    Sony Muteki with USB Fail message or turning on and off is generally related to a faulty mains input relay. Search for it in the schematic and replace with a stronger part. Sony uses a very weak relay to connect the mains after power button is pressed. It doesn't last to much.

SOURCE: my sony bravia tv is flashing red stand by light

Try leaving the TV unpugged for 30 minutes so the TV can reset itself.
If that doesn't work, most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you flashing red light codes, circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

SOURCE: Proview LCD TV is turning itself off inconsistently.

I don't know about your particular tv, but most of the LCD tv's have a power off option that it will turn off after 3 hours of no activity.

Why it would turn itself off at 3 and 30 minutes is beyond me. But I did want to write so you can check your settings to see if maybe someone has programmed in some shutdown times or something.

Hope this helps at least some. Good luck!

SOURCE: Unit keeps turning itself off.

This Unit is a LCD Rear Projection and most likely the Lamp is causing the problem. I would replace it with a Sony Lamp only. You can order it from Sony at 1800-222-SONY.
I hope this helps,

SOURCE: 8 month old Symphonic 20 inch lcd tv turns off itself every 3-5 seconds

these sets that shut down or turn themselves off after a few seconds usally have a bad backlite board in them. look closely at the screen and see if one section looks darker than the rest of the screen (top middle or bottom - top seems most common in my cases). some times if you put the tv on an unused input you can see the variation of light level on the screen, but don't get confussed by looking at the screen from too great of an angle. thanks ......techman 580-243-8025

Sony Muteki 7.2 USB Fail error, no USB plugged in

Muteki 7.2 I turn it on and it read 'USB FAIL'


It is such a hassle when your USB port doesn't seem to be working or when it does not read what's connected to your computer.
You might have a speaker, microphone, keyboard, mouse, webcam, digital camera, joystick or printer that are connected via a USB port.
You are sure you have the device properly connected, and you are confident all gadgets are working well, but still, you can't seem to make it work.
Initially, you need to plug and unplug the device to see if the connection is loose.
But if it still does not work, there are simple steps to fix your USB port.

Shut down the computer, then turn it back on to make sure the device (speaker, microphone, keyboard, mouse, webcam, joystick or printer) is properly connected.
Right click on "My Computer" and choose "Properties."

Click the tab that says "Hardware."
Choose "Device Manger."
Look for "Universal Serial Bus Controller" and click the plus sign before it.
Check if anything has a yellow question mark.
Having a yellow question mark means Windows has detected a problem.

Find your initial installer CD for your PC.
Place it in the CD drive, double click the USB drive and click "update device," and the driver will automatically be updated.

W 7
First, please disconnect all USB devices and then perform the following steps:
Click "Start" button, type "devmgmt.msc" (without quotation marks) in the "Search" bar and press "Enter". Click "Continue" if necessary.
In Device Manager, double click to expand "Universal Serial Bus controllers", right click on the Host Controller, click "Uninstall" and click "OK".
Repeat the step 2 to uninstall all items under "Universal Serial Bus controllers".
Then, restart your computer and Windows 7 will reinstall all USB controllers automatically.

Will the Muteki sub amp work with a different receiver that has no trigger.


My subwoofer recently burnt out because I had it plugged into a different amplifier.. I wouldn't recommend it. Sony has released the sub to suit that system.. Do keep in mind that I did have bass boost on with the sub up full (Which didn't matter when I had it connected to the Sony amplifier..).

Proceed with caution.. I would recommend turning the sub down and using the sub volume control on the amplifiers settings to change the volume.. Just do not run it at a pace where it looks like it is stressing.. When I say stressing I mean, looking like it is going to jump out of the enclosure..

If a fuse blows it won't self-heal when you cycle power.

Swap the subwoofers between the two subwoofer speaker feeds. Maybe it will stay with the channel or maybe it will follow the speaker and make next steps easier.

Sony 46" lcd turns off by itself and will not power up again.


Sony TVs come with a one year warranty on parts and labor. Call Sony at 1-800-222-SONY They will find a local company to service this product.

These TVs have a self-diagnostic screen that a tech can access to help solve the problem. Your problem could be any number of things including the fan(s) stopping, the ballast board failing, Q-box issue or none of the above.
