Replace e-prom on main board. Expert-tech.

Vizio Televison... | Answered Yesterday


Since the main fuse is being effected, it suggests that there is a major problem in the power supply section. I would be looking for a shorted rectifier diode. If you have any experience with electronics, you may be able to locate this problem. If hte set is still in warranty, return it for warranty service. If not, try loking for burned components etc.

Hello Anonymous, if you have replaced all the LEDs with LEDS of the same type and you have not missed any connection, it is very possible that you have a fault in the Power Supply board, it can happen
I send you a link to a video about your Vizio TV

Hola An?nimo, si has reemplazado la totalidad de los LEDs con LEDs del mismo tipo y no has errado ninguna conexi?n, es muy posible que tengas falla en la placa de Fuente de Alimentaci?n, puede pasar
Te env?o un link de un v?deo sobre tu TV Vizio

Hi Alon, as you say, it would be very possible that the main board is responsible for the malfunction of your Vizio TV
Because you say you have no image, no sound, assuming you turn it on knowing what input it is and there is some ymagen and sound, but the TV does not show you anything
If you were to have sound, there could be the T-Con board, since this does not affect the audio
I hope you can solve the problem
Greetings Franco Dosil

Hola Alon, por lo que comentas, seria muy posible que la placa principal sea la responsable del mal funcionamiento de tu TV Vizio
Porque dices que no tienes ni imagen, ni sonido, suponiendo que lo enciendes sabiendo en que entrada esta y que ah? hay alguna imagen y sonido, pero el TV, no te muestra nada
Si llegaras a tener sonido, ah? podr?a ser la placa T-Con, ya que esta no afecta el audio
Espero puedas resolver el problema
Saludos Franco Dosil

Looks like your screen backlights are not working. Check for faulty electrolytic capacitors on the power board and the backlight drive board. You may have to change the backlight drive board.

Blu Rays are more complicated from a information point of view--you most likely have either a dirty or bad (failing) optical pickup in the player--this always shows up first with blu rays.
