Question about Pioneer VSX-816-K/S Receiver

Sound cuts out.

Hi, I purchased a new Pioneer VSX-816-K from amazon about 4 months ago. Has been working great. I have a Directv TIVO connected to it ( about 1.5 yrs old ) via S-video and Fiber Optic for Audio. This setup has worked well for the last 3-4 months now. However, specifically in regards to the Fiber connection - my sound is now randomly cutting out for about a 1/4 of a sec. I took a can of air and cleaned the ends of the fiber - didnt help. I Also get the cut outs when i play dvd's that has been going on for longer than the tivo issue.. My dvd sound is connected via Coax. I didnt think much of the dvd issue as its a quite cheap $40 apex. Right now i removed the fiber and i have it plugged in via composite l/r plugs.. its only been this way for 4 hours or so.. and so far its been ok... I play the XM sat radio stations.. so i should be able to spot it quickly. ITs odd that its doing it on BOTH the coax and the fiber.. The unit isnt heating up... its hot.. but nothing above usual ( at least to me ). Should i try and swap the fiber?... I would find it quite suspect/odd if BOTH my fiber cable AND my coax cable are bad. Again.. its only these two inputs that seem to be causing this.. i can put it on FM radio.. and play it all day no issues.. no cut outs. It is still under warranty with pioneer.. but its prolly gonna cost me 45-50$ shipping costs just to get it to them. Possibly a componant that controls both the coax And the Fiber may be overheating? thanks for the help - jb

Re: Sound cuts out.

I had the same issue with the front right speaker randomly cutting out. Thought it was a loose solder joint however upon taking it apart i found that something near the back panel was shorting out. While apart i found that wiggling the rear panel would cut in and out the speaker. Also the fan would turn on when the speaker worked, which until i took it apart i didn't know it had a fan. I removed the back panel by taking out several screw the hold the cable plug-ins. once the panel was out i insulated it with electrical tape then used a utility knife to cut out all the cable connector holes. I also took out a couple screws on the main board so i could lift it a bit from the back and ran electrical tape over the solder point for the speaker connectors. Put it back together and haven't had any cut out's since. I now notice that the fan now runs all the time exept when i press mute. I also hear a single tap noise for a second when i mute or turn off the receiver. I can certainly put up with that though. Hope this helps someone else, I put up with the speakers cutting out for 6 months before i got around to taking it apart. Also those bannana plugs are a rip off, I went to future shop to buy them and couldn't beleive they were 25.00 for two pair. That would mean it would cost me 75.00 to do my 5 speakers. Thats more than i paid for my dvd player. anyhow i didn't buy them and just used bullet connectors, pack of 10 for less than 5.00, not made of gold but they work fine.

Re: Sound cuts out.

My vsx 816 does the same thing months at a time its fine then the cutting out starts seems to be on front channels make sure you have 8 ohm speakers and not 4 that was one thing i had over looked rushing to connect everything.

Re: Sound cuts out.

All the digital (coax and optical) is routed to the DSP in the reciever. The analog is converted to digial (internal to the receiver) and also goes to the same DSP. One possible difference is there may be a intermittent connection internally (cold solder joint, connector pulling apart) from the digital I/O board to the DSP section. Your analog sources are working (tuner, analog audio inputs) so the DSP and on.. are probably ok.

Vsx-816-k left channel cuts in and out.

You likely have a cold solder connection on the circuit board. Inspect the board for loose connections for the left channel - use a non-conductive pointed object and poke the board on several places while the unit is power-up. Be careful not to get electrocuted. Compare it to the right channel circuit - they are almost identical. If the unit recovers the left channel while poking, then you have found the bad connection. Re-apply solder to that junction - make sure you've dis-connected the power and dis-charged all caps before you touch and repair the circuit board.

Sound cuts out

No, this sounds like a speaker problem to me.
It sounds like the voice coils in your speaker(s) have been fried.
What happens is the part that is burnt does not funtion, but as you increase the volume/voltage the speaker "jumps" foward to a section of voice coil that is not as damaged.
Check your speakers!

This pioneer does not support HDMI, so for the best resolution you have to use video the component inputs and output, those are marked as Y (green), Pr (red) and Pb (Blue) and remember, this signals are only for video so you need to hook up the audio too.

Video issues w/ Pioneer VSX-816 AV Receiver

Receivers generally cannot or will not convert from one input type to a different output. That's not to say there may not be some high end models around that do that.

I have this receiver and have it setup as follows. Monitor out Component, S-Video, and the Composite video channel (since I have surround sound I have no interest in getting audio to the TV since I keep its speakers off anyways) to their different inputs on the TV. Warning on some TV's if you plug in S-Video you cannot then use composite on that same input channel as it will override and disable the composite. Then you only need to choose the appropriate input on the TV when you switch sources. In my case Tivo is S-Video, DVD is component, and most of my older video games and VCR are composite.

Having a TV that allows you to change the labels for the input channels is helpful with teaching others that may be less adept, or a snazzy remote that you can program to do everything at once.

There is no sound on my powered sub

Since you have a powered sub, the feed to it is a line level signal. If your unit is only 6 months old, it should still be under warranty. Check. If it is under warranty, have it repaired under warranty. Otherwise, update this and we'll dig deeper.
