Okay some update ...
After I fixed the open winding by redoing everything again the problem went away and now I can adjust brightness and contrast no problem,but I still think that like 25 % of high voltage is missing ,cause I get a dim spot in the middle of screen when I turn the brightness up and it even goes out of focus a bit in the middle ...
Also I replaced a very burn resistor that got hot,but checked OK on multimeter,is it possible if a resister gets hot it jumps of the correct value ??,cause when I replaced it
the picture got slightly better ??
I also used a smaller cap for the boost capacitor a 47000 pf INSTEAD of a 56000 pf
can that cause it to have low high voltage ? almost like the voltage supplying the high voltage circuits is low ??
