I have a couple of older Y115P powered speakers that make quite a severe hiss.  Even with no input and the volume turned down as far as it goes, I can hear the hiss from ~30 feet away.  Yorkville's technical support tells me this is abnormal, although if that is true, then both speakers have failed in the exact same fashion.

Is this something that could be DIY fixed, or should it be taken to a pro?  If the latter, does anyone want to hazard a guess as to how much it would cost?

Other than the hiss, the speakers do not sound amazing, but produce adequate sound.

Thanks in advance to anyone who has any suggestions.

My car wont do more than 80 miles an hour. Can you fix it?
Seriously, you can only tell by proper measurement if you have a problem.
And a cure over the internet is not possible.

Sure, how much cash do you have for me to spend ?

Excessive hiss on older equipment often is the result of failing capacitors.  Sometimes you can visibly see failing capacitors because they look leakey or bulged.  Replacing all of the caps on the amp board would only cost a few dollars and some time to solder them in place.

Are you running it thru your snake? 

Sorry, I couldn't resist!

Thanks!  I'll go take a look.

I'm afraid none of the capacitors are bulging or leaking.

Unless there's anything else I should check first, I think I'll just replace the capacitors and hope for the best.

Today I noticed the hiss persists for about three seconds after disconnecting the power, in case that's relevant.

[Chrysander 'C.R.' Young]

Three seconds is probably about how long it takes for the last of the stored energy in the power supply to dissipate.

Those are some older and less than spectacular speakers.  If they cannot be fixed easily, there is a fire sale going on nearly everywhere for the JBL PRX712M.  This would be a profound upgrade.  I bought two myself and they sound quite good.
