How do I know what board is causing vertical lines?
It's actually the panel that's bad, not the board, one of your clock lines are shorted but it can be fixed with a piece of scotch tape by masking off the correct clock line, there should be 8 of them and it will give a decent picture just using 7, there are some youtube vids that describe how to find the pin to block if you want to dig into it.
D65u-d2 black screen diagnosis
Hi,
I would have attempted a system software update first once the screen went black. I would also disconnect all accessories. Then, if still failing, I would schedule a repair with a tv repair shop because it's dangerous to deal with internal portions of the tv as a consumer.
Thank you.
How can I fix my Vizio Tv?
Hell0, have you tried using a different HDMI input and HDMI cable? If you do and still have the same issue, it may be the eeprom on the main board going bad. Try doing a software update, some updates rewrite the eeprom and it may take care of this issue, otherwise the main board will need to be replaced. Thanks Techman 57
Why will my vizio E421VO not turn on?
Hi,
Please remove all extra devices (ie video game console, dvd platyer) and turn on your tv again. If not working, please attempt to change channels on your remote or remotes.
If still not working, please setup the tv like you did when you first bought it. Thank you.
Vizio tv
picture is fine but getting no sound
Hi Maria, indicate the model of your Vizio TV
See if it has a headphone output, if it has one, connect headphones and check for sound
If there is no sound, you may have a problem on the main board
Try going to the sound settings and settings and check that the speakers are enabled, if not, activate them, if they are activated, consult a specialized technical service
I hope you can solve the problem

Hola Maria, indica el modelo de tu TV Vizio
Fijate si tiene salida de auriculares, si la tiene, conecta unos auriculares y comprueba si hay sonido
Si no hay sonido, puedes tener un problema en la placa principal
Prueba ir a la configuracion y ajustes de sonido y comprueba que los altavoces esten habilitados, sino lo estan, activalos, si estan activados, consulta un servicio tecnico especializado
Espero puedas resolver el problema
Saludos Franco Dosil
