MacBook Pro water damage short circuit

[Tregwizard]

Hi,
Unfortunately I recently spilled water on my MacBook Pro 2019. It has the following specs: https://business.currys.co.uk/catal...2019-intel-core-i7-512-gb-space-grey/N280920W .
I only spilled a few drops of water on it, landing around the keyboard and touchpad. I immediately turned off the computer and left it closed with the keyboard facing down and placed it in the airing cupboard. Unfortunately I didn't remove the battery and didn't use any paper towel.
I kept it turned off for 5 days and have just turned it on. It appeared to be working OK. It boots normally and will then run completely normally for a random amount of time (usually sub 10 minutes and frequently much less) and then it appears to spontaneously short circuit and cuts power to the screen and/or touch bar. The computer remains turned on at this point. If a second screen is connected it loses power to this display, so it appears to be an issue of power rather a problem specifically with the MacBook screen.
What would people recommend? I'd be very grateful for any tips.
Thanks.

The second screen (monitor) is not powered by the MBP, it should have its own power source. Apparently the second screen loses signal, not power? Or it has signal, but the signal is a black screen?
Not that this helps solve your problem, just trying to better clarify the symptoms.

I'd look into getting it serviced by a reputable repair clinic. Since everything is booting, your SSD controller isn't fried, which is the real issue with these (high voltage line is mm's away from unprotected! SSD controller's low voltage source). In all likelihood a good ultrasonic cleaning and replacement of whatever is shorting will bring it back to typical room-heating function.
