Mine still works. Well, everything but the iffy HDMI. Some days I can get through a full movie, other days I have to reset power it off/on a couple times during the course of the movie. I finally "gave up" and just ran all the HDMI stuff directly to the TV, then from the TV back to the 254 via optical. Works fine, and I can't tell a difference (oops... did I just out myself as being a low-maintenance home theater person?). And even if there is a slight difference, not having HDMI drop out at during peak scenes makes up for it.

FWIW, mine was a late-cycle refurb from HK. It had most of the updates done at the factory. I'm running the last firmware. And I've had small computer fan sucking air over it (drawing from the bottom of my cabinet) since the beginning -- I don't think it's a heat issue. And at this point, I don't even care. As long has the optical in and zone 2 out keep working I'll keep running it!

Well I can't FRACKING believe what just happened!!!! So I was listening to my newly purchased A Perfect Circle, Mere De Noms 180gram Limited Edition album and my AVR 254 went into Dolby H:BYPASS Mode and will not play any Audio? The Auto Setup plug is not plugged in. I unplugged it from the power outlet for 20 minutes then plugged it back in same thing? I plugged in the Auto setup adapter (into the headphone jack) and went through the speaker setup, it sent signals everything seemed like it was going good then it finished and I unplugged it and it went back into DOLBY H:BYPASS mode? Anybody have any idea's what could have happened or any help? Please!!!!!!............I am totally crushed and kinda upset!!!! I tried it on all modes (xbox one/FM/TV/Aux record player) get the same message. Any input would be appreciated.


Kindest Regards,
Eddie

If your using HDMI for audio, try switching to optical and see if you get sound

That is how i'm using it (optical for all audio) besides my pre-amp for my Turntable going into the Aux of the HK but after letting it sit I tried it again (very late last night) and all is well again. I'm wondering if it was over heating? Yesterday and last night was pretty worm here in the East (Boston area) so i'm wondering if that had something to do with it. I did have it cranking ( Wife and I rocking out with some cocktails) I have it in a enclosed cabinet and thinking I might need to add a exhaust fan in there? There's about 7 inches of clearance on top and about 5 inches on the sides but the front is open. Has me worried though. what do you think?

It sure won't hurt it. For $10-20 you could take the heat out of the equation.

Don't want to lose my HK 254, What a strange coincidence though I get this thread going again asking if I was the last one with a working one with no problems!!!??? and Bam that happens.

Ended up getting this one for the top part of the cabinet for the Harman Kardon 254 http://www.amazon.com/CabCool-Lite-C...ilpage_o01_s00


Cut a hole in the side of the cabinet to accommodate the exhaust fan and got the front open and all is well as of now.


And the single fan for the bottom part of the cabinet for my Xbox One and Turntable. Listening to Physical Graffiti LP and felt the top of the 254 and big difference in heat. I don't know why I didn't do this years ago???!!!! I thought you was supposed to get smarter with age???? Not in my case apparently.


Take care everybody!

I said the same thing after I went through 3 avr's, and it had the recommended ventialation each time. My flagship 3700 ran hot even when no power was being sent to speakers, idle but on. Oh well, live and learn.

Ok just an update, since I added the exhaust fans everything has been good. It has not done "that thing" again since (Thank goodness) so I've added the Cambridge Audio Azur 551P pre amp and purchased a Shure 97XE Cartridge. Picked up a Technics Needle Gauge Adjustment and used the protractor for the Audio Techinica lp120 and HOLY CRAP!!! I'm totally amazed at the sound coming out of my system!!! I'm in love with music again (well 60's and 70's music LOL)




Take care to all my HK friends and everyone.
