Speakercraft infrared system with AT-1.0 Amplified Terminator, IRC-1.0 Receiver, PS-1.0 Power Supply and IRE-3.0 Emitters. Not functioning - no light on the Receiver and no lights from the emitters when remote is pushed. Verified power from outlet and verified remote is functional. How do I determine if the defect is the Power Supply, the terminator or the receiver? Does anyone know if the receiver is powered by a battery or power from the supply going into the terminator?

You can't do this. The SpeakerCraft is a standalone amplifier. The Yamaha is a Receiver and has its own amplifier. Putting amplified sound into a data input is not recommended and will cause component damage and overload 'clipping'.

I deleted the two answers from AI Answer Bots as they are not doing you any favours suggesting it can be done in their waffling answers!

"My Yamaha receiver RX v575 will not power up it has a blinking red light when trying to power up "
Never press power button more than 3 times. Your amp will be locked, otherwise.
(1)Download RXV575 service manual.
(2)Read P.25 to 29 to see if protection occurs.
(3)Read P.31 and follow the diag steps.
(4)If I protect, check all power transistors,two
0.22Ohm resistors and biasing circuit such as
all components connected to Q2022 of front L channel, on P.108.
(5)If dc protect, check if DC comes out from speaker terminal, opening metal cover required.
(6)If thermal protect, replace a thermal sensor.
(7)If power supply problem, ps prt, check all
power supply circuits, including regulators and
caps.

red light indicates that your tv is getting 5V. supply from power supply. but it does not indicate that microcontroller which is responsible for functioning of tv is working. if you are a technical able person then you can check micro controllers' power supply, its oscillation, its reset voltages, its key matrix, & infrared receiver. so you will be sure where the fault is. or you may call an tv repair expert.

Hi:
You may have a problem with the inverters in the unit, they are responsible for lighting up the back panel. Check or have checked the power supply voltage to the inverters, should be around 18-24 volts DC. Also leaky capacitors on the power supply will cause this issue as well as leaky or puffy capacitors on the inverter.

If none of the lights are coming on for the amp then the amp is not getting power and/or ground. Check the connections. Check the fuses. Or the amp is no good.

Here is another post that describes how to test to see if your IR emitters are working. In addition, it steps you through the process of replacing the emitters on the Harmony 880. Although you have a different model, you may be able to pick up a few tips from this article. Good luck!

I can not locate a Remote For PS3 By Gigaware now if its a controller Follow these steps

Connect to PS3
1. Turn on your console and plug the receiver into the first port on the console. The RX indicator on the receiver flashes.
2. Slide POWER ON/OFF to ON to turn on the controller. The controller’s POWER indicator lights and the 4 port indicators flash.
3. The controller connects with the receiver automatically after about 3 seconds. If successful, the RX indicator on the receiver lights.
4. Press the PS button to assign a controller number. The corresponding port indicator lights.
Manual Search
If you are unable to automatically connect, try manual adjustment.
1. Repeat steps 1 and 2 under “Connect to PS3.”
2. Press CONNECT on the receiver. The RX indicator flashes.
6
3. Press and hold SELECT and L3 (left analog stick) on the controller simultaneously for at least 3 seconds. When the RX indicator stays lit, release SELECT and L3.
4. Press the PS button to assign a controller number. The corresponding port indicator lights.
n Notes:
• Repeat “Connect to PS3“ or “Manual Search“ if the connection fails again.
• If you purchase a new receiver for the controller, but have previously been using it with the supplied receiver, you will have to follow connection steps again.
Reassigning a controller number
1. Press and hold the PS button for one second. The functional screen displays. Select “Controller Settings”, then “Reassign the controller.” Press X to confirm.
2. Use the D-pad to select the number that matches the controller’s port.
3. Press X again to confirm. The corresponding port indicator lights up.
7
Connect to PC
1. Plug the recevier into a PC’s USB port. The receiver’s RX indicator flashes.
2. Slide POWER ON/OFF to ON to turn on the controller. If connection is successful, the RX indicator on the receiver lights and the 4 port indicators on the controller turn off.
Test the controller
1. Open the control panel on your PC, and double-click “Game Controllers.” Then click “Properties“ and the testing screen appears.
2. Press the buttons of the controller. After testing, press OK to exit. You are now ready to play games.
Troubleshooting
If the controller stops working at any time, or will not connect to PS3 or PC, follow “Manual Search“ steps on pages 5-6.

Sounds like its a problem with over heating. open unit clean out all dust and dust bunnies wich compressed air. check that all fans are opperating. (fans on 6x100 amp units or thermal controled). If amp goes into protection prior to fans turning, there is your answer. the @ power supplies will have a green light on the output side. if the light in on power supply is good. or you can check that the output voltage is at 48Vdc on both units.

The power supply board or inverter. The power supply board is the first step. Look for any capacitors that are puffed up. Replacing them should take care of the PS. Check to see if you have 24 volts going to the inverter. If you do PS is OK and the inverter is most likely bad...good luck
