Power leak causing overload on the O/L sensor.

Sounds like the problem could be in the power supply of the TV. Have a technican check for defective capacitors if you're not equipped to do the job yourself.

What color is the power light when the system shuts off?
    Red: If the power light is red, or flashing red, when the system turns off, then the system's battery needs to be charged.


    Blue: If the power light is blue when the system turns off, then there appears to be a problem with the system and it will need to be repaired.

    If the orange recharge indicator light blinks while the system is plugged in and charging, then it is likely that the battery is not installed properly.

    If you have ensured that the battery is installed properly but the orange light still blinks, check to make sure that the battery is a licensed by Nintendo. The only licensed Nintendo DSi battery will have the model number "TWL-003" (Nintendo DSi) or "UTL-003" (Nintendo DSi XL) and will display Nintendo's logo.
    Call 1-800-255-3700 if you still need help.

On Pwr up logo appears then LCD returns to stanby Black screen


I will assume the monitor is staying on during the boot process all the way until Windows loads.
If that is the case, then...
  • Start the computer
  • wait until the initial bios/logo screens for your motherboard go away.
  • Press F8 to get the Windows recovery boot menu
  • If you see the Windows Logo you would normally see then press rest and try again.
  • In the recovery screen, select SAFE MODE
  • Boot into Windows and uninstall your video card.
  • Reboot the computer the normal way through the start menu.
  • When your PC starts back up it should then reinstall the video card, and set itself automatically back to 60khz as default.
Let me know how you go =)
