Need ribbon cable from power board to main board for a 75S423 TV

Hi @roberthasson

Not sure which one is the correct one, but here's a link to the parts for the TV that may help.

Scroll down to find the 2 'wire" cables available. Searching online using the part numbers only gives 2 suppliers (the one linked and only one other) but the cables are both shown in the search as ffc cables (flexible flat cable) which means a ribbon cable.

Perhaps contact the supplier in the link and ask which is the power board- mainboard one.

If you still have the cable (is it damaged?) there may be a part number on it that may help to identify it.
