Hi,
Can you help me? I need recognize what types of transistors are used on this board. Have someone a schematic or service manual of this lcd monitor?
Thanks for answer.

first you need to resolder the large transformers.

the fet's are probably these.

Thanks for answer. Can you specify which fet is Q205 and which is Q208? And where I can buy it? I can't find them on any e-shop in my country and in ebay too. Can you help me how to find them or some replacements?

q205 is the AP40p03g

q208 is the AP30t03g

you need to look at the type (N or P) the voltage, current and on-resistance in the datasheet.
then find a similar part that you can get locally.
