Assuming you are actually measure the 3.3v on the correct pins and you have a good connection
then if the 3.3v is really 1.35v then no repair is not possible as far as I am aware contacting your supplier is your only option.
but before you do that what happens if you try booting your pi with no SD card installed and what power supply are you using.
Thanks for the reply!
i have used two different power supplies, one is designed for an android phone, rated at 18w, and the other is a rav power 6 port 60w charger.
Both power supplies have powered other pi4's and pi3's successfully.
If i measure the same pins and voltage on other boards and do get 3.3~
When you remove the Sd card and boot without it, the green light is still on solid, as is the red light.
