My Coby flatscreen only turns on sometimes.

When I click the power button, the power indicator led gets brighter and I hear a whistling noise, then the led dims again and the whistling noise stops... but SOMETIMES the TV does come on.

But when it does, it recognizes HDMI cables as DMI and I can't use it.
