no power to thermostat connector on circuit board
my circuit board in my unit burned up and i replaced it. i am not getting any power to the red wire terminal that sends power to the thermostat. I can jump power from the low voltage wire from the transformer and it will work

What do you have between these 2 points?
A fuse? float switch? duct mounted smoke detector? zone control board?

no led lights, the low voltage from transformer plugs into circuit board, goes through many different resisors and stuff, cannot follow, but no power getting to the power terminal for the thermostat on the board. the board is a ICM276 fan blower control

Are those the X and C connections ?
Can you tell me what the 5 terminals are labeled as.... T7=? , T4=?

Looking at the remarked board..... you need something to close the R to X jumper at the plug. I don't know what you have.... maybe a safety switch is open.
