Troubleshooting • Raspberry PI 4 - Screen goes blank after start.elf message

Hi all.
I have been using raspberry pi 4 for quite a while to display my calendar to kinda remind appointments, classes, reminders for eh whole family.
Recently had a little accident of water spilling on the unit and think was quick enough to pull it out and dry it.
After that I am not able to get the unit and display working at all.

Tried the following over course of completion of months.

1. Dried it in open air and also inside a rice container.
2. Tried to insert the old sd card and the problem started.
3. Tried to switch between couple of sd cards and all the same result.
4. Tried switching the boot preference from sd to flash drive and same result.
5. Tried writing 32 and 64 bit os from pi imager. Results the same.

Have been using pi imager for all the writing of os to sd card.

The latest log is attached as screen shot and this is what I managed to capture before the screen goes blank.
Please do suggest what am doing wrong here or is there any way I can make it work?
Thank you in advance.
