My xbox1 (110v) accidentally plugged to 220v. I cant remember if i hear a popping sound like others, but im pretty sure that theres a smoke. from that time. my xbox wont turn on.


Psu = 1.4v - 1.5

videochip = ? ('Focus" was written on it)

" * 110 volt Delta V1.0~V1.1 PSU's (2 required) use varistors: 7D151K
* 110 volt Delta V1.2~V1.5 PSU's (1 required) use varistor: 10D241K
* 110 volt Delta V1.6a~V1.6b PSU's (1 required) use varistor: 14D241K "

So i can pretty much say that my burnt varistor is 10D241K?

After i took my ps2 off. You can pretty much tell that the varistor is burnt. (i thought it was a capacitor). The Fuse there seems to be fine by "just" "looking" at it. Btw, the fuse is a small fat round thing. pretty unusual than the normal ones ive seen in Psu repair tuts.
(low quality.. sorry)

I replaced the Varistor and the Xbox still wont turn on.
Iam on a vacation right now, as soon as i get the chance to go home, ill go try to fix my xbox with all your help. :-) thanks. :-)
anyway, what do you think is wrong? are there other broken components as well? like what? Fuse broken?
capacitors? resisitors?
There are no burnt marks on board though.
Thanks for helping. :-)
