    what else blew when the outputs did?
    i think you have a more serious problem than just outputs.

Remove the outputs completely and start up the unit. Measure each of the pads to ground with a DC voltmeter and report the values here. I suspect that you have either an open driver transistors. Using the voltage readings, I should be able to guide you further.

How do i put my pioneer receiver to my cable tv,dvd. vsx-917-v-k


For this purpose I am using headphone output of the TV set. I connect the headphone output to the AUXiliary input of the receiver. All you need is an interconnection cable, one end with 3,5 mm stereo male earphone jack, the other end with a pair of RCA jacks. This output of TV provides an additional output signal to your receiver but volume control behaviour (independent volume control for earphone output etc.) changes for different brands of TV sets.

Got button happy on cable remote and now can't get sound back coming through the stereo receiver OR the TV internal speakers. Have been trying to get sound back for hours w/o success. Can you help? ...


Somewhere here you changed the input on your TV and or Pioneer. The TV audio output should be on the input of your Pioneer. Make sure that you change the input selection on the Pioneer to match where you have your audio input on the back of your Pioneer. So many of these devices have multiple inputs and outputs. They should be labeled on the back. Once you find that out you should then go to your remote and select the proper audio input from the menu. Let me know if that helps and we can try a couple other things. Also make sure your TV output from the tv is on to send it to the stereo unit.

How do i conect my tv to this receiver


That would depend on the capabilities of the TV.

The VSX-D509 manual is avalailable for free at retrevo.com.
http://www.retrevo.com/s/Pioneer-VSX-D509S-Receivers-review-manual/id/385ci970/t/1-2/

The receiver only needs a simple composite monitor output using a standard RCA cable so you can use the TV to operate it through its menus.

My TV has many video inputs of the various technologies, so I connect each Hi-Def video source's video directly to the TV and run the audio from them to the appropriate inputs on the Receiver.

If you feel the need to have the TV's minimalist audio run into the receiver just run an RCA pair from its audio output to any available analog input, but the sound will be limited to analog stereo. In the TV's setup find a setting for the audio output and select whatever closely resembles a 'fixed' level so you can mute or turn its volume down without affecting the audio out to the receiver.

I have a Pioneer Audio Multi Channel Receiver model SX-316-S and I can't seem to figure out how to hook up my TV and DVD to the receiver so that all sound comes through the receiver


DVD audio straight in from its highest quality audio output. Use the stereo audio output to run straight to the TV for casual watching through TV speakers without the Pioneer involved.

A TV is just a glorified night-light, not a sound source - get its related audio from the Cable Box, ditto the highest quality

Distorted sound in channel


PLEASE :) wear saftey goggles, no jewelry or watches while troubleshooting a live amp. Tube amps have up to 600V dc on some points so rubber gloves will improve the saftey margin. My primary suggestion is to take it to a pro. Please be safe if you are inexperienced. I can't be liable for my fixya suggestions.

I think you meant "changed" Left speaker with Right Speaker and visa versa. Some receivers have speaker A and B selections from a switch on the front, which is why I ask. I think you tried each speaker on the bad channel to find if the speaker was blown. If the speakers are OK make sure that the speaker wiring is good too. Sometimes they can be compromised so use two short lengths of new wire for trouble shooting. Try the other functions like tape, cd, phono, aux, dvd, ect. and if there is no problem with them then it is your tuning system. Check your antenna first. Make sure you are tuned to the station with max power received. Sometimes you can lose Stereo with analog tuners or be tuned to a harmonic frequency close to the target frequency. Check all of the fuses. Sometimes slo-blo fuses can blow incompletely resulting in a high resistance that causes a voltage drop. If the problem is still there you have trouble in the RF receiving/pre-amplification circuit or blown components in the output transformer/tube/transistor circuit. This is verified by having the same problem with the other functions above. In either case, you will need to take the unit to a repair service or get a service manual and test your voltage points to determine which components are bad. Without a service manual, I would start with the Left output transistor. Check the AC and DC voltages with respect to ground (chassis or negative output/input) on the good channel at all nodes and compare them to the same ones on the bad channel. Again, start with the output circuit for the amplifier. There will be one or more transistors per channel. They will be screwed to a heat sink. Also look for brown, cracked or melted components. Keep in mind that replacing these does not necessarily fix your problem as there is usually a failure elsewhere which caused them to go bad. Work your way back to the actual input signal and you will have hopefully found the problem. Good luck, be careful, and seek some local advice from your friends or repair technician. Happy Shooting!

SX-1600 + KD-491F


Hi again,

It would seem that you posted the problem here also. With your kind permission, I will repost my excerpts of my responses that others may benefit on similar concerns.

A. Most current receivers no longer include a PHONO input. Perhaps what could be done is to purchase a phono to line level pre-amplifier to go along in your purchase for a new receiver.

I was made to understand that the Pioneer SX-1600 is prone to speaker output problems which could either be:
1. the speaker relay (protection); and/or
2. the amp, STK4191II Stereo Module.

Either should be relatively easy to work on and perhaps you can try the services of a locally available qualified electronic technician since the repairs would not be too specialized. The service manual may be of help (or at least a schematic , they may be downloaded from here and here).

B. To recap what you need is a receiver that can accommodate:
4 - Pioneer S-DF1-K (15-100W, 8 ohms)
1 - Pioneer PD-F407 25 Disc CD Player
1 - Pioneer CT-300 dual tape deck
1 - Kenwood KD-491F turntable

C. Possible choices are (keeping in mind that the power output should be less if not equal to 100 watts and a turntable/phono input):
i. Onkyo TX-8522 Stereo Receiver;
ii. Yamaha RX-397 100 Watt Natural Sound AM/FM Stereo Receiver;
iii. Sony STR DE695 AV receiver;
iv. Teac AG-790 200 Watt Stereo Receiver;
v. Denon AVR 888 - AV receiver - 7.1 channel.

Some of the above also includes feature(s) to hook up to your video system. Some may even require a fifth speaker (subwoofer).

Incidentally, you can also choose another brand/model even without a turntable/phono input. As initially posted, a turntable/phone to line level pre-amplifier is only required. Here are some examples:
a. XP200 Turntable Preamp - Nano Series;
b. Pyle® Pro PP999 Phono Preamplifier;
c. Pro-Ject Phono Box Turntable Preamplifier;
d. Radial J33 RIAA Turntable Preamp Direct Box

Good luck with your project.

Pioneer rx570 just quit ? any help? power in the house went out maybe a powersurge worked fine lastnight came home today and had to reset the clocks blythkid39@yahoo.com


Hi blythkid

Your unit has probably popped a mains fuse in the power up down. If you are keen, disconnect the unit from the power and take the lid off. Check for any blown fuses and replace with EXACTLY the same type. If you are not sure what the correct fuse is... get back to me here and I will help you further. Good luck

Pioneer VSX-505S Subwoofer Installation


That type of subwoofer is not used with this receiver. This receiver actually outputs no power for a subwoofer, therefore only needs a plain ol' rca signal wire. This is due to the fact that you need a powered sub... one that you plug in to the wall and it has its own built in amp. you simply run an rca from yyour 505s to that sub.
