I recently order a new power supply board from 'shop jimmy', and while not an experienced tv repair guy, I checked all the numbers and parts on the board. I went to unscrew the old one and put this one on, when I realized there's a pin connector cable that goes from a 20 pin on the main board to a 16 pin on the power supply. On this new board that jimmy sent, it has a 14 pin connection. I don't solder, so can I get a connector cable somewhere that's 20 pin to 14 pin that will work? Or do I need to somehow get a 16 pin female connection on the new board
You need the correct board when ordering replacements you need to quote all the numbers on the original often on a separate sticker on the board as there are often many versions with same board number

I have a feeling that the main board is damaged since the protection Diodes are blown, it may have taken out the processor.

Some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.
