What kind of deck to you have? Sometimes there's a setting for the subwoofer output that has to be turned on. How is the deck hooked up to the amp? Be sure of the normal things: -Make sure the sub is connected in side it's box -Make sure the RCA cables didn't come off the deck -Check every connection! Let me know and be sure to leave feedback or I don't get paid.

SOURCE: Sony amp str-db940 - protection

Somewhere in your speaker wiring, you have a shorted wire. This short can be as simple as a single strand of wire touching the other terminal on one of the speakers.

With a bright flashlight, look carefully at the back of the receiver and then the speakers for any loose strands.

SOURCE: HOW TO WIRE AN EQUALIZER TO A SONY TA-FE370 AMP

You can't wire an equalizer to this amp unless you only want to equalize one source, because it doesn't have a tape monitor function.

Amp keeps blowing fuses


Blowing fuses, was caused by many thing.
Short of rectifier,resistor,elco,tube heater,tube pin, and also trafo itself (primary or secondary winding). It must check step by step.
CAUTION :
THIS IS HIGH VOLTAGE AREA.
RISK OF ELECTRIC SHOCK THAT CAN KILL.
DON'T DO THIS IF YOU ARE NOT TECHNICIAN OR NOT FAMILIAR WITH VACUM TUBE CIRCUIT. THE CIRCUIT MAY STILL CONTAINS ELECTRIC SHOCK EVEN IF IF THE AMP IS NOT POWER PLUGGED.


The simple steps (see picture) are:
  1. Disconnect all connection from secondary of power trafo (PLV,PDCH,PACH and PHV).
    Power ON the amp. If fuse is not blowing,trafo is good.
  2. Power OFF the amp. Unplug the cord.
    Connect PLV1-PLV2-PLV3 (this are Bias voltage,+/-15VDC and Backlight PCB voltage) to power trafo.Power ON the amp. If fuse is not blowing,PLV circuit is good.If fuse blowing,there are parts is damage (dioda,elco,7815/7915,resistor) in this PLV circuit.
  3. If step 2 is good,go to next step.
    Power OFF the amp. Unplug the cord.
    With PLV circuit stay connected,connect PDCH 1-2 and PACH 1-2 to power trafo. Power ON the amp.
    If fuse is not blowing,PDCH and PACH circuit is good and all tubes heater/filaments are lights after a few seconds.
    If fuse blowing,there are parts is damage (dioda,elco,tube heater pins) in this PDCH/PACH circuit.
  4. If step 3 is good,go to next step.
    Power OFF the amp. Unplug the cord.
    With PLV,PDCH,PACH circuit stay connected,connect PHV 1-2 to power trafo.
    Power ON the amp. CAUTION: HIGH VOLTAGE AREA is ON.
    If fuse is not blowing,PHV circuit is good.
    If fuse blowing,there are parts is damage (dioda,elco,tube pins) in this PHV circuit.

Notes:
  • Steps had to be done sequentially from 1 to 4, not upside down.
  • If tube/heater pin is short,it can't be repair. The tube must be replacing.
  • PDCH circuit is voltage for V1-2-3-4 heater/filaments.
  • PACH circuit is voltage for V5-6-7 heater/filaments.
  • Always replace fuse with same type.

I have an older creek 5350se. It has what appears to be bridging pins connecting the pre with the power sections of the amp. Can I connect the creek as a pre amp to a power amplifier.


Hi Lorne,

You can use the amp as a pre by removing the 'jumpers' - or as a power if required.

The 'jumpers' are simply used to connect (or disconnect) the amplifier's pre & power sections.

Hope this helps.

I HAVE A CANON IR 3300 MACHINE I HAVE ERROR E00000-000


WHAT: Either the main thermistor doesn't attain 30?C 1 second after the power switch is activated or it doesn't attain 70?C 2 seconds thereafter.

WHY: It has a faulty fixing film unit, lack of connectivity with the main thermistor, lack of connectivity with the fixing heater, a faulty main power supply PCB, or the DC controller PCB is faulty.

NOTE: You can reset the error by performing the following in service mode: COPIER>FUNCTION>CLEAR>ERR.

CONNECTOR FIX: Make sure that the connector of the fixing assembly is seated.
A. main power supply PCB (J8) relay connector heater
B. DC controller PCB (J320) relay connector thermistor

FIXING FILM UNIT (THERMISTOR) FIX: With a multimeter, check the interval between pin 1 & pin 2 & between pin 3 & pin 4 of the connector (4-pin) of the thermistor for electrical continuity. A result of ?? means that the circuit is open (lack of connectivity). Resolve this by replacing the fixing film unit.

MAIN POWER SUPPLY PCB, DC CONTROLLER PCB FIX: Press the Start key. If the drive voltage of the heater is supplied by the connector J8 of the main power supply PCB, then the main power supply PCB should be replaced. If not, then the thermistor control mechanism is faulty & the DC controller PCB should be replaced. Use the following to ascertain this:
Main heater: between J8-1 (FSR1) & J8-5 (FSR COM)
Sub heater: between J8-3 (FSR2) & J8-5 (FSR COM)

Cpu fan stop few second after starting pc


Hello,have you installed new motherboard or CPU?
Follow these steps again
1) Disconnect the power cord from the back of the computer & open up the case.

2) Wear an anti-static glove or at very least discharge your static by touching a metal surface or power supply

3) Disconnect the main 20pin ATX power connector from the motherboard & the square 4pin ATX2 power connector

4) Remove any PCI cards you have & disconnect ALL drive cabling from the MOTHERBOARD. Also disconnect any internal USB fly leads from the motherboard.

5) You should now have ONLY the cpu+heatsink/fan, memory & video card installed. Locate the round silver battery in the bottom right corner of the board. Just below it, you'll see a plastic jumper cap. This cap should be covering 2 pins (pins 1 + 2) with pin 3 bare. It will be marked JP1. Move the jumper to cover pins 2-3 instead. Leave in this position for about 30 seconds, then return the jumper to its original position (pins 1-2).

6) Reconnect the square 4pin ATX2 power connector & the main 20 pin ATX power connector. Make sure that the case speaker or buzzer is connected also.

7) Make sure the only external devices connected are the keyboard/mouse & monitor. Reconnect the power lead & power on the system

Let me know what happens

Sony amp has no power


There should be 3 wires running to the amp. +12v, ground and remote. ensure the remote is connect to the remote of the player or preamp. if the remote aint connected there will be no power on the amp.. if yor radio or player dont have a remote wire, connect the remote wire directly to the battery +12 to test it. If it powers on, then you can run the wire to a spst switch somewhere in the car and from the switch to the amp.

Check the fuese on the amp..

No sound


It's very likely that you have a factory amplifier in the vehicle that needs to be either turned on or (preferably) bypassed to get sound to the speakers. If your vehicle is a Mustang, it's almost certain that you have a factory amp. If the factory plug includes a long, 8-pin gray plug and a small, square 8-pin plug connected to a round cable, then the amp turn-on wire is at the opposite end of the gray plug from the constant power wire. This needs to be connected to the blue/white wire on the Sony head unit for the factory amp to turn on. Otherwise, if you dig into the radio cavity a little bit, you'll find a black 8-pin connector that looks very similar to the gray connector at the back of the radio. The black connector pins are connected directly to the speakers, bypassing the factory amp.
