Usually the 4 NPN transistor are C5707 and 2 P channel transistors are FQU11P06 or FU9024N. You need to try it out

BENQ FP71G Model, Please tell me how can i find the transistor values in inverting section in LCD. like there are 4 NPN power transistors and 2 PNP transistors were there but somebody has removed them before. So if you can send any track or circuit diagrame to my mail.

The power fet and the power ic you need to replace and check all components in the power side. You can try to use 2sk2645 as replacement if you can not get the original power fet.
