i cannot find value of C274 (SC4D7U25V5MX-L-GP) i think this is a capacitor but dont know what value. I need to replace it because it is burned.

i remove burned caps and replace U5 (P2003EVG-GP) it is P-Channel Enhancement Mode Field Effect. And it worked, thank you all.

Hi rtstorm,
could you tell me the numbers and letters for place "U7"? That would be great. Thanks

You can find it in schematics it is P2003EVG P-channel MOSFET

As it is drawn in the schematic, it seems to be a ceramic capacitor.
