Hello,
Please, I would very much appreciate someone sending me (e-mailing) the complete service manual for the Nokia 445Pro, 445N chassis. This should include all the 50+ pages originally present in the document. There were several links posted on this forum, but unfortunately, they are either not working or the file/info is truncated. I could not find the complete document so far.
I have several issues to fix with three of these units:
a) The brightness related to the adjustment of G2 voltage - fully explained on this forum;
b) A more serious problem involving probably bad solder joints. At power up, before the computer actually boots up, the monitor displays a fully red screen that flickers uncontrollably
[Why RED? I am not sure, but I believe red because there is something that affected this color or the other two even before the flickering problem appeared, namely a red hue, but it could also be from the video board (Matrox G400 dual- the second channel has a bluefish tint).]
After boot up, the screen is still fully red and flickering, no image present, but while the monitor heats up in the next few minutes, the image apears. Also, the width increases suddenly at times and a tap/slight shock to the case brings it back. Suggestions are very appreciated.
Thank you very much and best regards.
Dan C.
