Yes,
the cables certainly look suspect.
I have never encountered this connector before.
Can someone advise me on how to remove this.?

big time ugly... that looks like some form of water ingression / contamination. hopefully, it can be cleaned / checked.

iirc, you press down in the middle section which causes the outer two edge points to lift a bit. Hopefully, someone will know for sure. Don't force things though as finding replacement cables can be tough.

yes,pressing the cntre allows the cable to slide out.
Both cables loss of connection.

I hope this means you have the new cables ready. Depending on how bad the old ones are, you might just consider tossing them... just in case playing with them any more might take out either the tcon or main board.

Hi bud,
yes I expect the replacements tomoro to arrive.
It must have been corrosion as I didnt see anything odd under the micro.
Tv powered on with no cables shows this cycling as well ..So most likely was the issue.
I will update once they arrive.

By looking at the middle of that connector it looked like it shorted, arced, and burnt through the white plastic release. You might have to replace the main and the cable.

Hi guys
update on this.
replacement Cables were installed .
The indicator led then went from green alternating to yellow and the same intro music being played but NO backlights!!!
I then inserted the USB with the update.
This time the USB light blinked for a much longer time than the previously attempted update.
But then after approx one minute,the mainboard light went out.
Now the indicator led is flashing white .

upon closer inspection of that connector,that black soot mark rubs off so no damage to the connector.
No damage to the plastic that would indicate heat of any kind.
