I have 5v on pin 1 of the micro. Maybe I didn't say it right so that is was clear. The only place that the 4.8v is low is on pin 15 & 16 of the micro. If I lift pin 16 the voltage is 4.8v. Bad micro? I replaced it. Replacement bad? Totally unlikely. The measurements are the same as befor it was replaced. jonas miglinas <miglinasj@xxxxxxxxxxx> wrote:Check tuner ic U7401, particularly pins 2 and 3 , see if they are not shorted to ground. Pin 1 of the micro should be ~ 4.8v. That should be the reset and that has to be there.

I have changed the eeprom, have done the tuner wrap,have replaced U3101 and U1001. I have 5v, 7v &12v std. bys as well as 140v. I have monitored pin 5&6 of U3101 and get no wave form when activating the power button. Have checked a ctc175 working chassis and know there should be waveform activity at those pins. Of course no horiz out of the T chip. I have checked continuity to the power button. The clock and data lines look like there is activity however the voltages are lower than the schematic calls for. The 4.8v supply is about 3v on pin16 and 1.5v on pin 15. of U3101. Not sure what else to check ?
