Hi: Is the power supply IC the same in all the CTC 169? I have no regulator start,raw B+ ok.Changed all the 4 caps and U 4101 and the chopper output tran. The supply is not in shut down. I have only 5.3 volt on pin 15 and 16. I also changed R4105,C4107 and R4003.The only thing I can think is that I have a bad IC.Thanks barrystv@xxxxxxx Barrys TV Ottawa Canada ----------------------------------------------------------------------------- Lost Password: http://www.tech-assist.org and select "Login Problems?".
