Question about JVC RX-668V Receiver
Hi, Here's my setup. JVC RX-668V A/V Receiver. JVC XV-FA95 DVD player (7-disc changer). JVC TD-W354 Dual Cassette Deck. JVC XL-F254 CD Auto Changer (5 disc changer). RCA 32-inch Entertainment Series Television. Comcast Digital cable box hooked in there too. Very short version of below is the Center channel of the receiver doesn't work, even though I can hear the analog hiss indicating it's powering up. Here's the full details. I've only watched DVD's a few times on it where the DVD Multi function was enabled on the receiver. In the past, I didn't have problems when using the Center speaker. I recently started to watch DVD's on a regular basis, and I've encountered a problem with the Center speaker not playing audio through it consistantly. If I crank the volume up all the way (with only the center speaker plugged in), I can hear distorted but audible audio. The last few times, if I turned the receiver off/on a few times or switched in and out of DVD Multi mode on the receiver a few times, it would eventually kick in and be working fine. However, this no longer works, and I can't get the center channel to kick in all the way. The rear and left/right channels work perfectly. Now, I went through a ton of troubleshooting already, and have determined it is not the DVD player OR the speaker; it's the center channel on the receiver. I can get the center speaker to work perfectly when I plug it in one of the other channels on the receiver. Same with the DVD's center channel plugged into another channel on the receiver; works perfectly. I THINK I have gone through all the settings on the receiver as far as center channel volume and making sure it was enabled. There's all the other settings (hall, theatre, pavilion, etc) and I cycled through all of them with the "surround" button on the receiver. Any advice on what it could be? I'm thinking it might be a bad capacitor in the receiver, or some kind of goofy routing problem when the DVD Multi-function is enabled. I have no other problems on that receiver or any of the components attached to it. I apologize for the lengthy post.
Have a tech check your set it is a bad cap that that bias a very small voltage to that circuit or it could be cold solder.good luck.
