No video on lcd OR vga

LCD screen cracked, and Three even strips going across? Doubtful. Haven't seen it but I always have my mind open.

Three strips that are irregularly shaped? Look like glass that has cracked?
'Jagged edges'?

LCD screen is broken.

Three even strips indicates to me, that there may be a problem with the Video Cable. Then the screen Inverter is next in the diagnoses.
My money is on the Video Cable.

ALL power removed, Anti-Static Precautions FOLLOWED, I would check out the graphics chipset first.

1) Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port on the laptop.
Left rear side. This is an example of a VGA Cable, and VGA connector. (VGA port on a laptop ),

http://en.wikipedia.org/wiki/VGA_connector

(Color of connector does Not matter. It is generally Blue, though)

You can use a CRT type of monitor, (Looks like a small TV), or a flat LCD screen monitor if it has a VGA cable.

2) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.

There are at least 3 display options available;
1) Laptop internal monitor ONLY
2) Laptop internal monitor AND external VGA monitor
3) External VGA monitor ONLY

Press, and hold down on the Fn key, and at the same time tap once on the F5 key. (The F5 key is the Display Toggle-Over key)

No display on external VGA monitor?
Hold the Fn key down again, and tap once more on the F5 key.

Is the display on the external VGA monitor, the same as the internal monitor of the laptop?

Problem is the graphics chipset.

Display is fine on the external VGA monitor?
Problem is the Video Cable, screen Inverter, or LCD screen.

Video Cable:

A) http://www.irisvista.com/tech/laptops/Toshiba-Satellite-A105/big/Toshiba-Satellite-A105-14.jpg

Switch Cover removed, Keyboard removed. Shows you where the Video Cable plugs into the motherboard.

B) http://www.irisvista.com/tech/laptops/Toshiba-Satellite-A105/big/Toshiba-Satellite-A105-21.jpg

Palm Rest Cover you can see the white rectangular connector, for the motherboard side of the Video Cable, at the top left.
It's above the black cable, and near the screw hole.

The Video Cable leads from the motherboard, up through the left Hinge, and into the Display Assembly.
From there it connects to the screen Inverter, and back of the LCD screen.

http://www.ebay.com/itm/Toshiba-Satellite-A105-6017B0050801-LCD-Video-Cable-Genuine-OEM-Laptop-TESTED-/290754851160?forcev4exp=true&forceRpt=true

In the photo, (You can hover your mouse cursor on it to enlarge), the right side connector plugs into the back of the LCD screen.

The black connector to the far left connects to the motherboard.
The small white connector at the top with the Red, Green, Black, etc wires, connects to the screen Inverter.

(The small Black cable, that comes out from the black motherboard connector, is a Ground wire )

Due to the close proximity of the Video Cable to the left Hinge, it can be pulled on from just normal opening, and closing of the laptop over time.

This means the Video Cable connection on the motherboard side could be loose, or the LCD screen side, or both.

The diagnoses is to PHYSICALLY check BOTH connections. A loose connection at the motherboard, or at the back of the LCD screen could be so small in distance, that you will not see it with the human eye.

Could also result in damage to the Video Cable.
View the Video Cable with the Switch Cover removed, and see if there are any obvious signs of damage to the sheath of the cable.

If there is there could be damage to the tiny wires inside the Video Cable. (Stretched/Broken)

Use a multimeter set to OHMs, to check all wires inside the Video Cable for continuity, or have a 'Mom and Pop' computer store check it for a few bucks, or replace the Video Cable.

Video cable connections are tight? Video cable continuity check checks out OK?
Screen Inverter.

The test for a screen Inverter is to use a sensitive multimeter.
Read fairly expensive.

http://www.fonerbooks.com/test.htm

Not having access to a sensitive multimeter that you can use, means just replacing the screen Inverter. Seems like 'part changing', and it is, but you have to work with what you've got.

http://www.sparepartswarehouse.com/Toshiba,Satellite,A105,Laptop,Inverters.aspx

Find THE model number for your laptop, and the correct screen Inverter. A screen Inverter, and an LCD screen are a MATCHED unit.

Screen Inverter is checked out to be OK, or replaced, and symptoms are still the same, the problem is the LCD screen.

Remember, the first part of the diagnoses was to see if the divided parts were EVEN going across, or jagged and irregularly shaped.

Jagged in shape, and not even strips going across, means cracks in the LCD screen.
Replace.

From your brief diagnoses stated, it sounds like a bad Video Cable.

The Video Cable routes from the motherboard, across one edge of the Fan Assembly, and under the left Hinge assembly,

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-Pro-L450-L455/big-body/laptop-disassembly-19.jpg

With just the usual opening, and closing of the laptop, the Video Cable's sheath may be damaged. This means the tiny wires inside the sheath may be damaged.
(Stretched/Broken)

http://www.laptoprepairparts.com/html/details.asp?ref=1860&category=cables

Or it may be the screen Inverter that is damaged, or going out,

Or the LCD screen assembly.

Could be the graphics chipset.

Diagnose.

1) Laptop OFF, monitor OFF, connect an external VGA monitor to the laptop's VGA connector, on the back of the laptop.

[ RBG (Monitor) port ]

You can use a CRT monitor (Looks like a small TV), or a flat LCD screen monitor if it has a VGA cable, for the external VGA monitor.

[ Example of a VGA cable, and a VGA port (Connector),

http://en.wikipedia.org/wiki/VGA_connector ]

Turn the external VGA monitor on. If a CRT type allow it to warm up.
Turn the laptop on.

By default the external monitor should show the display, also.
IF not;
1) Press, and hold down on the Fn key, and simultaneously tap on the F5 key. (The F5 key is the Display toggle-over key)

Not showing on the external VGA monitor? Perform the above procedure again.
There are several display options.

External VGA monitor also show the same symptoms?
Bad graphics chipset. Replacing the motherboard is the most cost effective method, and easiest method.

External VGA monitor does Not show these symptoms?
Problem is the Video Cable, or screen Inverter, or LCD screen.

Due to movement of the LCD screen, which means movement of the Video Cable, my money is on a bad Video Cable.

(A Video Cable can be unplugged partially, real easy, on the back of the LCD screen.
It MAY look plugged in tightly, but may not be.

It can also be unplugged real easy when assembling the Display Assembly, to reinstall back on the laptop )

Check the Video Cable's wires with a multimeter. Perform a continuity check of all wires in the cable. (Multimeter set to Ohms)

Have an assistant also gently wiggle the cable, as you are testing. See if there is an intermittent break, due to a stretched/broken wire.

Or just buy a replacement Video Cable, and use it.

sounds like your screen inverter has stopped working.

You need a new keyboard. The sugar in the soda caused the damage and will further corrode the keyboard.

I would also recommend that you clean the area where the soda may have spilled to on the system board.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response

Thanks, Joe

In order to check what is really not functioning. Your laptop have a video port for external monitor which is color blue often at the lower back of your lcd screen or at the side. Plug the CRT or LCD monitor to your vga(video graphics adapter) port to check if your laptop is still functioning. If there is a display on your external monitor that means you have to replace your lcd monitor. If there is no display with external monitor check your memory or ram by unplugging your memory then clean it with a hard eraser the memory pin and then put it back again and turn on your computer to test if already functioning. If the above procedure didn't work you have to bring it in a computer repair shop. Have a good day!

I had the same issue with my laptop after I upgraded my video driver. Check on the Toshiba website for the correct display driver for your laptop and download it. Follow their directions and install it on to your hard drive. If it is the same driver that came with your laptop originally, the default settings should allow you to connect back to your LCD TV and get the proper display. If that doesn't work you will probably have to call Toshiba support and ask them for the default settings.

It is likely the only problem is that the soda is causing the keys to stick. There is probably no damage to any other internal components. Usually, laptop keyboards have a metal-based frame/tray that will protect the internal components from minor spills.

If you want to get rid of the cracking sound, you'll need to purchase a replacement keyboard from the laptop manufacturer or another source such as eBay, and then remove the sticky keyboard and replace it with the newly purchased one.

Every laptop has at least a VGA (computer video connection) and s-video cable port. A VGA cable is preferred if you want to be able to read text on your LCD TV. Check to make sure that your LCD TV has a VGA connector. It's a port that accepts a 15-pin connection so it's pretty easy to spot if it's there. It's just like a computer monitor cable if that helps. Should be able to find it at any local retail store that carries computers. VGA or RGB cable.

Hard to tell without opening the laptop up. Depends where the soda got to. Alot of times it could be an inverter ($70-$150) or could be more serious like a new LCD Screen ($400+) and/or Motherboard ($$$+).

I would take it somewhere you trust that has a small diagnosis fee so they can take it apart and see what the soda has gotten too. Then you could decide if the cost is worth it.

Hope this helps.
