Dropped my Digital Ballast - Now my T5's wont turn on?

[Liquitech]

I dropped my digital ballast today while moving it and now my T5's wont turn on. It's a Giesseman fixture and the metal halides still work but not my T5's. I was wondering if its the digital ballast that needs to be replaced or is it the t5 ballast that happen to go?

Can you open the casing? It may be a wire was knocked loose or something simple to fix like that (hopefully).

Thanks ill give it a look. I was kind of thinking the same thing myself.

Well it looks like everything is fine inside the ballast. Since I have to get a new ballast does that mean I have to install new ballasts for the t5's within the fixture?

I thought it was a digital ballast for the t5, did you mean controller?
If it was the digital ballast then I would think it is the only ballast you replace, any pics of it?
How old is the fixture?

Well the giesseman has a built in t5 ballast in the metal halide ballast.

So today I went to J&L and bought some new ballasts for my T5's. I then got home and took apart my fixture. Now there was quite a surprise underneath the hood. My metal halides were wired in a series rather than on running on seperate ballasts. There was T5 ballasts already in the fixture that someone installed which was also hooked up to a 250 watt ballast. Very odd! I just ran a plug to the T5 ballast and it turns out the T5 ballasts work! Also I don't think my metal halides were running at a full 250 watts each. You never know what your buying when your buying used sometimes!

Lol no way a 250w ballast can run t5, they would pop. What he probably did was run the hot spliced off supply on the 250 line. But anyways running dedicated lines to each leaves you with the option of having the t5 come on before halide and vice versa...

lol i know that. giesseman ballasts come with t5 ballasts built in to them so i was trying to say they were running off of the built in ballast and not the ones inside the fixture. i am by no means an electrician so there might be some things that i say that don't sound right because its hard to explain something when you know not a whole lot about. i wasnt trying to say the t5's were running off of a 250 watt power load. sorry i should have went into more detail.
