Regards medar58, I have the same team with a very similar fault. Could you solve? I have several days turning it around. This began the same, after a while of normal operation began to show interference and skip channels until it only tuned to a single channel, specifically 14. If it turned off and left for a few hours unplugged it worked fine another time until it failed again . Change the tuner and the fault persists so I presume that the fault is in the logic, probably the micro. I will create a new question with data and photos as detailed as I can to help me.
