Sony Bravia KDL 46z4500 display band

[andyturbo]

Just picked up Sony bravia KDL 46Z4500 which has a problem showing on display as a band on the second quarter which only appears after TV has warmed up for about 20 minutes. Have stripped down display to check ribbons, tryed swapping ribbons to see if ribbon problem, but no change. Pushed tabs to see if any change but no. Nothing else appears to be obvious, I have concentrated on the tcon area, ribbons and tabs so far, as this seemed the obvious area to me.

Any input would be appreciated, perhaps someone has had the same problem, many thanks.

Looks like another bad LCD panel to me. Can't really imagine anything else causing it.

Thanks for reply. Not good news. Thought might be something else because only covered one quarter of the screen, but accept this could be the case. Many thanks.

I admit, it's a little different to previous bad panel artefacts so it might be worth trying the T-con board. What is the part number for your T-con... I may have one in my pile.. think it might be from a 40" W4500 but might fit.

Checked my pile, no match I'm afraid.

Not sure who made panel labels under board at present, but serial number is SO1-9003796-k

It will most likely be a Samsung panel.

These Samsung panels, suck big time.

Update on screen display fault. Finally located a replacement tcon and fitted, all seems good, no display band or any other related fault. So it seems it was the tcon at fault. Thanks to all replies.
