    ive read around on these forums and have gotten the feeling that nobody is repairing ballasts especially apollo because of the epoxy fill saying its impossible etc well i just wanted to stop by and say that im on my third apollo repair it can be done just a lil work is involded in cutting the epoxy away carefully i have been using a screwdriver mostly and a right angle peice of metal to help slide the board out most repairs are fda50n50 mosfets and the scs206 rectifier diodes i only wanted to post this to save people money dont be afraid to fix something just be careful you dont get shocked and dont forget the thermal paste ps i typed all this on a phone srry ahaha im open for questions

    Also i have repair ballast that have been fully submerged in water (basement floods)the epoxy helps then, just clean up all the corrosion with new solder

    Nice i have an OLD panthom digi balast that i used for years then

    One day it went on for about 15 min then cuts off.

    Try again goes on for a few then cuts off.

    Any ideas?

    Luckily i had a new light waiting .

    But it seems like a shame to toss it if i can fix it.

    Let me know

    Well id start with anything that has a heat sink those r always the first to check your wanting to check for signs of burning and or the component shorting use your multimeter and remember its always gotta b removed from board to test any questions on how to troubleshoot different components youtube is your best friend p.s. always look for blown/leaking capaitors if the ballast has a few years on it
    Your symptoms sound like a cap but u never know till you look

    If you're competent enough to order the correct parts from digikey chances are you can repair just about anything. Better question is for a $75 ballast is it worth your time? If you happen to have the caps or mosfets laying around maybe. if you gotta order stuff and wait around or spend 6 hours cutting away Silastic I would argue just toss it. I find these days 6 hours is harder to come by that the cash to replace.
