Before replacing a board or a panel, check the physical jumper header labeled . 32-inch panels typically require 5V . 40/43-inch panels typically require 12V .

Stepped-up voltage can be measured at the cathode of the secondary boost diode. If this matches the 12V rail exactly while the TV is "on", the boost circuit is not switching.
