Title: Ceronix 1793 Post by: drakejd1977 on January 18, 2013, 04:14:02 AM Ceronix 1793- I hear the high Voltage pulsing but the monitor will not come on. I have done a complete cap update, Changed 115, LA7838, 423, 460, LM324N, 296 and 181. All caps are in correctly. Has anybody seen this before?

Check Parts 477 and 478 in the flyback circuit. I have seen them short. They are HER208 Diodes. Title: Re: Ceronix 1793 Post by: drakejd1977 on January 24, 2013, 01:46:18 AM They were not shorted. i even changed the CPR0501 circuit board still doing the samething. I even swaped FBT.
