Apollo electronic ballast repair

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.
