Hi,

I'll try to help to find out the mods. Could you measure voltages of your card ?
If yes.. please measure carefully DC-voltages of pins for '1575 PVGO' chip. Also voltages between + - node of 'bulky' capacitors (large electrolytics) might help..

yes
I go to try to measure :)
how I identify the certain pins to make vmod?
and
what it is "DC", when you speak in "DC-voltages"?

thank you

There is allways (?) a small marking (e.g. 'spot') for the first pin. The numbering goes counter-clockwise starting from pin '1'. Please, post a magnified foto of chip you have still problems..

DC = direct currect e.g 'normal' voltage you can measure e.g from a battery (opposite to AC..). Are you familiar to measure voltages of equipment/PC while power is on, and aware risks related to measurements ??
