I think you have a ADC that went bad and needs to be checked out. You need to have a service adjustment done by your Service Tech. You just can't fix the ADC without clearing the buffers, and all the other procedures needed to fix this TV. I think your TV repair persons are probably just going over the complex procedures to fix your TV.
Good luck and have a great day!
