I have a panasonic HD plasma tv. It is about 5 years old. It will not turn on. And a red light next to the power button blinks 10x. Please help!


Try disconnecting all of your HDMI cables and plugging the power cord of the TV into another wall outlet. If this resolves the issue, you may have had a small power surge from either your wall outlet or one of your source devices. It is recommended to connect your TV to a surge protector if you haven't done so already.

Ac adapter is red, what should i do?


This problem occurs when the power supply detects a problem. The power supply has several built-in safeguards to help prevent damage to either the console or to the power supply. The power supply will turn off if:
  • There is too much current.
  • The voltage is too high.
  • The temperature of the power supply is too high.
When any of these things happen, the light on the power turns red.
Solution 1: Make sure that the power supply is cool loadTOCNode(2, 'whattotry'); The red light might indicate that the power supply is too hot or that it has overheated. Follow these steps if the power supply light is red:
  1. Turn the console off.
  2. Disconnect your Xbox 360 Power Supply from your Xbox 360 console and from the wall outlet.

  3. Let the power supply cool for two hours in a well-ventilated space. Do not connect the Xbox 360 power supply to the console or to the wall outlet during this time.
  4. After the power supply has cooled for two hours, reconnect the power supply to the console and to the wall outlet, and then turn the console on.
If the power supply light is still red, try the next solution.
Solution 2: Make sure that the power supply is plugged in loadTOCNode(2, 'whattotry'); Make sure that the power supply is directly plugged into a working wall outlet. Problems might occur with the power supply if it is connected through an extension cord or surge protector.

If the power supply light is still red after you connect the power supply directly to a working all outlet, try the next solution.
Solution 3: Plug the power supply into a different wall outlet loadTOCNode(2, 'whattotry'); To check the possibility that the wall outlet you are using is faulty or that there is a blown fuse, plug the power cord into a wall outlet that you know is working.

If this does not solve the problem, try the next solution.
Solution 4: Order a replacement Xbox 360 power supply loadTOCNode(2, 'whattotry'); If you've tried all the solutions above and your power supply light is still red, you should contact Xbox Support to order a replacement power supply.

To help the power supply work correctly, follow these guidelines:
  • Do not block any ventilation openings in the power supply.
  • Do not put the power supply on a bed, a sofa, or on any other soft surface that might block ventilation openings.
  • Do not put the power supply in a confined space, such as a bookcase, a rack, or a stereo cabinet, unless the space is well ventilated.
  • Do not put the power supply on a stereo speaker, an amplifier, or a heat source such as a radiator or a heat register.
  • Do not use an unlicensed accessory, such as a third-party power supply or any accessory that plugs in between the Xbox 360 console and the power supply.
  • Plug the power supply directly into a working wall outlet. The power supply might not work correctly if it is connected to an extension cord or surge protector.
hope this helps.

The ac adapter red light stays on and the counsole will not work


This problem occurs when the external power supply has detected a fault. The power supply has several built-in safeguards to help prevent damage to either the console or to the power supply. The power supply will turn off if one of the following conditions is true:

• There is too much current.
• The voltage is too high.
• The temperature of the power supply is too high.

When any of these conditions are true, the light on the power supply turns red. Here are some steps that you can use to try to fix the problem.

Step 1: Make sure that the power supply is cool

The red light might indicate that the power supply is too hot or that it has overheated. Follow these steps if the power supply light is red:

1. Make sure that your Xbox 360 console is turned off.
2. Disconnect your Xbox 360 Power Supply from your Xbox 360 console and from the wall outlet.
3. Let the power supply cool for two hours in a well-ventilated space. Do not connect the Xbox 360 power supply to the console or to the wall outlet during this time.
4. After the power supply has cooled for two hours, reconnect the Xbox 360 Power Supply to the console and to the wall outlet.
If cooling the power supply does not resolve the problem or if the problem persists, use the steps in the next section.

Step 2: Make sure that the power supply is plugged in correctly

Make sure that the power supply is directly plugged into a working wall outlet. You may have problems with the power supply if you use an extension cord or a power strip if the extension cord or the power strip is faulty or cannot supply the required power to the console.

If the power supply is still not working as expected, use the steps in the next section.

Step 3: Plug the power supply into a different wall outlet

To eliminate the possibility that the wall outlet you are using is faulty or that there is a blown fuse, plug the power cord into a different wall outlet in a different area of your place of residence.

If this does not resolve the problem, use the steps in the next section.

Step 4: Try another Xbox 360 Power Cord and Xbox 360 Power Supply

If you have a different Xbox 360 Power Cord and Xbox 360 Power Supply, try to use them to test the console. If the console turns on when you use a different power cord and power supply, you need to replace the faulty power cord and power supply. If the console does not turn on, the issue may be with the console itself.

If this does not resolve the problem, use the steps in the next section.

Step 5: Obtain a replacement Xbox 360 Power Supply

If the steps in this article did not resolve the issue and the Xbox 360 Power Supply light continues illuminate red, you need to obtain a replacement power supply.

let me know how you get on or if you need further assistance ok

plz rate this solution as i have a whole page of unrated posts, thanks

How to connect an Aiwa LX70 turntable to an Aiwa NSX-AV95 stereo system . The red and the white are fine where does the cable with the plug fit and where does the loose end wire fit ( i thought it was...


there should be a small round connector on the rear of the turntable for the mains transformer supply and the loose wire is the earth/ground connector which should be connected to the screw connection on the rear of your amplifier? just loosen the screw ( usually brass or steel ) on the back of the amp, wrap the thin earth wire around the thread making sure it has some exposed copper ie, strip a bit of the cable and then tighten it back up? good luck
