Sony vaio Screen dark and undereable

The screen is visible, but barely.  My online research and conversations with local CPU repair shops lead me to believe it is either a backlight bulb, an inverter, or both.  It might even be a wire issue.  The CPU was damaged on a flight so it could have been from air weight compression or extreme cold.

"Dark, but barely visible" is almost always a backlight issue, and that almost always means you will need a new LCD panel.  Check with Sony to find out if replacing the LCD panel itself will also include the inverter.

I have replaced countless Dell, HP, and Gateway laptop monitors for this exact situation.

from experience when the screen is barely visible then it is a back light issue. If you have an extenal vga port and a monitor try and plug it in. That way you can verify the hardware excluding the screen can be tested. If all works then it looks like a replacement screen

If you are confident that you can replace the screen yourself, then places such as ebay can be a good source of working second had or even new screens at a reasonable price

you can find PDFs and walkthrus on changing out the LCD and other parts of your laptop.  and i agree with cwstad2--ebay is a good place to buy used parts.  

depending on how the "CPU was damaged" I'd still lean towards the backlight being out and replacing the LCD panel is your best bet over the other options.

It's most likely the inverter. As those are relatively cheap and easy to replace, you could open the cover with the display and check the inverter's exact part number, and then search for it on ebay. I've hardly ever had the backlights themselves break, and when, only if the bulbs were removed from the panel carelessly. With many panels the backlights are also hard to replace and you risk damaging the LCD panel too. So if after replacing the inverter you should still have the same issue, I'd either think of selling the PC on ebay as a spare part repository, or try getting a complete replacement panel.

your first course of action would be to see if the issue persists on an external monitor.  if not, then the problem is definitely the LCD panel itself.  If it is on the external monitor--as unlikely as it is--is a motherboard/video card issue...and that's a horse of a different color.  post back and let us know, along with the model number of the laptop.

assuming the external monitor works, you should contact Sony Parts Dept for a quote on how much the LCD will cost and also find out if that includes the inverter.  it is highly probable the issue lies in the backlight, which will come as part of the LCD panel itself.  a much lower possibility is the inverter board has gone bad--but which may or may not come with the LCD panel.  
find out and go from there--be sure to check ebay and craigslist in your area.  

google    Sony Vaio [model number] teardown    and you should find some helpful information on how to do this work.  i can offer tips on the hardware side if you need help...

If you are going to replace the LCD, make sure you get the exact same part number as what is in your laptop. Many Laptops have different displays for the same model, and usually you can't interchange them, as they need a different version of the mainboard or Graphic card, or need to have different dip switch settings, that are usually not released and therefore unknown to the public.
