Xbox one 1540 not taking disc

[gurj1979]

My Xbox one has stopped taking discs. Sometimes it will trip the power supply and no orange light neither.
If I'm lucky it will randomly take it after about 10 power reboots.

I got a new drive, swapped over the board but same thing.
So I swapped over the motor driver IC, but still same problem.

Is this turning into a motherboard problem rather than the drive or PCB itself ?

Help please.

sounds more like a psu issue

It works perfectly with the drive disconnected though.

I've also replaced the 4 caps inside the PSU, even though they weren't bulging.

then i dont know, the motors are the only thing that will pull current.

If there's someone with Xbox electronic repair experience with this issue, please help. Daughter can't play her favourite Kinect game.

you could either test the supply or the motor or both ..

dont these ones need a reflow of some stuff ? its been a few years since i played with one .. still in bits after i fixed it .. cant remember what it was or not doing now . i do remember it doing something to the supply . might have even put new fets in it ..

Looking at the schematics, it all leads back to the Southbridge chip, which aso handles the SMC.
I'll try reflow that when I get a chance.

Re: Xbox one 1540 not taking disc

So I reballed the Southbridge, but did not resolve the issue.
What I found is that U5C2 is not getting ODD_3P3V_STBY_EN signal, or it's being pulled down. ODD_3P3V_STBY_EN is generated by the Southbridge.
Any idea's whats going on ?

Ok another test. Unit off, disc half inserted, turn in unit with button and the drive takes the disc in, also ilejects when button is pressed.
BUT, if unit is already turned on and I try insert disc, it won't accept it.
I'm totally baffled.
Anyone else know how to fix this ?

maybe the signals that show "tray" status arent right.
i know on the original xbox it had tray-open, tray-closed and maybe a disc signal so the computer knew when to read the drive
did you check the physical sensors that detect the disc and loader position?

Yep, tried 2 drives, swapped over the married PCB. But same thing.
Opto sensors only work if I perform the procedure of half disc insert then power on. Otherwise they have no voltage.

Re: Xbox one 1540 not taking disc

So I finally found a way of fixing the issue. It not ideal but works everytime for disc insert and eject.
U5C2 transistor wasn't giving output. So I bridged 2 pins together. Works a treat.
See the picture.

yo tuve el problema en one s solo que no tenia voltaje en 12.0 la solucion fue alimentar con otra slida de 12.0
