You need to check that the correct standby voltage gets from the power board to the mainboard OK and that it is steady.
Looking at the flow chart it appears to be +5V DC. Hopefully it will be marked on the power board where it is. Look near the connector where the cable that connects the mainboard to the power board is connected. It will be designated something like STBY and a voltage value.
'''Be safety aware''' ''when working in the back of a TV as there is'' '''exposed lethal AC voltage''' on ''the power board. Disconnect the power from the TV unless you need it for testing purposes''

The part that you mentioned that looks scorched could possibly be a varister. Is it near to the mains supply input at all?

Does the scorched part only show a DSC 5 -15 as I could only find DSC 5D-15 thermistors? Is it near to the mains supply input at all?

Also post a close up image of the power board. Here’s how to do this on ifixit [guide|21499]

If so check what markings are printed on it so that its’ value can be known. Be careful not to rub it of with your fingers as can sometimes happen when touching them.
