Hi, I recently replace nonworking Vizio SV320M mainboard with a working one and now the remote control nor the buttons on TV don't function at all. After pushing power button on TV, TV turns on and I can see one channel is playing on TV but none of the buttons work. I can't do anything. Is this a mainboard issue or need a some kinda code or something? Any advice will be appreciated. Thank you.
So the power button is the only one that functions? Double check your main board, IR sensor, and key controller connections. You should not need a code at all. The only programming you should have to do is to do a scan for antenna channels you may use as well as setting up any of your personal preferences. Did you order the exact part # as the old one?

why should i tell you (fixYa) how i fixed the problem for free? You wanted to charge me for your info so i think it's only fair that i charge you for mines. I did figure out and solved the problem.
SOURCE: only vizio light come on then nothing. have to unplug to turn off
there a problem on power side.. chage the ic and the resistor going to ic and check also the signal diode.
