There is an IC that translates key-presses into a usable datastream and it may be part of the keyboard assembly since many of them come from a few manufacturers. The spill has either disabled or damaged that chip and unless you are adventurous and want to try removing it and bathing in distilled water, allowing it to dry for several days, you will have to have it replaced. DIY may not cure the problem anyhow as the chip might have been damaged as mentioned.
This shouldn't  cost more than $100 US to replace; the keyboards cost likely under $10 US from the original maker.

Infrared on all the time sony remote

Hi Robert,
Most of these remotes are carbon pattern type closed switches. If you cleaned the PCB with other than a real pure solution like rubbing alcohol the pad may still be shorted continuously. The real problem is that if the button were sticking that usually mean there was a contaminant inside the remote which could be a drink or other spill. All that needs to be cleaned out. I use denatured alcohol but I do not scrub the carbon traces as they can be removed if not careful. A light cleaning with Windex might help as drinks are water based not alcohol based. I could take a look at the remote if you want. I repaired a number of them when I was Sony authorized and working at other places as a Chief Engineer. People seem to bring me things to repair- it is still going on but most cassette decks and Open Reel decks now.
E mail me at if you need help.

Hi Tim.

so (windows 7 ? here"?
go to control panel, go to device manager.
then see is the keyboard driver is not bad. (marks on it)
sounds like a bad keyboard
you can in fact unplug internal keyboard cable (ribbon type)
use what you just did the virtual keyboard test.
then plug in a every day, usb keyboard and if that works
the internal is bad.
it will not be the first keyboard to fail, ever
the get spilled drinks on them or just wear out.
its now 8 years old.

the nice thing, is that uSB keyboard might last 8 more years.

I think that my blackberry cuve may have a little bit of water damage because someone spilled a drink on it last night. I took the battery out and put it back in and the phone comes on and the messages are...

First, to check if there is water damage inside the phone, you can check the water mark sticker.
When you take the back piece off your phone, on the left of the battery inside a rectangle shaped cut-out in the plastic, you will see a little square. If it is red/pink this means there is definitely water damage, if its white then no water has reached that part of your phone. Unfortunately if its turned red or pink Blackberry will not repair it free of charge.
That being said, you can try completely submerging your phone in a bowl of rice. This will draw the moisture out and hopefully get your phone in working condition again, this has worked for myself and many friends.

I spilled some 7up on my dsi, my dsi's R and L buttons weren't working and so my cousin ripped them off(against my orders) So i spilled the soda on it, without the R and L buttons. Now it won't turn on,...

the problem is this, the liquid you spilled on it has gotten into the panel and has therefore caused a real mess of both your panel and device.this is common to all electronic devices, the only way out is if you can take it apart carefully and try to use a piece of cloth soaked in methylated spirit to wipe the entire board clean(methylated spirit dries faster and evaporates other liquids like your 7up which is probably still on the board causing damage).if this doesn't work, the only way out is to give it to an engineer or call the company because the liquid might have caused a short circuite and damaged the whole board beyond repairs.

My shift buttons are not working. sometimes they

More than likely, someone spilled food or drink in the keyboard. Take the keyboard turn it upside down and shake vigoriously. You'll be suprised of the stuff that comes out. If that doesn't do it, purchase a can of air, and turn the keyboard on it's side or slightly upside down so the stuff can fall out of it, and give it a good blow (with the can of air).

Have you spilled a sticky drink like fruit juice on the control panel? that often makes the buttons stick 'in'. If they are stuck, you might be lucky and free them with WD40 - but often panel will require stripping down and cleaning.
If not that, needs investigation by an engineer.
