After replacing the main board, in most cases a software update might be necessary for proper working. Here you have replaced both power supply and main board I assumes. If so, it is a must to update it. If you wish to get more details about the software update proceedings, check this link. Screen shot illustrations are give in detail.

Tv completeley went out , first the picture then sound. took it to a tv repair shop and the power board checks out ok can not find the problem so he is not chargeing me wants me to pick it up


Hi,
On the Vizio LCD TVs there are only two boards: Main board and power board.
There is also the screen. If they checked the power board then all that is left is the main board or screen. If the power light stills changes color when ther power button is pressed you may have a bad screen (costs more than the TV if even available)
If no lights come on the main board can be tried to see if it fixes it, the main board will cost $200-$400.
These screens go bad so I'll bet the shop did not want to try the main board as they can not return it after buying it
Buy a new set is my advice
Hope this helps
thanks

I have a X2Gen 42" LCD (MV42P) that has no picture


if there is no dispay in the screen atall then it has to be the screen or the unit controlling the screen which can be in the same unit as the screen sometimes also if you have replaced the power supply the main board and the controll board then there is either something wrong when fitting them or one of the units are faulty but i am thinking the screen mate i cant explain the sound it could be caused by the fact there is nothing to display meaning there is no picture being send and no sound,,,,


if you have any light atall in the screen when the tv is turned on this cant be the problem

it sounds like the input device is not inputing anything ie the hdmi or scart is not sending through and the tv and dtv are not sending this would explain why no screen and no sound because there is no sound or picture being send through and because the unit is broken there is not even any menus

Sharp Aquos HD black screen. Sound but no picture. Remote will turn TV on, but will not change inputs or do anything else. Happened suddenly.


Look at the venting grills to see if you can see any white lights inside, if there is no light, the backlight inverter board may have gone out or the main power supply for the inverter board is not working. If you do see the lights then the problem can be in the main controller board.

Olevia 42" LT42HVi has sound but picture had gone blank.


You do have sound, but no picture.
I believe the power supply and main board is ok, because you can hear the audio.

Most of the majority of these problems that have no picture is the back light inverter. That's what supplies power to the screen. I would look into that as the source of the problem.
