Sony KLV-32 ex-500 Horizontal Flicker/discoloration

[Chaks]

Sony LCD TV has horizontal flicker/discoloration stripes/bands across the screen (see pictures in the link).

I have disconnected the TV from all inputs and opened images from USB Pen Drive. But the flicker and discoloration still exists.

The OSD onscreen text and symbols are clear and discoloration free. There is a slight flicker in the text if we watch it very closely but at 2-3 feet and beyond it is not notice-able. The OSD being clear and proper colored can I assume that the LCD panel is OK and there is some issue with the other electronics.

Is the discoloration due to bad Power board or Tcon board or the main AV board.?.

Usually what causes such horizontal flicker and discoloration?

Thanks a lot for your time in going through this thread.

Look at everything at the left and right sides of the Panel edges, using a magnifying glass. See if there is any discoloration or dirty spot/s formed inside the glass edge/s.
