View Full Version : JVC RX-400 Receiver problem

05-31-2010, 06:02 PM

I'm a 53 yr old newbie. Am outfitting my garage with vintage equipment. I found some Bose 901's series 5, & am powering them with a JVC RX-400. Everything works great on the JVC, except the tuner doesn't work(doesn't even light up.) Any suggestions? I bought a Sansui TU-3900 Tuner & solved my problem, but would like to get the JVC up to snuff. I also have a Onkyo TX-84 receiver that works perfectly, but wouldn't the JVC be a better amp for the 901's?? I'm rediscovering all my old vinyl again!

I am confused by your terminology. You say the tuner doesn't light up. Do you mean the tuner section of the receiver, or the entire receiver?

I have a JVC receiver of about the same vintage and have had problems finding a service manual. I'd guess you would have similar problems. Mine is RX-703VBK.

You could repair that without a manual but that's the hard way.

The easy way is to check the fuse (if it has one), and open it up to see if there are any fuses inside!

Searched "JVC RX-400" and came up with a bunch of hybrid SUVs, sorry. Having no experience with vintage gear, I don't know whether the tuner is wired and powered together with the rest of the system (do you have a input select dial?).

Sorry Guys.

#1 the tuner section of the receiver doesn't light & no sound. So the fuses are located inside the cabinet(I see no fuse holder on the back.)?

#2 I have input buttons to push to select my source.

I downloaded a RX-300 manual(near mine) & have yet to read it all.

That is probably a microprocessor controlled unit and so the panel only sends commands to the digital circuitry. Check power supplies.

Is this the one with the backlit LCD display? That has the electronicly controlled EQ?

So basically, with no electronic knowledge & testing Equip. If fuses aren't blown, I should find a tech to look into my problem. Any opinions if the Onkyo tx-84 would be as good powering the 901's, or should i stick with the JVC??
