Palit Geforce GTX970 JetStream - nie uruchamia się w komputerze

Witam,
Dostałem ponownie tą samą kartę do diagnozy co z tematu: identyfikacja-elementow-gtx-970-jetstream-t63008.html. Nie pokazuje obrazu w komputerze. Po wstępnym sprawdzeniu przepaliło bezpiecznik za portem HDMI. Mam takie rezystancje na cewkach:
L4 - 96,1Ω
L6 - 96,1Ω
L15 - 5,5Ω
L12 - 5,5Ω
L10 - 5,5Ω
L9 - 5,5Ω

Co mogę sprawdzić jeszcze, aby namierzyć usterkę?

Hello!

Measure the resistance on two big ceramic capacitors near the DrMOS U15.

One side have 5,7Ω and the second side have 0,01Ω. Measure two ceramic capacitors.

Measure the resistance between the side with 5,7Ω and coil L9 (put one meter probe on the capacitor, the other on the coil).

Only 0,02Ω

Only 0,02Ω

One of the DrMOS chips U15 or U16 is damaged.

Remove the coil L9 from the board and remeasure the resistances from the post #3.

One side have 4,7Ω and the second side have 0,02Ω.

Also remove the coil L10 and remeasure the resistance.

One side have 6,62 kΩ and the second side have 0,01Ω.

So the DrMOS chip U16 is damaged and needs to be replaced.

DrMOS replaced, coils and fuse are soldered. GPU is working, picture are back. Very thanks for help.
