I bought a Mits through Sears and one primary reason was the quoted great warranty plan. They said if anything, ANYTHING, went wrong with the set I could exchange it down the road. This included cosmetic damage, power surges, etc. I ended up returning the set for other reasons, but when I read the warranty agreement in detail, it explicitly excludes ALL acidental damage, power surges by lightning, etc.! After speaking the the General Manager and he verified surges and cosmetic damage weren't covered, he asked for the names of the salesmen that quoted me the false coverage (which I promptly gave him!). At least I got someone in trouble for all my grief!
