My sanyo tv dp57040 wont turn on, the green light turns on for about 3-5 seconds and i don't know what part to buy. Can anyone help?

SOURCE: please help with tv! green blinking light wont stop and tv wont turn on

Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.
please post your error code

Try disconnecting the connector KBL on the main board as shown in my picture #DSCF0585 to see if the backlights will come on, if it does, the main board is bad.
Also check the voltages on the output connectors of the power supply.
