Samsung UN55KS8000F Part ID please.

Kilroy2k1 · 08-31-2020, 06:44 PM

I'm working on this 55" KS8000 that has the power cycle issue. I've managed to trace the fault to a component on the left most (when viewed from the back) buffer board.
As per the pictures attached the component is marked 4263H and its silk screen number on the board is D005 so I assume its a diode array of some sort.
My google-fu has failed me so I'm turning to the pros, would anyone be able to identify this part?
Thanks.

So does the TV power cycle if the cables between T-CON and the LCD panel are not connected?

Yes, if any of the lvds cables are disconnected it will do the power cycle. I did trace the short down to that one component and removing it brought the tv back to life but i'm not sure if it can be causing any damage by not having that part there.

Hello everyone.
I also removed the exact same thing. Would there be any problem after removal?
Originally there was 4263H, now I found 6514P 2015 (2019)
I just don't know if it would be possible to replace it.
Thank you for your response
