Dropped Steam Deck - Broke Left Daughterboard

I dropped my steam deck and the LB quit working. It appears I broke the little blue piece that the LB makes contact with to produce the clicking noise. So I believe I need a new Left Daughterboard, which iFixit does not sell. I have attached pictures, sorry for the quality. Valve has still not gotten back to me after a couple of days. Can anyone verify that I need a new daughterboard? Does anyone know how I can get one? Or does anyone have any experience/advice with this? Any help is welcome. Thanks for your time. I'm beginning to worry there isn't a fix....

it just needs the button replaced, you would need to get someone to be able to source a suitable replacement and be able to solder it on to the board

@spocksbrain how exactly, does the posted photos not show a broken button ( yes ) is a button replaceable ( yes ).

@tech_ni Love how there is no explanation, just "you are wrong". LOL!

@betatechlabs yea 2 years and still no answer to why im wrong even tho iv done plenty of repairs like this and more difficult repairs.

the daughterboards still are not in stock and i suspect they sell out instantly whenever they are in stock. that fragile flimsy microswitch is the number 1 most broken piece on this hardware.

Hi, there are compatible switches e.g. on aliexpress. look for "Steam deck button/switch" or "XBOX 360 pair switch". A smartphone repair shop can swap the switch for little money

@dawid68075 you will probably be wrong aswell as i was for saying the same thing

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

@tech_ni I overlooked your answer :D we both are wrong, lol

iFixit does have the part listed, but it's currently not on sale:

Currently I have this problem too (although the switch did not come off of the daughter board)

I ultimately decided to RMA the deck.

what does RMA mean?

Hi,⏎
The 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.⏎

Hi, this is most likely a linear hall sensor or some other kind of magnetive resistor. I do not know the part name/identifier, unfortunately
