Sound cuts out frequently for a few seconds

You Need to Change Wire Connected to Speakers. it's may be damaged internally.

Could be a bad solder joint inside the unit you have to tap.

The steps I would take to check it out are as follows:
1) Make sure that your computer isn't causing the issue - there are a number of software and OS issues that can cause spotty playback (do you have a lot of programs running at the same time? do you never restart your computer? does the cable fit in snug, or does it jiggle?)
2) Replace the cable connecting your computer to the mixer. If the computer is outputting properly, intermittence is almost certainly a cable issue.
3) If that cable doesn't solve it, try replacing the speaker cable. Though, if you're using more than one speaker and they both cut out at the same time, it's unlikely that this is the issue.
4) If you still are having troubles, it's probably a loose connection somewhere in the mixer. Contact Fender about getting it repaired.

Sounds like solder connections on the output ic. Get it fixed before its too late...cost 50 to 75

you tried switching wires. maybe its your ps3. dont think you can return those can you?

If this is a flat panel sony LCD--probably a bad CCFL inverter.

Go to Sony website and download the newest firmware for your tv

try plugging into the 3rd port
