Well, my VSX 49txi is some what dead. I get no sound from any input, analog or digital. I have tried direct mode and all surround modes to no avail. If I bypass the preamp by taking the jumpers out and run an external preamp into the front amplifier inputs I get sound, so the amplifier is working. The preamp senses signals (when I hook up digital and analog sources and set the receiver to auto it selects correctly), but there seems to be a communication failure between the preamp and amplifier sections. Now it gets better......when I hook up to the Multichannel inputs and select Multichannel Direct mode all is well. If I select Multichannel Adjust it is back to nothing. Multichannel Direct 2ch is just like Stereo Direct 2ch mode in sound so that is fine, but I only get one input and that is no bueno! Any one have any idea's????

I also was considering some type of conversion. If I could make this into just an amplifier that would be pretty good, but man I really like it as a surround receiver...........

Did you ever figure out what the problem was?

Sooo,

I did figure out what the problem was/is. These receivers get pretty hot and if not properly ventilated can cause damage to themselves. The DSP board can become desoldered and the chip may suffer damage in the process. I found another 49tx at a thrift shop and picked it up for cheap, only to find that it was experiencing the same issues (exactly) as the one I already had. I sent my receiver to EBC Electronics and Paul was able to fix the DSP board for a very fair price (in my opinion). I then sent in the other 49tx and had the same exact problem fixed. So, If any one has a Pioneer Elite VSX 49txi or 49tx that has no output this is very likely the problem and can fixed for much less than a used one with no remote can be had for. If you want to be sure it has the same problem just hook up a source, select B speakers only, select direct mode and see if you get audio. If you do get audio this way but no other way, the fix above should be good for you as well.

CHEERS!

Just chiming in 2 years after goodtimes quote. These 49 TXi's are turning up in every goodwill in the US. All due to the same problem, NO SOUND.
I took Goodtimes advice and am going to send it to Paul at EBC Electronics in NJ to have him look at it. If you go on there webiste, they say the usual No sound and DSP board rebuild runs around 240$ plus the cost to ship it to and fro. If you dont care about new technology (I.E HDMI) like me, then send it in to get repaired.

I Had little problems with my 49 TXi and I just did a master reset (Press Dolby NR and Power at the same time) and bam, unit quit outputting sound altogether. It used to be intermittent, (and would still work in DIRECT mode) but now its nothing. I knew the day would come when I had to send it in for service. But the good thing is if you were to just "replace the board" the same problem would happen again, vs. EBC electronics actually rebuilds and upgrades the faulty parts. Pioneer Home electronics went under in 2014 so you cant get the boards anyways.

Ill post an update after I get the rebuilt unit back and let you all know about what was wrong and the outcomes with EBC.
