I apologize, but i recently changed the component with a new one and problem still occur...it still need some cold to boot
It must be another componet nearby.

Hiya !Hi,originaly, we thought it was this one:View attachment 143383
We changed it. It worked for like 10-20 switch on, then it failed again... Now i got my wii u always opened with a cloth on it (for dust lol) and i apply in this area of IC's some cold spray then it start...
So weird...No one can explain to me why it behave like that...
Cheers.
Hiya !
Man a few questions :
Has the game worked with a replaced drive just after replacing the transistor you have mentioned ?
Because my console doesn't boot with its original drive you can check my journey here :

Anyway I'm going to check this transistor you've mentioned.
Many thanks.
Do you know about the cold spray effect please ?
based on markings on Q8, it's this component here: https://www.mouser.com/ProductDetail/Nexperia/BZB84-C2V7215?qs=sGAEpiMZZMuKA4j4J4t1TBorBgfSDkVE
which is according to datasheet is a Dual Zener Diode, and not a transistor, but i don't think it's right from what i'm getting from my board. And C162 capacitor shouldn't be grounded obviously (it should be ground on north side only), so I would just remove it and test it separately to see if it's the capacitor that is bad or the test point itself, which is linked to other components on the board that might be bad if it's still GND after removing it. It's linked to TP114 on the south side (to DVD board connector, pin 21) and goes through FIL19 (cont.), F10 and on the left side of C99 and R120

I've retested Q8 and it's the same type of transistor as Q6 and Q7, so if it's reading differently from those two on your motherboard - then it's definitely bad
you sould get an esr meter to test those caps
Yeah I'll have to pick up one...looking at the MESR-100 V2. They're not cheap, soI might have to start trying to fix & resell Wii U's to pay for the cost of it. LOL
