Hi Tech's, I have asked about this tv before. It has no reception only snow on all channels. When I check the tuning voltages the TU pin never changes always stays at 33 volts. From what I can tell the tuning voltage comes from inside the tuner being controled by the micro through the data lines. I have replaced the tuner 2 times thinking the first replacement was defective. I do not have the exact schmedic for this one so if anyone has seen this before any help would be a great help.
