Hello. I bought Nintendo Switch, that was liquid damaged. There was bad BQ24193, it was replaced and charging problem was solved. Now Switch start work normally in hendheld mode. But in dock mode it not worked, dock recognize, if plugged (the green LED light), but not output signals. Replacing PI3USB Pericom solved it, but only partially. Now, whan is Switch plugged to dock, sometime working normaly, but many time again only green LED light and no signal. It is not problem of dock, HDMI cable or TV, because all working well with other Switch. USB-C connector of Switch is not reason of problem too, was replaced yet. If Switch in dock started work, it working without problem until Switch sleep or is turned off.
There is second problem with this Switch yet, problem with SD Micro card. While Switch is used, SD working correctly. But after return from sleep mode sometime wrote error, that SD card was unplugged and Switch must be restarted. It is not problem SD card or SD card slot (it was tested with new components).
Have somebody any idea, where on board can be problem, or which components replace yet? Can it be problem of MAX77621? Some corrosion was found near it, but it was not replaced yet, because no shorts. Thank very much and sorry for poor English.
