Help--400 watt hps ballast wont turn on

i have a hypotek 400w hps- mh dimable ballast. 1 grow under it. i bought a new bulb and nothing.check braker and all that still no power to my ballast

any help please

OK don't post multiple threads asking the same question.

anyone have a answer

Fuse?

If you plugged it in and unplugged it and then tried to plug it right back in then it won't come right back on,other wise i say fuse as coho says.
Does the fan if available still come on?

Try the Ignitor (inside the case). It is a small can in (usually) an oval shape about the size of a Zippo lighter. If that's "OK" then the Capacitor (round like a red bull can) could be dead. Either one being bad, it won't ignite. I suspect the Ignitor as these usually go first and they take the brunt (surge) of the start-up electrical load.. Even the best Ballasts need theese parts replaced about every 2-3 years depending on usage and their quality. Some electrical parts simply go for no reason. They are all made as cheap as possible.

if u have a volt metter check to see if u r getting volts to it if u r then look at the bulb u mit not have it in right hope this works out for u

Its brand new...I opened it up and there was some kind of spray over top of everything
