Help! XDA-2 blew a fuse tonight

[pebecker]

I keep my stuff unplugged from the wall outlets when not in use for a few days - so tonight I plugged everything in and grabbed my XDA-2 remote and hit the power switch.  It made the relay click sound it usually does, the screen lit up for maybe half a second, then it went dark.  I cycled power and even changed out the remote batteries trying to get it to come back on.

After a bit, I unplugged everything, pulled it from the stack and opened it up.  On the power supply board there's a single fuse that my VOM says is open.

Is this just a fluke thing or does anyone think there is more going on here?  I have a full lab & equipment at my disposal if need be, but I'd rather just replace the fuse and have it just work.  The thing has been running flawlessly for quite a while and I'd hate to lose it.

Any ideas here?

Thanks,
Paul

Don't make a blown fuse more then it is. Replace the fuse and listen to your tunes.


Thats step one! Hopefully there won't be a step two. Good luck.

Just noticed that was your first post! Welcome, so glad you're here! So many nice people to meet. I'll get you a tall glass of 

EmoBlue!

I agree with nick,why worry before you have a real reason to? Replace the fuse and if everything is fine forget about it and enjoy.If the problem repeats then you can begin to look for the cause.Good luck and welcome.

I ordered and finally received the proper fuse and it works just fine. Thanks!

Sorry to revive an old thread.
I may have the same issue,

what/were are the fuses located? and where do I get the said fuses from?

I have an XDA-2 also and it is not powering on.

Open it up and take a look. From Googled pics it appears to be on the circuit board nearest the power cord.

You may be able to get them locally at Home Depot or Lowes, but I would probably just order a few from Mouser once you have identified them.

Edit: You can also give Emotiva a call and ask them directly which fuse is in the unit. It's not always discernable by reading the writing on the fuse.

Thank you cawgijoe

I wanted to give eMotiva a call before I openned it up, I tried 1-877-366-8324
but I couldn't get past the automated voice message and left me always to leave a message after the beep.

Is there a technical support line?

The issue is; my emotiva XDA-2 is not turning on, i tried various power cabels, the power cable is not the issue (i.e. from a monitor and PC)
The outlet is not the issue (as I type this computer is plugged into the outlet I was trying it with)

Hence this thread was my only lead to something similar which I assume.

You have to keep calling till you get someone. I find it doesn't usually take long.

If it's not powering up, it could be more than just the fuse.

sounds like good customer service to me. 😉

Thank you! 
Yup they called me back on the same day! Great turn around time from leaving a message. 
They said the same thing; either your fuse is gone or there is something greater with your power supply unit! 

I asked if I can open it up, which I did today. 
Therefore, I opened it and took the following pictures: 
incase the images hosted here don't work, also hosted on imgur > IMAGES OF XDA2 DAC Power Unit/Fuse Hosted on IMGUR



They said to see if your fuse is burned; I can't tell, (I am not very experienced).

I also assume "F03" is the fuse? 

Also, I didn't know how to open the latch to remove the fuse to further inspect and use a multimeter to check its functionality.

To remove the fuse, just pry on one end. It just snaps in. From the pics, the fuse looks intact.
The first and cheapest thing to do is buy a new fuse, replace it and see if that solves the problem.
If not, I would call Emotiva back and ask if they can repair it.

[audiobill]

Very gently, with the unit unplugged, nudge the fuse up with a small flat blade screwdriver. Then, with your multimeter on ohms (omega symbol), touch the ends of the fuse.with your meter leads. If the meter reads 0, your fuse is good and you have other problems. If it doesn’t read anything or a very high number the fuse is blown and you may have other problems.

[concernedcanuck]

Thank you AudioBill and cawgijoe!
I will get to the multimeter but wanted to ask

can I get help to identify what fuse this? at F03?

I assume it is a: t500mal250v fuse 
 
To purchase a new one.

What does it say on the fuse? Also, measure the length of the fuse.
Armed with that information you should be able to order.

If still unsure, call Emotiva and ask them.

I'm curious about some things.
The sticker shows "T500mAL 250V", but the fuse looks like it starts to say "50T . . . .", then can't read the rest. So I'd be wondering what the rest of it says. While it's not uncommon to use a different spec part from what is printed on the circuit board, the fact that it's a sticker instead of being printed on the circuit board would make me think the part is not correct "if" the fuse is a different value from what the sticker says. The point being that the sticker may have been added as a correction to what might be printed underneath. So I'd be wanting to call Emotiva for clarification if the part doesn't match the sticker.

The fuse clip closest to the sticker seems to be corroded, at least that's what it "looks" like from the photo. If so, I'd be more likely to want to test between the fuse clips first with the fuse in place: general continuity and then Ohms. Then test just the fuse, even if the first tests are ok.

Not looking good, I’m afraid.
The condition of that fuse holder is the indicator that somethings up with that unit, unfortunately. Those fuses are there to stop catastrophic failure and to leave a component serviceable.

[cawgijoe]

Looking closer at the picture....regardless of the corrosion on one end, the fuse appears to be too short.

I would remove the fuse and clean the corrosion off. Test also as suggested. Then call Emotiva tomorrow. Ask them what fuse goes in there and what to order. They may send you a couple fuses.

[concernedcanuck]

Thank you cawgijoe, ttocs and 405x5!

This arms me with enough knowledge. I will test you guys have suggested (time to get a multimeter!)

I never used a multimeter (sorry guys, just a 20 year making his way through the real world)

I'd be more likely to want to test between the fuse clips first with the fuse in place: general continuity and then Ohms. Then test just the fuse, even if the first tests are ok." 

To do this above test ^, 
connect the ends of the multimeter to each end of the fuse clips with the fuse in place, turn the dial to "omega" for Ohms
and than let the multimeter do its thing? 

but what do I turn to for continuity in the multimeter?  


will then remove fuse, clean the holder (any specific way to clean it, damp cloth?), 
test the fuse.

Obviously, unplug the XDA-2 first!

Some meters have an audible continuity test, some don't. But the Ohms resistance will do, if there's a reading of 0Ω as audiobill says, then there's continuity. 

[cawgijoe]

Go to the hardware store and buy a can of electrical contact cleaner. A company called CRC makes some.

You can also try rubbing alcohol....at least 70% or higher alcohol content. Put the alcohol on a paper towel or preferably a cloth and use that to clean the holder.
