I am hoping someone here with the vast knowledge on this forum can help me
I have a Nintendo switch which I bought as a spares one but thought id have a go at fixing it. It had a few midding resistors and capacitors around the m92 chip which I replaced. I also re soldered the M92, P13 and reflowed some of the voltage regulators.
I am getting no shorts on any of the usual places. I am getting 5v on the fuse, 4v / 3.3v / 1.8v on the testpads. The battery is charging at around 0.38 amps on a 5v charger and is near fully charged.
When I hold down the power button for around 15 seconds the amperage drops to around .22 fluctuating a little and as soon as I press the power button it jumps straight back up to around .38 amps again like its trying to turn on.
I have tried shining a torch on the screen and don’t see anything, when I touch the screen I get no sound. Plugged into a dock the amperage drops to around .11 - .18 amps and immediately jumps back up as soon as the hdmi cable is removed and back down as soon as its reinserted.
I am at a complete loss now after spending 2 nights trawling the forums for similar faults and taking several different measurements trying to fix it.
Any help / thoughts / things to try will be much appreciated as I am now out of ideas
Thanks in advance
