vizio e420vse
« on: February 02, 2013,20:52:41 »
i think i posted this in the wrong section.. here it goes again ..

 im having issues with the led backlight on a 42" vizio tv..

tv turns on ...  but no picture.. i do see that the vs is on when i shine a flashligt to the lcd... i checked for voltage on the led driver board.. i get the 25v in when tv is supposed to be on..

on the bl_on/off pins and the dimming pin.. i get 2.9 volts.. idk if thats the right voltage to drive the boards... but i do not get any voltage out on the vled1 and vled2 outputs to the led strips... any sugestions?? should i replace the driver board or is 2.9 volts too low of a votlage and thats why its not turning on?

any help will be apreciated thanks
