Chosen Solution
Have a MU8000 series TV that only shows color bars. There is no picture just Color bars. Already replaced t-con so I suspect it’s the panel but before I throw the TV away I wanted a second opinion.
jrgrade could be the gate drivers on the panel but you do want to check your cables and make sure that they are connected and inserted properly. Check all the pins and the board connectors as well. Before writing that one off I’d be trying a new main board first. Buy it from a place that has a decent return policy so you are not stuck with the board.
