Your Model # is KV-35S42 and most likely you have a bad picture tube......you might see if you have a de-mag problem..
ask a local repairman to de- gauss the tube...
Was the TV moved / dropped ?...................................T.

Sony Trinitron picture tube


The correct box will be supplied for your set through the cable or satellite provider-No problem there, but what do you want with a 5 year old set other than placing bets on what will go out next? A pix tube is not cheap nor good insurance against future problems...accordianman
