faulty power supply

The high voltage power of your tv is not working only the light indicator is working . you need this to bring to the shop to fix the power supply.

my screen will turn on right after unit is plugged in and stay on for a short period of time, then it shuts off and the red light near the power button blinks and teh tv will not turn back on. there might be problem of loose contact in power supply Thanks
