JVC RX-9010VBK receiver - premap section won't turn on normally
A friend gave me a JVC RX-9010VBK DTS/5.1 surround-sound receiver
that's a few years old. I carefully read the manual, and it seems to
have an odd problem that is getting worse. When I turn it on from cold,
either by remote or front panel, I hear a couple of relays click and it
powers up, but there is no sound from any of the source inputs. When I
first got it, I would just turn it off and on again once, and it would play.
Now, however, I have to repeat this 5 or 6 more times to get it to play. When I
use it for a little while after it turns on okay, and I then turn it off and
on again, it powers up fine. However, if I wait a half hour, the
problem returns. I can hear residual hiss when I turn the
volume way up, and a slight thump when I switch between sources. I also tried using headphones with the speaker outputs
off, but no still no sound. So, it
seems that the preamplifier stage is not powering on, but the power amps
are okay ("protection" does not come on). And, the display shows
"tuned/stereo" with the tuner and goes on and off normally when I switch
stations. I'm somewhat handy with fixing basic electronics, so I really could use an opinion
as to where to start looking in the circuitry (bad capacitor/regulator
It sound like a bad connection. The first thing that I would do is tighten all the ground screws that hold the circiut boards and the heat sink to the chassis. If that doen't fix it, flex the circuit boards slighty to see if the relays chick on and off (disconnect the speakers first). It could be on the input board, on the relays themselves or just about anywhere.

Make sure the speaker is good by connecting it to a known good working site. If speaker is good, make sure it is properly connected to center speaker terminals. Then if it is a surround receiver make sure that the sound mode is one where the middle channel works such as 5.1 DTS, etc. If the center channel still does not work then the problem lies with the decoder chip that is not working properly and sending the center channel info to that specific amplifier.
The problem can be the cable or speakers or RX-V463 or settings. Need to check one by one.
Set the RX-V on DTS or Dolby Digital
1) Check Cables - connect the 2 (surround) cables from RXV's Centre Out to Centre speaker. If the Centre speaker works, then cables are ok.
2) Check speakers - Connect each Surround speaker to RXV's Centre out. If it works Speakers are ok.
3) Check RXV - Set it on DTS or Dolby Digital
Connect RXV's surround out (one at a time) L and R to the Centre speaker. If there is no sound, the problem could be RXV's settings (I need to read the manual).
I'd suspect one of the controls that would be overriden by analog direct is unknowingly activated. LOOK at the front panel and interpret every indicator for how it could cause silence. Refer to the manual for those you don't understand.
Any Tape Monitor activation would disable digital sources completely.
See page 14 for how Line Direct affects DSP modes.
Hi, This is a common problem. Each input will default to analog. Even though you have plugged an optical cable into the inputs of the Receiver, you have to change that input to digital. For example, if you connect a CD player RCA cables to the Receiver. The receiver will recognize the Analog signal at the CD input. If you unplug the Analog RCA Cables and plug in the Digital optical, the receiver will still be at it's normal default input for the CD player which is Analog. You then have to switch the input, using either the remote or it may be able to be done with the buttons on the front. As soon as it is changed to Digital, you will get nice sound. Hope this helps, Happy New Year, Mark
The optical cable will get you 5.1 surround sound - but only if the game has surround sound and your PS3 is set to output surround sound. Even the PS2 will do that. DTS is one 5.1 surround format and the optical cable will handle that too.
Check your settings on the PS3 and make sure you are: Using the optical out, and outputting a 5.1 surround signal.
I think you will find your JVC is adequate for this purpose. Please post back if you are unsure of how to set those options.
I dont know your reciver but if it has a hdmi input plug ps3 into it and set audio on ps3 to pcm,this will give you digital surround eg multichannel,if not you must use a optical cable from ps3 to reciver and set ps3 audio to digital.
hope this helps.
Best thing to do is to put the unit in 5 channel or 7 channel mode. That will send left ch information to the front left and rear left speakers ( both will get the same information). Ditto with the right channel. The center channel will get centre channel information.
If all the speakers work, go out and rent TOP GUN. ( yes its old), BUT there are a few extreme scenes , one of which is the elevator scene, where the camera changes perspective and suddenly you hear the elevator doors close BEHIND you through only the surround speakers ( have the unit in surround mode....NOT 5 or 7 ch mode ). If this works ok, then you have no problems.
Remember, surround sound only produces information in the rear channels when the information is there. To check out the digital and DTS decoders, get an action flick. If you can, get a remote too, because that will unlock many features about the receiver that you cant get to with the front panel controls. Also go to yamaha and download the owners manual ( its free !!).....that should get you going.....
