Assuming you mean power supply.......

Instructions
1
Check to make sure that your LCD TV is not plugged into any overloaded household circuit. Since your washer, refrigerator and dryer all use up a huge amount of electric power, complicated wiring may lead to multiple items plugged into the same circuit. Plug your LCD TV into its own power socket to test its power supply accurately.

2
Connect the power cord of the LCD TV snugly into the power source or socket. Make sure that all connections are snug including your DVD player or cable box. Test the socket that you are using by plugging in another electrical item to see if the current is flowing smoothly.

3

Inspect the power cord for any cuts or nicks. Replace any cord that may be damaged or bring it to an electric repair shop for rewiring.

4
Test the incoming flow of AC power by connecting your LCD TV to an independent power source. Your power source can be an Uninterruptible Power Source with your UPS cord removed from the power socket. If your TV works, this means that the power supply is in good condition.

5
Plug a lamp into the socket and see if your LCD screen flickers while testing your power supply. If the light of the lamp flickers, this means that you may have intermittent power fluctuations. In this case, you must contact an electrician to fix the problem to prevent fire hazards.
