Question about JVC RX-668V Receiver

1 Answer

Overload I have my receiver hooked up to a variable audio control on my tv so I have to turn the volume up quite high on the receiver (55-60) so I can get the loudness I want when I turn my tv volume up. I have run it this way for several years. Now when I run my receiver at this higher level for a period of time (about 20-30 minutes) while watching tv through the surround sound, the receiver shuts down and flashes "overload". If I turn the receiver off and back on it seems to work fine but will automatically turn the volume down for me. The troubleshooting in the manual says the speakers are being overloaded because of high volume or terminal short circuit. I have not had this problem in using it in this exact manner for over 4 years so I am suspect that the speakers could all of the sudden be overloaded. My concern is where do you think the problem lies, in the receiver or in the speakers.

Firstly check all your speaker wiring. Any damage can cause a short which will overload the system. You might not notice it, due to the fact that when you have the system on loud, vibrations move the wires on the cabinets or elsewhere. So make certain there are no loose wires near the speakers terminals into each one. If all that is good go to the next check.
Check If the amp is getting VERY hot when the overload occurs, then it might have a faulty part(s) on it. This might have occurred if you have been using speakers that never did match the amps requirements in the first place.

SOURCE: Overload

Try first to disconnect all of your speaker wires and turn back on this receiver. If the problem persists, you will need to take the unit into a shop and have the output circuits checked out, as these are all solid state parts that are soldered into the printed circuit boards and there are no user replaceable parts inside this receiver. Good Luck

SOURCE: my jvc rx-6010v is OVERLOADING?

The very FIRST thing to check is to make certain ALL of your speakers have an IMPEDENCE of 8 OHMS. (JVC - and others - say SIX ohms, but 8 is the "standard" you should use.) Virtually all speakers of even modest quality will include this specification on a label on the back of the speaker. You CANNOT run more than (2) TWO speakers with 4 OHMs impedence on ANY amplifier (technical discussion too long!) [NOTE: The internal overload protection system you mention is designed to help prevent permanent damage. However, you cannot re-set these systems yourself. Your dealer or authorized JVC service center must do this. Note, though, that if you have attempted to "cheat" the system several times, damage CAN be done that requires servicing.] But, before you take the unit in for service, there is one more "test": check for shorted and/or mis-connected/disconnected speaker cables/wires. Visually inspect connections at the receiver and speakers first. You might find something obvious! If everything looks okay, then disconnect ALL of the speakers; and reconnect and test them one at a time (at relatively low volume.) For example, reconnect the left front speaker, test the system; THEN add the right front, test the system,and so on, ADDING one more speaker each time - FIRST MAKING SURE EACH OF THEM HAS AN IMPEDENCE OF AT LEAST 8 OHMS! IF there is a short (or bad speaker) this will help isolate it. Hopefully one of these "fixes" will work for you. GOOD LUCK!

SOURCE: overload

Also could be speaker wire. Make sure all of the speaker wire is hooked up correctly and none of the wires touch awywhere.

SOURCE: it says overload

All the speakers connected right?
ANy speaker fuses not accounted for?
If you moved , someone may have dropped it or bonked it enough to crack a printed circuit board. That would make things unpleasant.
It's fairly easy to fix a cracked PCB if you know what to look for.

Receiver Not Working Properly with MB-2 CD


I believe your supposition is correct although I think your CD player is unusual if it has variable (audio) output. Most players have only low level output.

Speakers way too loud


You don't say how the Samsung routes out to the receiver. I assume you're using its RCA audio L and R jacks. Inability to adequately lower volume usually means you're NOT using a Line Level input, but maybe a speaker feed.

Your TV may have a setting for variable audio out, but even if you use the fixed setting you should be able to lower the playback volume to something comfortable with the receiver's volume knob. It does go down to completely OFF, right?

The response to your question is in two parts. There should be a couple of RCA jacks on the rear or side of the set labeled "output". These need to be connected to the input of the wireless headset transmitter. The second thig is to determine where the volume is to be controlled. The output from the set can be either Fixed or Variable. This means that teh volume can be controlled by the volume up/down at the set or not. Fixed mode is for connecting to a receiver where the volume is controlled by the receiver and changing the volume at the set will have no effect. Using the variable output mode will allow you to control the level of audio entering the transmitter and thus the volume. This assumes that the headphones do not have a volume control on them.

Setting the output to be either Fixed or Variable is controlled by the audio menu of the set. Please note that in variable mode, any internal speakers would need to be disabled as well.

Hope this helps,
Dan

Can't get sound from TV alone. Am using an optical audio cord. It is hooked up through a digital cable box. Even before this we couldn't get sound from TV alone.


I assume that you mean your TV speakers are not operating OR you do not get audio from TV channel sources.
If you want your TV speakers to work, make sure that the TV speaker is enabled in the TV setup menu.
If your TV is connected to the receiver to get audio from it through external speakers powered by the receiver, then make sure you have a connection from the TV labeled as "variable audio out" into the receiver on a panel labeled as something to the like of "TV/SAT IN" or "TV/SAT AUDIO IN." Then, turn the volume all the way up on the TV, then operate it with the master volume on the receiver.

We have the stereo hooked up to the dynex 42'' tv, as we did our other tv, we can not mute the complete sound and also sometimes we cant turn the volume up and down whats going on?


Since you have it hooked up to the stereo system, you need to go to on screen audio set up and turn off the TV built-in speakers (you will be listening the TV sound through your stereo system speakers), then go to the audio output set up and set it to 'variable' so the audio output of the TV's RCA audio out put will vary with the volume control of the TV (not all TV will alow this function), you will need to set the stereo volume to certain level (around 9~10 O'clock setting) since the sound coming from the TV will be controlled by the TV remote volume control. You can otherwise set the TV output to be at 'fixed' level, which means the sound output of the TV will not be controlled by the TV remote volume control, you will use the stereo remote volume control to adjust the sound level instead. I hope this is clear to you.

Hooking up Kenwood AR-304 to LG TV


You need to connect the TV "Monitor Output" which will be standard audio (RCA) red and white. Then you need to make sure you go into the TV's main menu and go thru "Audio". You may need to turn off the TV's internal speakers to get output via the RCA monitor out. If by chance it has a setting for "Fixed or Variable" for the output, select "Fixed" and control the volume thru the receivers volume control. If you still need further help, don't hesistate to ask! I can walk you thru it. Hope this helps

Low sound at high volume


Hi,

THe problem is with the variable resistor present behind your volume control knob, try replacing the volume controls variable resistor, this must work fine... this is a common prblem for all the music equipment that has knob control for the volume....

This resistor can be replaced with your product warranty, contact your seller for the details regarding warranty...No need to woory about this, this is a sommon problem for most of recievers

Audio Out Fixed/Variable


Is your subwoofer amplified or passive?

You clearly understand that you need to use a variable line out to control the subwoofer volume via the TV. As the setup seems reasonable, I'm wondering if the subwoofer is getting a signal, but that it is at line-level and not internally amplified by the subwoofer speaker. Generally, if the subwoofer must be plugged into an AC socket in the wall, it has an internal amplifier and can be fed line-level audio. If it is "passive", it has no amplifier, and it must receive an amplified signal (over speaker wire) from an amplifier (or integrated receiver). TV's don't generally have connections to send out an amplified signal.

If the subwoofer is indeed amplified, then this is obviously not the problem, but it's the first thing to verify given the information provided.
