Is unfortunate its putting up such a fight.. Was there a way to test the voltage regulator/transistor? Looks like another low cost component.. Maybe you can check for shorts on the coils in the flyback? I've never checked one.. It would be better if you knew with certainty that was the issue.. Replacing everything w/o knowing who is causing the issue is likely to create new problems.. But you've been living it... |

I have the extra parts. It wouldn't take much to change out that voltage regulator transistor as well. When I remove the Flyback I will definitely check it out the best I can. It would be nice if it could be repaired. I'll include some pics if there are any visible signs of damage. Worst case scenario, I replace the flyback with a A29951B and modify the horizontal width circuitry with the correct value combination of chicklets. I'll keep you posted. |

Looking good... :cheers: |

Good morning all, quite an eventful weekend. I had a chance to replace most of the caps from the cap kit that I ordered. I would have replaced them all, but 7 of them from the kit were incorrect. See Pic below. A couple examples: My C303 cap had a value of 10uf @ 250V, the kit supplied a 22uf @ 50V replacement. My C504 had a value of 1uf @ 160V, the kit supplied a 1uf @ 50V replacement. The list sheet stated a higher voltage would be ok, but not a lower voltage. See pic below for full original values and supplied values. I’m going to try to contact Arcade Parts and Repair today to try to exchange the incorrect valued caps for the correct ones. The blue dot on the sheet below indicates the caps that I was able to correctly replace. I’m just noticing that I’ll have to un-solder C408. The replacement cap voltage is too low. I’ll double check all the polarities before I move on. Additionally, I was able to un-solder the Flyback. I flipped it over and took a picture of that as well. See pic below. I would have taken a reading of the coils, but I don’t know what the values should be. I also want to check out Resistor R908. One of the links I read said to check the value and replace if necessary. I feel steady progress is being made. Still much to be done. Any thoughts? |

See Pic below shows underside view of the Flyback. |
