No its not normal but I have to admit Ive never seen this before and Ive been working on TV's since they were vacuum tube sets

If you go into the menu there should be an option to change the brightness and sharpness of the image

Picture tube is weak. You can add a booster the Picture tube. I would replace the set.

The pictures are indeed negative.  When scanning negatives or transparencies make sure you have the scanner set to the appropriate setting, otherwise simply Invert the colors in Photoshop, or similar photo editing software.

I changed my lamp in the 65dr650 but the picture still looks like a black and white tv and flickers

Often you will get a bluish or reddish looking picture if your wires from your cable box/satellite or DVD player are inexpensive RCA type video cables. Try using a nice set of component cables or HDMI cable from your sources to your TV. If this is your setup, try this first...its the most inexpensive first option.

Yikes, I have never heard of the set looking like a negative before. What model# do you own?
