Introduction
Use this guide to replace the right trigger assembly (R2) on your Steam Deck LCD. Although nearly identical, the procedure for the left trigger (L2) can be found here.
Remember: follow general electrostatic discharge (ESD) safety procedures while repairing your device.
Replacement triggers require calibration to work as expected. Read about how to do that here.

The shield doesn't need to be removed for this repair. The trigger is difficult to replace. Start with the outer peg first, leftside, and then position the right-side above the peg. Apply pressure to get it over the leg, then continue pressure to get it on the peg. A little tricky, and don't forget to attach the spring first.
My transistor on the left daughterboard is missing. I would like to buy a new transistor and solder it myself. Could you please provide me with the specifications of the transistor or give me a link to purchase one? The L2 button is not working because of it. It has the code "303" on it, you can see it in the images above
