I just had my 'out of warranty' XPA-5 go into protect mode on channel two. That channel has never been used and it just started out of the blue. I disconnected everything and with just the power plug it still cycles then trips on channel two. I suspected the board was fried but everything looks perfectly normal inside. I haven't tried the hair dryer trick but doubt it would help - all fuses look fine as well. Any ideas or am I s.o.l.? Anyone have a XPA-5 they want to sell on the cheap so I can swap boards?
Try blowing all the dust out of it. It's a long shot, but maybe some dust accumulated on the contacts and is causing a short. How long out of warranty is it? If it just went out, Emo might just repair it anyways. A lot of company's will do this. It shows that they stand behind their products and makes you the customer more likely to buy something else in the future.

There isn't really any dust in there - since I keep my stuff pretty darn clean on a regular basis.
I wish I could find one used for $500 at this point so I could have some spare parts lying around.
It's $100 each way for shipping(more than likely less on the way back though), and I'd have to pay $300 to get it tested and fixed. They will not supply any parts or boards, they will only take it in for repair, that's the only option in the USA. I bought it in march of 2008, and bought a XPA-5 and XPA-2 back then when they were just starting out - no love for being an early adopter, thats for sure.
I might as well just hope for a black friday sale on a Gen2 at this point since my local A/V repair guy isn't exactly cheap either.
My wife and kids came home and were like "what are you doing?" as I'm taking a hair dryer to the amp on my kitchen table. After a minute or so I clicked the power button and magically it didn't fault and go into protect mode. I hooked it back up to everything, turned it on, no fault. I just finished watching 2 hours of TV without issue...frickin hilarious.
Spend $500 to have it fixed - or - spend 1 minute with the hairdryer blowing in the vents.
Kudos to whomever discovered this trick so many years!!!

still sounds like a dry joint or maybe just a bad cable join...I've never been able to fault Emotiva service, but 5 years is a pretty good run for any warranty...most will give you only 1 year and at best maybe 2/3... more than that in the hifi industry is rare...especially for an ID company.
Ive had 4 xpa-5's .. 2 gen 1's and moved them on but recently got 2 of the Gen 2's as my needs changed and very happy with them. Ive still got 5 of the UPA-1's that have the same modules and no issues there either. Ive seen a couple of XPA3/5's that had totally plated the output stages but that was probably due to either a short in the cabling or a cooked speaker.
They are fussy about non grounded inputs with signals and many a bad cable or connection will sent them into the red protect.
My second XMC-1 is here...I LOVE THEM TWINS !!!
I have a pile of stuff that pushes out squiggly waveforms from smaller squiggly waveforms that sometimes come from 1's and 0's.
It's wonderful to behold as long as you don't let the magic smoke out.
For the most part it just all works...when it doesn't then it's time to rub a few brain cells together and soon enough it's all good to go again.
FWIW I doubt the hair dryer reflowed bad solder joints in this case. With no warranty and not much else to lose if the amp goes into protect mode again a good exam of the PCB boards might be a good idea. And a simple touch of a good soldering iron should quickly fix any bad joints found.
As for the cost of repairs - why doesn't Emotiva offer replacement parts for their amps? They obviously have those parts in stock or they wouldn't have given a repair estimate.
