    Switch Lite liquid damage-no power

    Hello all, I'm diagnosing a Switch Lite for my friend and found liquid damage that corroded the capacitors around the BQ24193 chip. I'm not 100% sure if the chip is actually bad yet, but I did find a shorted capacitor (image with red arrow). The short is still present with the BQ24193 chip removed and I unfortunately also found that the corrosion took the lives of a few capacitor pads as well as half of one of the chip's.

    What do you think? Is there any chance at repairing these pads? Also, I'm not sure where to check next since the short is still present for the capacitor when the chip was removed.

    Its not too bad and you can always run enamel/ jumper wires to where it needs to be. you should write the diode values down on picture to get a better idea. I used this guide for better understanding on the switch, its for first gen switch but can give you some path to go.

        Micro Momentary Push Switch?
        by Natob82
        Great to be here! I'm a newbie here trying to find a "micro", momentary push switch to repair a Sony "clamshell" video walkman. This micro switch has long since discontinued by Sony, however I hope there are third-party switches of the same size and functionality that I might be able to source to play the same role. The purpose of this switch is to tell the video walkman that the user has activated the mechanical tape eject button, turning that physical action into an electronic signal that tells the tape transport mechanism to open so one can load or eject a video tape. I...

        NEC TurboExpress On/Off Power Switch Replacement Help
        by grimacelord
        Hello,

        I've been working on a NEC TurboExpress and I accidentally got the plastic inside the power ON/OFF switch too hot while doing other repairs and melted it. At first, it would still power on when sliding the switch, but you had to really press inward while sliding to get it to work.

        I removed the switch component and tried to gently melt the plastic back so it would work more reliably and all I managed to do was make it worse.

        I need to find a replacement On/OFF switch for this, but having some trouble figuring out which kind of switch I need....
