Sony XBR49X800D ghosting on bottom of screen

[k0nsol]

Good afternoon!

I have a Sony XBR49X800D that is ghosting on the bottom half of the screen. The top half is perfectly fine.

I've replaced the TCON, and all three cables (one from the main board to the TCON, and both ribbon cables from the TCON to the LCD Panel), but the issue still remains.

If I remove one of the ribbon cables, half the screen (left or right) goes white, but the bottom half still has issues.

Would this be a panel or main board issue?

the horizontal line on the right is likely a "panel fault". Either the tab or connection to it is bad. Depending on the design, the tabs on the side may be removed to "save" the set and return it to "normal". Otherwise, alternatively, if there are no side tabs, then the "tape cutoff" method might be used at the tcon to panel connector to isolate the offending connection.

It would take some time, but the cut-off method using apiece of stationery tape should fix this problem. Start with a 1cm wide piece, letting it fold over on both sided of the FFC. Usually the RIGHT side looking from the back of the TV is the side that gives the problem.

however this LCD it had side band.. but the horizontal line are exact at the middle, its picture flip down, since this is Android TV the reason of Flipping Picture could be caused of many parts fault either the LCD self.
the wise way only to judge this fault you need to inter service menu... or go direct to diagnostic mode to check if any error registered.

Check the little capacitors on tcon for shorts, diode mode, tv unplugged.

The TCON was replaced, but it didn't change anything . I'm thinking it's probably the panel as suggested.

What do you mean by this? Google didn't shed any light on an "FFC". By this do you mean the cables that go from the LCD panel it's self to the buffer board?

FFC means Flat Flexible Cable. Sometimes they are called Ribbon Cables. No, the FFCs that go from the T-Con Bd to the long panel Bds. They are usually white or cream coloured.
