Sony KE-32TS2U. Need any advise I can get on this problem. The colors are, as best as I can describe, mottled. Take a look at the attached pictures. It did something similar before under warranty and the power supply was replaced. Would like to get second opinions before I buy the part or should I simply bend over and have the Geek Squad handle it? Thanks for any help.

Note: I just looked at the pictures and they were too small to tell anything. I've loaded new ones. Sorry.
