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

Re: jvc rx-805v repair

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.

I have a Yamaha RX-385 receiver. I want to increase the number of speakers I can use from the receiver. I am considering buying a speaker selector that says it can connect 4 sets of speakers I can run to...

This speaker selector is standard accessory equipment for home audio equipment -- just follow the instructions with the unit.

The speaker selector unit has circuitry which prevents the amp from being overloaded by connecting too many speakers in parallel to the receiver. The receiver will have to be run at a higher volume level to drive all the additional speakers at the same volume as two sets of speakers, but this will not damage the amp in so doing.

Crackling noise in the rear right speakers often...

Try connecting another speaker that is known to work to the Rear right connector, and if the crackling noise still appears, it is a problem with your wiring, receiver speaker terminal, receiver internal board, or the device connecting to the amplifier or the wiring from that device to the amp. Usually this is a wiring problem, or faulty crossover.

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.

I would like to know how to connect my Bose 901 to my Yamaha RX-V765 AV Receiver.

Ahhh, the good ole Bose 901. (I like those)... And you want to connect them to the Yamaha RX-V765 AV receiver. That should be a piece of cake. I assume you only have two Bose 901 cabinets. If so, you simply need to connect one end of your speaker wires to the terminals found on the 901 cabinets, and the other end of the speaker wires need to go to the Front Left and Front Right speaker outputs of the RX-V765. The RX-V765 is a 7 channel surround receiver. Weather you run it as a 7 channel theatre or as a more classic 2 speaker configuration, you will want to run the 901 cabs from the Front L and Front R speaker outputs, unless for some reason you want to specifically use them for any of the surround channels in which case it will not harm anything if you use them for surrounds - it's just that if you're simply wanting to use them as your principal speakers, you want Front L and Front R.
So connect them as I explained, power the receiver up, put on your favorite CD and enjoy!

Static in speaker even after cleaning an plugging wire back in still crackles?I belive the speaker is blown.

fist test all speaker using different good working amp, so we can eliminate bad or blown speaks. second, make sure you hook up the right pole negative to negative and positive to positive, it very important that you do, otherwise you will short the unit real quick. next take the cover off the amp, get your self couple of can of dust cleaners and blow all the dust out real good. if everything is done and hook up properly than your amp is faulty. if you have no electrical back ground take it to the earnest electronic repair and have it done correctly.

Hi there.
Check for shorted speaker wires on left channel. If not, disconnect speaker wires and check to see if headphone jack works. If left works, you may have a blown speaker. If left still doesn't work, left power amp blown.

Blown fuse no sound in one channel

The only way this could happen is either the wires touching or a capacitor overheating and shorting out, Also hardly bumped or dropped would cause loose solder connections. Wich you should check eitherway
