to me) but this is what I have so far PPDCIN...

14.85 is the marked v on the charger but on the schematics its marked 18.5 v and that was what i refered to :) The R7180 was hard to measure .... because it wasnt there :) Put in a 100k there and all works fine :) Thank you dos informaticos for your help

R7012 is 68k , PPDCIN_G3H is starting with 5,2v and going down slowly to 3.9v , with desk power supply its 18.4v as it should be ....

Thank you dos informaticos , I see that after 10 months I was away nothing changed , its still you who works :) I did check the D7012 for a short and it was ok , and replaced the Q7180 and it is unfortunately the exact same symptoms , a short green light every 3 seconds and on the desk power...

Hi Brad , sorry but I honestly dont remember . It was done one year ago so .... :) If i remember correctly it was a corrupt bios but i am definately not shure , long time ago ... I would love to help but .....

on F7140 :) i always thought they should measure the same but i get different values ....

Hi 2informaticos thanks for your reply resistance between 17/18 is 3.3 Ohm , resistance on 27/28 is 20.2 Ohm voltage on R7150 when F7140 removed is 8.58 on all pins Voltages on Q7130 1 = 9.7V 2, 3 ,4,9 =17.94 V 5,6,7 = gnd 8 = 0.6 V 10 = 8.57 V the only thing that shows any sign of heating...

Hi to you all nice people , Merry Christmas first of all :) Got a 820-00165 board with no liquid damage or corrosion whatsoever. Had a short on C7430 , replaced it and ppbus went up to 4v (from 0 ) now the board is taking 23 mA and i am stuck :) pp3v42 is ok and i do have green and orange light...
