Multicolored vertical bands means that the contacts on LCD ribbon cables are still shorting because of liquid or oxide building in consequence of liquid damage.

Also keyboard is probably not working for same reason.

When you get liquid damage you need to remove immediately the battery and the ac charger, and service the laptop, to prevent more damage caused by shorts.
The service is done by a technician, disassembling the laptop and using a cold hairdryer from distance to dry internal parts.

You must ensure the laptop has no liquid inside before starting it.

In your case I can only tell what parts are working:

If you can see the vertical bands and there is no static stain on display caused by liquid penetratrion, then the LCD is working.

You have backlight, therefore the inverter is working.

To connect to external monitor you can try starting the laptop with video cable already connected, It should start on ext. video.
If you are getting video signal on external monitor, that means that the motherboard is still working.

If you also get windows splash screen (or Linux) , then the hard disk is also fine.

If you do not want to spend any money for this laptop you can wait few more days, with battery out, and try starting it, in the meanwhile oxide can cause more internal damage, that is not the right way to proceed.
The laptop should be sent for repair.
If the laptop is less than one year it will still have factory warranty. However, factory warranty does not cover liquid damage.
If you do not mention that there had been liquid damage , they will probably not realize, and cover the repair, but that won't be really fair toward manufacturer.
To do things properly contact manufacturer and explain them what happened , so that you can arrange a repair, if laptop is fair new they will make an effort to keep quote low.

Do not forget to leave feedback.

Can you do a hard restart on a Katana II?

You can do a hard reset on the phone which will erase everything but you have to know the Master Subsidy Lock code on your device. If you can't turn the device on that will not work though because you have to access the Erase Tool from the menu while the phone is on. Have you every exposed it to any kind of liquid or extreme physical damage? If the device will not charge the battery, it sounds like you have a loose charging port. Take it to the Sprint Service Center and see if they can issue a brand new battery and check to see if there is physical damage to the port.

Lines across the LCD screen

Two things can cause lines across the LCD either horizontal or vertically. The first (and most likely) is a small crack in the display wafer. LCD stands for Liquid Cristal Display. They are very fragile and can be easily damaged if dropped. I broke one in my pants pocket.

The second would be if a pin on the ribbon cable (to the LDC wafer) was not making good contact. If you disassemble the camera it is possible to clean the contacts using contact cleaner (or alcohol). Only attempt this is you are willing to replace the camera if you don’t put it back together properly.

Dropped my cell in a cup of soda!!

You dealt smartly with liquid dropped cell phone. Water and salt badly effects cell phone's battery and display. You have samrtly saved your phone but i must say that your effected display is ruined and needs to replace. You can replace it by contacting skilled techncian near you. There is not another way and i m sorry to say that. Ask fixya for servicemen arround you.
