Customer Question
I have a 2005 Vizio...
I have a 2005 Vizio TV Model L-32. I have replaced the power board and also the main board. The standby light comes on but the tv will not turn on. 5v voltage to main board seems to be ok. Tried to turn on manually and also with remote but no results. Remote lights up when the power button is pressed. checked all connections several times. Also waited at least 5 minutes after powering up before turning on. Any thoughts ?

Hi Warren,

First, test the power supply board using a voltmeter to confirm the voltage outputs are as expected.

Reply back and let me know the results...
