I have a Pioneer VSX-305 receiver. I blew channel A speaker outputs by allowing speaker wires to touch. Everything else works. Can anyone tell me what it takes to fix this. (I am an electrical engineer...


Without a Sams Photofact or a service manual I would go directly to the Power IC which is the largest Integrated Circuit mounted to a large heat sink. If you see any fuses they are probably for the power supply since any fused circuit on the speaker output would be ineffective because the IC would be damaged before the fuse would blow, but you need to check them anyway. Since the short was at the speaker output your problem should be at the final stage of amplification, which is the Power Amp IC. Prior to the early 70's you would have transistors mounted to a heat sink which could be individually checked and replaced. Then manufactures started to use the Power Amp IC which are more costly but eliminate having to find matched pair transistors. All you can check on the Power Amp IC is if you have an input using an oscilloscope or signal tracer and the power to the IC. If you have an input signal and power to the device with no output, I would replace the IC. Unless you have a test circuit for the IC you cannot test it completely unless you have a device like a Huntron Tracker or build a test circuit using a signal generator and a power supply to measure the gain of the IC with an oscilloscope. Short of ordering a service manual this is a good place to start.

I have presently a atx 350w power supply would yours solve my supply problem


If your ATX switch mode power supply is faulty then I suggest you replace it with a new one that is 350 watt or higher wattage.
Fixing faulty ATX power supplies is not a DIY project, there are dangerous voltages in these power supplies and can cause death or serious injuries.

Whos power ic?


The power ic is an integrated circuit (IC) that supply power for your TV.

ATX-300-12Z was hit with a power surge (thought we had a surge protector). Green light on power supply blinking at 2X/second. No power at USB devices (or anywhere else.) PC was on when surge hit.


There were 2 Switching power supply circuit inside the ATX PSU. There's a Standy PWM circuit whichSupply +5V to the PWM IC of the Main PWM. Stand by pwm still working or insufficient voltage, lower than +5V. This is the reason you still have Green light. Check or replaced small filter capacitor around 100 MFD 16V, open resistor or shorted diode that was nearest of the PWM IC..
Watch out for charge voltage on big capacitors.

When I push the startup button, the green light turns on the cooling fan start's just for an instent and shuts down. Even the Green light on the back of the computeris now turnes off. Any idea's to fix...


hshorty,

When you press the plastic Power On button, it in turn presses against a Power On switch.
The Power On switch is located inside the plastic Power On button.

This is an example of a generic ATX Power On switch,

http://www.directron.com/atxswitch.html

The switch completes a circuit.
(The Power On switch is a Momentary Contact Switch. Makes a brief contact, then opens back up)

The circuit the Power On switch completes, is the 5 Volt Standby circuit.
When a Power Supply is plugged into power, there is a constant 5 Volts (DC) present.
Closing this 5 Volt Standby circuit, momentarily 'excites' the Power Supply, and turns the Power Supply on.

Power goes to the Motherboard, and Peripherals, (Harddrive, optical drive/s, and so on)
The first chip to receive power is the BIOS chip.
(Chip and Chipset are slang terms for I.C. Integrated Circuit)

The BIOS program on the BIOS chip, looks to see what devices are installed, does a Ram Memory count, TURNS the Processor on, and hands the computer over to the O/S.
(O/S = Operating System. Windows XP is one example of an O/S)

Your Power Supply doesn't even have enough power to light those LED lights, much less turn the Processor on.

A) ALL the LED lights together, use less than 1 Watt of power.

B) EACH fan uses 2 to 3 Watts.

C) A typical Processor can use 51 to 125 Watts. Depends on what Processor it is. (Older Processors use less than 51 Watts)

If this problem is in reference to a Compaq Presario SR5130NX desktop computer, it comes with an Athlon 64 X2 - 3800+ Processor.

(Windsor Core. Also this Processor uses an AM2 processor socket)

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01048297&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&lang=en&product=3436820

This Processor can use up to 89 Watts.

http://en.wikipedia.org/wiki/List_of_AMD_Athlon_64_microprocessors#.22Windsor.22_.28F2_.26_F3.2C_90_nm.29

Fans start to spin, and the LED power light is on for the Power Supply. When it's time to turn the Processor on, too much power is needed, and the Power Supply 'drops to it's knees'.

The Power Supply used is just a common ATX style of power supply. (Actually it is an ATX 12V 2.x)
Used in a LOT of personal computers out there, and is readily available.
It's a 300 Watt unit.

(The ATX form factor for this Power Supply, (Size and shape), is approximately 6 inches Long, 6 inches Wide, and 3-1/2 inches Tall)

Power cables from the Power Supply needed are;

A) 24-pin ATX main power cable (Main power cable to motherboard)

B) 4-pin ATX +12 Volt power cable, (Also known as P4)

C) At least one SATA power cable for the SATA harddrive, and additional SATA power cables, for each SATA optical drive.

(Your Presario may have come with SATA optical drive/s, or IDE {PATA} optical drive/s. Optical drive = CD/DVD drive)

D) If your Presario came with IDE, (Also known as PATA), optical drives, you'll need a standard 4-pin Peripheral power cable, for each drive.

E) The computer case fans, may each use a standard 4-pin Peripheral power cable. (The Processor fan attaches to the Motherboard)

F) The Memory Card Reader needs a Floppy Drive power cable. An auxiliary power cable.

An example of a compatible Power Supply,

I would lke to know the reference code on the audio out put ic, used in the VHF MARINE IC-M302.


Quick description as per ICOM Manuals:
Quote
The AF amplifier circuit amplifies the detected signals to drive a speaker. The AF circuit includes an AF mute circuit for the squelch. AF signals from IC1 (pin 9) are applied to the de-emphasis circuit (R61, C89). The de-emphasis circuit is an integrated circuit with frequency characteristic of –6 dB/octave. The integrated signals pass through the high-pass filter (Q5, R62–R67, C90, C91) to suppress unwanted lower noise signals. The filtered signals are applied to the AF mute circuit (IC7B), and then passes through the [VOLUME] control (VR board; R1) via the “VOL1” signal. The signals are applied to the AF power amplifier (IC6, pin 1). The output signal from IC6 (pin4) drives the internal (external) speaker.
Unquote
I thus assume the IC you are looking for is the IC described as IC 6.
Data sheet availible online: http://www.datasheetcatalog.org/datasheet/sanyo/ds_pdf_e/LA4425A.pdf
The IC is a Sanyo LA4425A. A 5W Power amplifier.
