Facing TV Problems? Ask a TV Technician.
I'm reviewing your details and will reply shortly.
What we need to know (since the issue occurs on all Inputs- we know it's internal, it's now just a matter of finding out what internally is causing it), is IF the MENU always displays perfectly pristine and normal over the affected issue, or when the lines and blur occurs- if it also affected the MENU. Also what device/source are you using on the TV- have you tried another source like a DVD player? Also have you tried more than one HDMI cable?
Okay. This does indicate a hardware failure in the set- with the two common culprits being the "T-con" board (LCD timing controller), or the Power Supply board (which has an output that feeds the T-con). There are however no pushbutton fixes for this and it does require service. That said, were you looking to attempt to repair the TV yourself, or were you looking for a repair estimate and service locator?
