    Dialog DA9087 PMIC for PS5 controller - where to buy?

    Hi, I have a couple of PS5 controllers that don’t work. After inspecting 1 with a thermal camera I can see that the Dialog DA9087 PMIC is blown. I took the other one off the other knackered controller but it looks to be knackered as well as I only see 0.01a when trying to charge. Long story...

    Hardware 0.45A, No boot - Backlight stays on

    I had another Switch fault today that I haven't seen before and thought I'd share. Switch in question came to me after someone else had worked on it. It looked like someone had replaced the USB-C port at some point and had left a load of flux residue on the motherboard. Symptoms were 0.45A on...

    Hardware no display, 0.42A - possibly a RAM issue

The Lite had no display and once I cleaned off the corrosion and swapped the main ribbon cable around as some of the tracks had burnt out (waiting on new cable) I could get the Lite to boot to a blue screen. Blue screen usually means bad...

    Hardware No boot, slow charge and shuts down after Nintendo Logo

    I've got an interesting fault that I could do with some help on. I've got a HAC-CPU-20 motherboard that was received broken and it looks like someone had worked on it before. I've tried the usual chip swaps (M92, BQ and PUSB) and I've also swapped the fuel guage to no effect. The symptoms are...

    Hardware BQ24193 low VBUS input

    I've got a switch here that has low VBUS inputs on pins 1 and 24. I can see voltage on both pins at the USB C connector (4 and 9 showing 5V either way the charger is plugged in). All the caps around the BQ chip don't show any shorts and most of these caps have around 4v on one side. I've...

    Hardware Righ Joycon R button repair

    The right R button is a weak design since if you break the button off the Joycon usually needs a new board. If you want to try repairing the button and there isn't any pads left on the board to solder to the you can add jumper wire the the pins in the picture below. Hopefully someone will find...

    Hardware BSOD - what are my options?

    I picked up a Switch that boots straight to the Blue screen as soon as the power button is pressed. I wasn't sure if this was Hardware or Software causing the issue so I made a RCM jig and booted up into TegraRCMGUI (first time I'm using RCM mode BTW). Tegra shows the console connected. I...

The joycon's get recognised and pair with the switch however they don't charge when attached to the switch. The joycons also work unattached from the side of the switch. Things I've tried so...
