    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.

Check to make sure the speaker wires are not shorting, if no change! the problem is in the audio output ic, it will need to be serviced to solve the problem.

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

Output Chip blown, need help!


Why do you think the output chip is blown? This is NOT a user serviceable part. One must posess several uncommon tools, and must know what the output chip looks like.

There IS a chance that the radio is in SELF PROTECT MODE becausea speaker in the car is causing a direct short, or even possibly VERY HIGH, or VERY LOW resistance.

One at a time Disconnect speakers while the radio has a CD or station tuned in. If you disconnect the "blown speaker" the remaining speakers left connected should start to play.

Pioneer amplifier


Below is a list of all of the older model Pioneer amplifiers; your's isn't in it. I don't think you have a real Pioneer product but rather a knock off amp. If you locate the model number below you can follow this link to locate a manual for it: http://www.pioneerelectronics.com/PUSA/Support/CarAudioVideo/ch.Amplifiers.Archived?vgnextfmt=Archived

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.

for audio system always you have left and right channels.
get the output (left&right) from tuner---go to equalizer input left&right.---from equalizer output go to amplifier inputs.and certainly from amplifier output to speaker.
