Do i have to replace the main logic board or the power board?
Joey De belen before just going to replace the boards you want to try a bit more troubleshooting. 6 red blinks is a backlight issue. this could be cause by either a bad main board, a power board or bad inverter boards. Try to check the standby voltage on the power board. “backlight on” should be 3-5 Volt from the main logic board and 24V to the inverter. If unsure post your exact model number and some good images of your boards with your question. Use this guide Adding images to an existing question for that.
