I have a macbook pro 15 inch mid 2010, and upgraded to 10.10.3, and suddenly started to have parallel black stripes on my display, what is going on?

Try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear and again when you log in. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don’t do them all at once.

As strange as it sounds, the problems you describe have had a correlation to OS X upgrades. They seemed to have been more of them with Mavericks, but additional reports began to arise coincident with Yosemite.

Only Apple can make a definitive conclusion regarding that particular hardware problem. They have a specific test for it.
