The red light is a power protection circuit designed to shut the amplifier down due to an overload or wiring problem. If the amp was playing then shut off, my guess is a problem with the speakers or the speaker wiring. Some amplifiers are only stable to a certain load. For example, most car audio speakers are 4 ohms which is the resistance placed upon your amplifier to produce a certain volume of sound. If you bridge two 4 ohm speakers together in parallel, you cut the resistance in half, thus increasing the amount of power (and volume) to your speakers. This also creates more heat and could, in effect, shut your amplifier down. I would find out how the speakers are wired to determine the resistance of the load your amplifier is pushing. Also check the grounding.

Is it ok if my PNY 16GB flash drive is flashing red but working fine?


You should first read the documentation to see exactly what the flashing read light means. It could mean that the drive is near full capacity. Try removing/transferring a few files to your hard drive to see if the flahing read stops. As long as it works ok, I wouldn't be too concerned.

Hello! I'll need the trouble code to fix your vehicle...Below is procedure with a code list...Guru...saailer

Remove the trim panels in front of the center console. Locate the engine computer attached to a floor-mounted bracket on the transmission tunnel between the console and the firewall.

  • Turn the diagnostic mode selector, located in a round opening on the side of the engine computer, until it stops. Observe the small red and green LED lights on the side of the computer next to the mode selector. They will flash to indicate the modes, with a pause between each mode. One quick flash is mode one, two quick flashes is mode two and so on. When the light flashes indicate mode three, quickly turn the mode selector counterclockwise until it stops. You have entered mode three diagnostics.

The red light flashes to indicate the "Tens" digit of the code and the green light flashes to indicate the "Ones" digit of the code. For example, if the red light flashes two times and the green light flashes seven times, this would indicate code 27.


    Turn the ignition key off for two minutes to exit diagnostics. The computer will automatically return to mode one for normal operation...

    E73 Error


    Error E73: General Hardware Error: Ethernet port... this error is caused by a problem with the Ethernet port.

    This error is also caused by a cold solder joint under the Southbridge or the Ethernet chip.Can also be one of the solder joints that lead to the GPU.

    check if you are getting any flashing red lights on your xbox 360 power up button, if you are not getting any flashing lights the probably you may try unplugging any Ethernet cable attached if you had tried connecting to Xbox Live and at that time you face this error, re-connect and check

    If you still get this problem and you see a single flashing red light on your console, please send your console for repair to MS support if it is under warranty

    Miele g892 and just like everyone the red light comes on and dishwasher stops running> why cant you answer thic common problem>


    The red light tell you there is a fault. You have to read the fault code and it will give you a general idea of the problem - to do this you have to enter the service mode of operation - close the door and turn the dishwasher on.
    The Start/Stop light must be blinking. If the Start/Stop light is not blinking, press and hold
    the Start/Stop button for at least 3 seconds to exit the cycle. The Start/Stop light should now be blinking.

    Press and hold the Start/Stop button while turning the dishwasher on. Release the
    Start/Stop button and immediately press it 2 more times. Flashing Intake/Drain and
    Salt lamps and a lit Rinse lamp indicates successful accessing of services mode

    The TV shutdown error code can help you with this problem. If the power led flashes green for 2 Min's then red. The Lamp led should flash red 1-2-3 or 4 time every 5 Min's. These are error codes that may point you in the right direction to you problem.
