Where I can get instructions that how to replace Sony VGN FW170D display? and best web site to buy display. I gotcrack in my display, only half of the display works.

You can find basic instructions for the display at:

The instructions are for replacing the LCD bulb or the entire LCD.

As far as an LCD goes I go to eBay to get many of mine. Belive it or not if you can pull the LCD and get the brand and model number of the actual LCD you may be able to find one easier than going by the model of your laptop (sometimes). You may even save money by looking by LCD model rather than Laptop model.

Hope this helps...
