Will I be able to get a second exchange on my faulty camera?

Nearly 2 weeks ago, I got a Panasonic DMC-F3 digital camera, and after 2 days some black lines started appearing on the screen (even though I have never dropped i and has never come in contact with water) and then started growing into 4 spots (circles) so I took it back 4 days ago and got a replacement but then guess what? The SAME THING happened to the new camera! It had exactly the same problem, black lines and spots on the screen, and today I went to check up on it and the WHOLE screen was green (the camera was off) so I tried turning it on and nothing happened. And I got the battery out, put it back in, and now it is not turning on at all. I'm on a 3 year warranty.

So my question is will I be able to get a SECOND replacement and can I get a different brand camera eg. Canon, Nikon. Or can I get a full refund and then buy another brand camera.

Keep on exchanging until you get a camera that works, or until you decide to get a refund and get another camera.

If you like the camera you chose, refund it once more. If it does the same thing, just return it and get a different camera.

As long as you did not cause any damage, the camera is under manufacturer's warranty, protecting you against defects.

Well perhaps you should take a lesson here, yes exchange it but don't do Panasonic, do Canon or Nikon.
