Blinking cap locks and won't boot

Hi,

The colored line is a bad connection between mainboard to screen ( broken or ripped cable, dirt, ...)

Or a failing GPU.

in case of juice spill , you need to clean the main board immediately with isopropyl alcohol. is it long ago the spill?

try to clean it anyway... but do it propperly , use enough of isopropyl ( you can buy this at a drugstore...)

clean every connection.

This is a good time to clean the fan en colling pads as well. check transistors an capicitators for leak also check the chips on the mainboard. clean the ram would help but i think it will be to late , try with other ram after cleaning.

Most of the time the keyboard is dead to.. replace this as well.

Kind regards,

kevin
