Hi Guys,

All the Xenon Guys are aware of this infamous issue that could end up being expensive to fix. Cheaper way around is to try the bulb replacement first but sometimes, the ballast is the root cause.
I decided to start a little investigation of what could be the problem and I finally was able to separate the board from the housing.

Well I am glad to tell you that I found the problem!!!!!
This ballast was totally shot: once powered, bulb was coming ON for a millisecond and that's it.
Replaced Transformer, capacitors, regulator and voila!!!
It seems that the components are made in Germany (same components used in the aircraft I am working on) and Mouser or other, don't carry them
A total of 4 components need to be replaced: 2 are faulty and 2 are weaken due to the faulty one

2 capacitors
1 transformer
1 Regulator

As previously said, I got these from my Company stock and we have specific parts numbers. I will need to go back to Engineering blue print to see if I can get a cross reference.
I hope by adding this, the post won't be locked, but for info, the total part cost for 1 ballast is $59, way better than a new unit !!!!

Well, if you have a flickering issue, the Community has now a solution!!

Hi Phil great writeup,
couple of questions, how big is the Cap how many micro-F? How large was the regulator? and the transformer? Could you indicate on the photo what needed to be replaced for the new comers? Maybe do a little DIY? Thanks for your comments

Unfortunately, I do not have these details and can't check them either on the new part because, as previously said, I need to get the blue prints first (details are not written on the Aero parts).
In the meantime, if you have the problem, I would be glad to repair them for you
