Hacking Hardware OLED Picofly: sleep mode battery draining + Joycon jiggle

[Eds05]

Hello Guys,

I repaired another OLED switch, this time a Zelda edition, but in sleep mode the joycons are jiggling and the battery is draining like hell.

What I already tried:
- I swapped the MB in another oled console and its the same,
- same with another joycons,
- same with different modship (instinct nx and picofly),
- same in CFW or OFW,
- same if I restore the emmc,
- same in airplane mode.

This is what I repaired on this console:
- broken CLK line
- screen connector replaced
- permanent dat0, I reballed 3 times the emmc to try to get rid of this issue
- CMD resistor replaced

On this console the instinct-nx was taking a lot of time to gitch the console, so I replaced it by a Picofly.

But to not have a slow emmc mode I had to add +47ohms on the CMD point, and +3x47ohms on the dat0 point.

I did maybe 30 oled modchips, with only picoflys. Usually I only add +47ohms on the CLK point to not have a emmc slow mode.

I find nothing on internet about this issue.

What could cause this issue ?

Thank you

What do you mean the JoyCons are jiggling?

 

[Eds05]

They are doing little vibrations, briefly and randomly.
Only in sleep mode.

Are the Joycons charging? Do they work wirelessly? Check right joycon

Hello,

Yes everything is working regarding the joycons.

But I noticed something, If I launch Lakka, when I turn off the switch (sleep mode), the switch wakes up few seconds after. Maybe on the switch OS the console is partialy in sleep mode. I mean, the OLED screen is off etc... but not the Tegra or something else. Cos if I put the switch in sleep mode, the APU is a bit warm even after few hours, really noticeable if the console is in his case.

I think I have an hardware issue. Which controller is managing the sleep mode ? I would like to replace it.

Hi, have you checked for shorts beneath the SoC? In Lakka, the Switch can wake itself up if the power button gpio pin is shorted. The joycon issue might be related

I just removed the APU to redo the clk line, it was almost covered by the APU after a nuke bomb on it. And I saw anything broken except the clk. I also rebuilt the cmd line and change an almost broken sp2 capacitor on the APU (could be this).

Im waiting the stencil and some resistors to reball the APU, put a new cmd resistor, change the oled screen connector and it should be good

Hope this standby mode will be fixed

About the joycon, even with the sliders disconnected from the main board I had the sleep mode issue.

Hey, I have the exact same problem, I'm looking for a solution too. I too managed to damage the display connector and had to solder a new one. Check if your cooler is spinning when the joycons are connected and the console is sleeping.


Maybe the problem is in the chip next to the EMMC memory, maybe something happened to it from the heat?

My console drains about 7% per hour, in sleep mode

Thanks for your reply. Interesting your case. I should receive everything to reball the APU this week and Im gonna see if the fan is spinning too.

Start the game so the ventilators start spinning. Close the game and lock the console. watch the fan, if it does not stop spinning then disconnect the joycons. But I'm sure we have 100% the same problem, we need to unite and find a solution. We need measurements of all the major components from a working board.
