The laptop is on MacOS Ventura. I replaced the screen, it turned on for a few seconds then shut down.
It does not take more than .4A at 5V.
Could the new screen have fried the computer?

The new display could just be faulty. Test with the old screen and see if you can get it to power on normally. Even if the screen is not working properly, you should be able to tell it’s powering on and booting normally based on the power reads on your meter.

Hi there,
Thanks for that. Have tried the old screen and same result. The laptop will just not start.
It takes the above values the first time you plug it in, but when plugged in a second time, it will not take any current.
Thanks
@smashedhamish If everything was working properly before the screen replacement, then more than likely something got damaged during the repair. Or the new screen was faulty in a way that caused an issue with the board. I have never seen that happen myself, but it's certainly possible depending on how the screen was faulty.
we had this problem on 2 straight devices, both A2337 running Ventura only take 0.41A, tried old screens, no screen, new screen - same issue. We do 2-3 of these a week so its quite bizarre.
