You need to check the B+ and remote voltage on the amp when it cuts off (assuming that you can recreate the fault).

With your multimeter set to DC volts and the black meter lead on the ground terminal of the amp, touch the red lead alternately to the B+ and remote terminals as the amp shuts down. If the voltage drops below ~11 volts, you need to check the wiring feeding whichever line is dropping too low.

Why does my Hobart 30 quart mixer cut off after 15-30 seconds of mixing?

The small button that pops out is your over load protection for the electrical motor
There might be a phase missing from your power supply.
The motor might have a problem.
Or the gearbox is faulty and couses the motor to struggle to turn and thst is the reasons for a over load protection to trip

Pop the back off, unplug the battery for about 30 seconds, plug the battery back in, put the back cover back on. You will find it will start no problem.

The engine cut out then right away was running again then 20-30 seconds later completly cut out again. After a few minutes it started again and ran for another two days. Then it cut out again, ran for...

- When was the last time this car had a tune-up? Could be as simple as that. New spark plugs/rotor/distributor cap/condenser might do the trick.

Other causes could be:
- bad fuel pump relay (definitely first on the list of things to check, and cheapest to fix)
- clogged/old fuel filter
- bad fuel pump

Popping & hardly any volume

i had the first problem and you can probably fix it by turning the volume knob all the way up and down about 20 times. it worked for me. supposedly the potentiometers in the z-5300 get dirty or worn out, somehow this might fix it. for the second problem maybe try plugging it into the laptop and unplugging it again seeing if it goes back to normal?maybe its a problem with the amp?

Memory repair

Did you get a pop-up that said the repair was successfully completed? If not, then try the following repair instructions:
1) Open up Philips Device Manager (Start --> All Programs --> Philips) - if you don't see it, then re-run the installation CD or grab the "Device/Firmware Manager" from the Philips website
2) Click on the Repair Tab, and look for a msg that says connect the player while holding the volume + button
3) Disconnect the GoGear from the computer and turn the GoGear off (if you haven't done so already) - hold in the volume + button and continue to hold it as you reconnect the GoGear to the computer; after holding the volume + button for up to 20 or 30 seconds, a window will open up saying that your device is being repaired (now you can let go of the volume + button); after the repair is successfully complete, your GoGear will be good as new.

After this, you may be able to go back into Device Manager and click the Update tab to get the firmware upgrade which solves the memory corruption problem.

The coby speaker accident

Make sure you back up all songs on the GoGear before attempting this solution.

1) Back up all files on the GoGear
2) Open up Philips Device Manager (Start --> All Programs --> Philips)
3) Click on the Repair Tab, and look for a msg that says connect the player while holding the volume + button
4) Disconnect the GoGear from the computer and turn the GoGear off - hold in the volume + button and continue to hold it as you reconnect the GoGear to the computer; after holding the volume + button for up to 20 or 30 seconds, a window will open up saying that your device is being repaired (now you can let go of the volume + button); after the repair is successfully complete, your GoGear will be good as new

Now you can do the firmware upgrade that will prevent this problem from occuring in the future. Open up Philips Device Manager and click the Update tab. This problem was caused because most GoGear's were designed for Windows XP with Media Player 10 (which is no longer the latest standard).
