I HAVE REPLACED THE POWER BOARD. STILL WONT COME ON. CHECKED THE CIRCUITS. YES POWER IS TO THE BOARD. COULD IT BE THE SIGNAL BOARD?

Hi Pam,

For a TV to come on, the power board has to send 'stand by or SB5V or 3.5V ' to the main board. On your pressing power on button on remote control, the main board sends power on command to the power board which in turn produces all the necessary supplies to run the TV. If the main board does not respond to your TV on command, the TV will not work. So It is not the power board which is responsible for not powering on of a TV every time. A voltage investigation before changing boards is always helpful. I hope it helps.
