Hi folks!

Need urgently schematic for Nokia 445x or an advice how to repair the fault!

Problem is that about 25% of the screen are gone.
Seems to me like a bug in the vertical deflection circuit.
Found this problem on an internet repair database but
no solution. Seems to be a well known bug.

PLS HELP Crying or Very sad
