Jvc rx-805v repair

Hi, I have a jvc rx-805v receiver. It started crackling in the speakers and then the speakers went dead.The amps on it have blown twice in the past(overheated?)The first time they were replaced,they only lasted a year. the second time, they have lasted for a number of years. The second time cost me over $100. It is a good unit and would be costly to replace.I would like to save some money this time by replacing the parts myself. How do you determine which are bad? Where to get the parts? The parts are Toshiba 2sb1429 and Toshiba 2sd2155. Thanks. Regards, Chuck

Repairing amplifier is not easy as you think, one mistake could lead to more damage, simply replacing output transistor may not solved it, and may damage the new parts, very risky. If you are not knowledgeable on this task, don't do it. Amplifiers are the most risky gadget to repair especially the high-powered amps.

In my JVC RX 8SD only works a channel. How do I repair this defect?

Start with the simple things.
  • Check left right balance
  • Swap output speakers left to right
  • Swap the speakers at the receiver to make sure no wire open/short
  • Swap input RCA cables left to right red/white - white/red
Ok No JOY!
JVC has thermal overload circuits/overload on most of there Amps.

Remove power for a minute or two to see if there is a reset.

Rewire speaker connections to speaker set 2.

Connect REC out to Rec In swap cables and see if problem is in pre-amp or power amp.

Check internal fuses.

How much is a 1991JVC RX-805V worth now in 2010

hello. Sadly, 20 year old electronics have little or no value. There is no warranty and often no repair parts available. If you are looking to sell this item, offer it for $10.00 or best offer. J.

Jvc rx-805v repair (response)

Depending upon what parts are required, parts are still available for this unit. There are either direct replacements or substitutes available from generic suppliers. JVC may no longer supply the parts, but most electronics components are available.

Connecting Bose 901 Series VI Direct Reflecting Speakers to JVC RX-8020VBK Receiver

in order to make those speakers sound good (if they can sound good at all) you need to use equalizer box witch came with them. If your receiver does not have tape monitor loop or preamp to amp jumpers you can not use those speakers. To be honest you do not loose much... none of this stuff is any good (sorry for bad news), but if you like those speakers (I know they have big fans, even if in HI-FI world, they not consider as good) you have to change you receiver.

Stopped working

I had a similar problem with a jvc 8040. when I replaced the fuse it became very obvious that the b1560 output on the center channel was blown (smoke and sparks, always a dead giveaway). I haven't fixed the center channel yet but simply unplugged the center channel board and removed it from the unit. Now everything works fine except of course the center channel. Pre outs still operate just fine so a slave amp could be used for center channel power, or you could just go and buy a marantz amp; I did and then I realized that I was lucky that the old jvc quit.

Whenever I turn receiver on, it turns off almost immediately

The amplifier blew out (probably shorted and damaged when wire was loose, and gave out under load). It won't be cheap to repair....

JVC RX558 VBK, Crackling noise from speakers

A quick quess of mine is the following:

The OVERLOAD indicator lights up when the receiver is maxing out on the current it is sending to the speakers. My guess is there is possibly something wrong with the receiver itself, especially since the B speakers won't play. Either that, or something is broken in your speakers or you are using a set of speakers that have too low an impedance rating for your receiver.
