when i plug in a hdmi to any one of three ports i have no display

dannymesser18 could be an issues with the HDMI selector IC (IC6600). You do want to check the following if you have no HDMI input HDMI1 Terminal - IC6600 - IC5500 HDMI2 Terminal - IC6600 - IC5500 HDMI3 Terminal - IC6600 - IC5500 Parts: Around IC5500, IC6600

If nothing else, I’d replace the J4FK mainboard. You can get that from places like this and a few others.
