Hi,

Wonder if someone who is an expert can help me.

I have a Philips 42PFL5405H which only shows the top 6 inches of the picture until the room temperature rises above about 20 deg C (the remainder of the display is vertical lines of different shades of grey).

I have tried a new Small Signal Board (the LG TCON i/c is part of this board) and cleaned both ends of the ribbon cables, but no difference (the replacement SSB could have exactly the same fault, but this would be something of a coincidence).

Since the display shows a full width, even when cold, I wouldn't think the problem is the display, but I would appreciate help from someone with more knowledge than me.
