When booting up my Dell Inspiron 1520 laptop the screen flashes red a few times prior to settling down. Then there is a noticeable amount of excess red tint on the display. What is causing this? What are the steps to correct it? Thanks for any assistance.

Did some research via Google and people with this problem pinpoint the inverter as the main culprit. And your issue of the red tint being really noticable when you first boot the system matches the description of others who had a faulty inverter. If you have a warranty on the machine I would call Dell so they can replace the part (they'll replace the entire LCD screen and not the inverter). But if you don't an inverter is usually pretty economical and not too hard to install yourself (if you're up to that).

If the red tint appears at boot up with the external monitor, the problem lies with the GPU in the DELL.

If the red tint doesn't appear at boot up with the external monitor, the problem lies with the inverter / lcd itself.
