i have a behringer bx4500h and doesnt not turn on, i replaced the fuses and nothing, any idea what it can be?

You made sure you've plugged it in, right?

In all seriousness, because I know this thread will get ugly fast, Behringer isn't known for their quality control. That's not to say they don't make good products, but reliability is hit and miss.

Has it worked previously and stopped working? If it's new and still under warranty, send it back and get a new one. If you REALLY need to fix it yourself, pop it open and see if maybe a wire has come loose somewhere.

lol no it was actually a trade for a busted cab i had so it was free, but everything seems to be connected correctly, the guy i got it from said that it just didn't turn on. i replaced the fuses and still nothing

I'm not a technician, but twenty to one says it's fried.

trueno87 · #5 03-28-2011, 03:43 PM

would there be some type of odor of a burnt smell or something, i mean all looks good

Jonathan1990 · #6 03-28-2011, 03:45 PM

Yes, it should smell like KFC

I assume you've tried using different power cables already? Are you sure the fuse holder is connected properly?

Good idea to change out the power cables (they're standard, easy to find) and to make sure you've changed all fuses. If that doesn't do it, the next step is to take it to a tech for service. Nothing more you can do as a user.

I really like the BX4500H...it's a great sounding amp. I used one as my primary amp for two years and it performed well and never missed a beat. I think it's one of the best units that Behringer makes. Unfortunately, anything can be abused or fail.

Regardless of whether the amp in question is a Behringer, SWR or Ampeg, trading for a dead unit is ALWAYS a crapshoot. You're taking a chance when you do it.

lol to Jonathan i would prefer popeyes but that's another forum lol, and wshines yea everything is connected properly

Jonathan1990 · #10 03-28-2011, 03:59 PM

Yeah, of course I hope it'll work again, but I have had unsatisfying experiences with this model. Bring it to a good tech (most music stores have them), some of them don't even charge for the autopsy.

Pilgrim · #11 03-28-2011, 03:59 PM

You may not smell anything burned. It could simply be a component failure, not a melt-down. I'd put an absolute TOP price I was willing to pay for a tech assessment of about $75. After that, you'd be better to find one on the used market.

this is really bad advice and more likely to do more harm than good. All techs will give you examples of someone doing this and it being a real problem to fix after that experience.

OP take the thing to a tech and get it looked at. The guy's bill will be much less than your life is worth.

It's not like I told him to pull some crap out. If you remove it from the casing, you can visually inspect if a wire has popped off somewhere. I don't see how vision requires technical expertise, or is even open to him screwing something up.

trueno87 · #14 03-29-2011, 10:34 AM

lol thanks i'll probaly just take to a tech hopefully he can figure it out.

Because someone needs to KNOW what they are looking at in order to identify what could be a problem and what is quite normal. While the amp is open you are exposed to mains voltages. The caps in a SS amp can store enough current to provide a bad burn.

My buddy, Billy (757nightmare), had a similar situation with his identical Behringer head. It acted as if the fuses were blown but that was not he case. Turns out the entire switch was bad. I had it replaced by a tech here in Virginia Beach.
