Are you getting 12vdc at both ends of SMD fuse F21 on the integrated T-con board on the LCD panel when the backlights are on?

Re: vizo e320i-ao

i check the fues on the pannle borad if this is what your asking
i think you are asking this because the main has t-con built in it

the borad that goes to the pannel on bottom of tv is where i am checking now right
yes 12.09 on both sides when on an 0 when off
i check the vollt reg on the labe location ic5 i belive thats what it says
line1 =1117
pin1=.61
pin2=1.87
pin3=3.32
from reading about these volt reg it look right on
i am lost after that thanks

This model Vizio is known for BAD LED's inside the panel. I will check the voltage going to the LEDs connector. the voltage should be around +50volts when you power on the TV.

IF the voltage slowly fail to +19volts then you have bad LED(s) inside the panel

Re-read the thread. Backlight is working not an Led issue.

Re: vizo e320i-ao

Have you an Os scope to check the Lvds signals going to the panel ? Thats where I would start to see if the Mb is working.

Re: vizo e320i-ao

well i just got in a new/used main for this set an its doing the same thing
so i guess its in the pannel board
i have to look in to it so more
i do not have an scope so all i can do is check for volts on lvds cable an some are there i have no idea what volts should be there so i guess thats where i am at with this set i have the will to learn an if anyone know a way i shall try it
thanks for all the help as for this place rocks

Re: vizo e320i-ao

Yeah, one you take them off they are not going back on lol so doubt its worth doing. Too bad you dont have a scope could have found the issue on that display driver
