I got a serious problem guys. My Pioneer Elite VSX-49TX would run fine for about an hour or so and then it would cut it self off. When I checked the receiver it was boiling hot. Any Suggestion. My Receiver has less then 10 hours on it. I bought it Brand new and never used it. I just setup my Theater and started using the system and now this problem came up. Any suggestion

I've been using this same receiver for the past 5 years in my home theater with no problems. Before sending the unit in for service, I would suggest the following: First check that you have good ventilation in the rack where the receiver in mounted. Poor ventilation is the most likely cause of the problem you are seeing.

Next, disconnect all wiring from the back, turn the unit on, and set the volume to zero. Without any load, does the unit still get hot and turn off? Next, connect a CD player and 1 pair of known good speakers or a good set of headphones. Repeat test, but play a CD at low volume thru the speakers or headphones. If it passes this test, then you may have some wiring issues that are presenting an extreme low-impedance load to the receiver. You may also have a bad speaker, or some suspect connectors.

Keep in mind that the receiver needs to run in a well-ventilated area. I've mounted 2 small dc-powered fans on the back of my receiver using small velcro strips to mount the fans on the top rear panel of the receiver. While this sounds like a hack - the fans are virtually silent, and cannot be seen unless you are looking for them. They blow air across the receiver, when it is turned on. This helps prevent warm air from accumulating in the equipment rack.

If you can't pass the above tests, and you have plenty of good ventilation, then it's likely something in the receiver itself. It's good to check out the possible causes before sending the unit in for service - because if it is not the unit itself - then you would be wasting time and money for a repair you don't need.

Thanks for the help Mike... Your idea worked perfect it was bad wiring. The receiver is working perfect with out any problems. Although I do feel that even with the ventilation the receiver seems to be running a bit hot. Is that normal or should I install some fans. If yes then could you please point me in the right direction as to where to buy the fans and what kind.

Thanks once again

from computers, to Xbox's, to a/v receivers.....electronics just run better and longer if they are kept cool. Heat is your enemy and a couple of small low noise fans will help greatly.

I own a 49txi receiver and it does run fairly hot. This is completely normal. What I did was buy a Proceed three channel amp for the front soundstage and it still runs pretty warm compared to other receivers I've owned in the past. Giving it good ventilation is important but I think it will run fairly hot all the time.

You have a great receiver so sit back and with your wiring problems behind you, enjoy it.

I also own the Pioneer 49txi with a 2 channel Halo amp for the fronts and the Pioneer still runs fairly warm to the hand. I once owned a Rotel 1067 for under 30 days that I returned for the sole reason of exteme heat, my hand could not stay on the top of that unit for longer than one second and thats no exaggeration. So in comparison the temperature of the 49txi is a non issue.

I am also a Pioneer VSX-49TXi owner and can confirm that it does indeed run hot even if you are not playing anything and have it on idle'ing. This is normal. I think they run their amplifiers biased class A so that it will always run hot even with no signal playing.

I have had it since new when it first came out and have never had a problem with it. Still running strong, even though I recently bought a new Onkyo NR-905 AVR (for its HDMI 1.3 capabilities) I think the Pioneer 49TXi sounds great and a wee bit better than the Onkyo sound. But the Onkyo is great sounding too. Just a touch mellower.

I absolutely love the 49TXi and wish it had HDMI 1.3 capabilites... alas, it does not.

Thanks a bunch guys.... I appreciate all the advise. I was actualy thinking about selling the 49tx and upgrading to HDMI Compatible receiver but now I will stick to this one. I hardly have about no more then 15 hours on the receiver.

P.S. I only use it for my blu-ray nights. Should I just keep using the optical cable for the sounds and HDMI for video or should I upgrade to HDMI receiver. Does that make a big difference or is it all the same.

Thanks

Ron

You can use the optical in for Dolby Digital and DTS but if your Blue Ray player has 7.1 analog outs you can use those to get all the sound formats that your player can decode. Plus our 49txi is one of the few receivers that allow full mass mgmt and time alignment of these analog inputs. You can still use the receiver for a good long time. Now if your blue ray player doesn't have 7.1 analog outs, then you must use optical for surround sound.

I have a 49TXi and love it. Yes it does get hot, but with adequeate ventilation 9+ inches of clearance above it's not all that bad.

I have it in my family room theater. When blu-ray moves in I will keep it with 7.1 or 5.1 analog imputs.

The sound is amazing and warm (yet still towards the neutral end). In my dedicated theater I have an Integra DTC 8.8 for all the HDMI switching and decoding goodies but the Pioneer still sounds a bit more full. Perhaps that's the MAACC vs the Audessy Multi EQ XT but they both sound great.

Buy a blu ray player with the full 5.1 or 7.1 analog out and full decoding in the player and don't look back.

All of my sources in the theater (except for an old LD player) are 1080p24 and the receiver merely passes them through. Save the money on the Upscalling and HDMI switching if you don't need it and spend it on a fantastic high end Blu (or if your a betting man - HD-DVD) player and hook it directly to your monitor (buy one with 3 HDMI). Iif you have new HDMI equipment and only need one HD format player (vs CD/DVD/SACD/DVD-A/Blu and HD) then the 49Tx-i is still the ticket.

I have used 4 hockey pucks under the 49tx feet for several years, and have placed the unit on top of my rack, not inside (also like to look at the 49TX also). The extra inch of air under the unit seems to keep things a little cooler.

Only time the receiver shut off was after a calibration in which the individual levels were set +8, + 9 etc. by mistake and a heavy night of playing way too loud of music mixed with way too many drinks.

I have no upgrade plans for this unit, sounds great ( looks great).
