Yes you can, but in most cases cost to replace the panel could cost as much as a new set. If you decide to replace the panel, you will need to get your LCD panel model # before ordering a replacement. You will have to open your set. There should be a white sticker on the back of your panel stating the model #.

Hello
The T'con board [Timing Control Board] of your TV has damaged.
The board will look like this. Will be in a shelded case which you can open it by unscrewing it, and can take out the board. Replacing it is a semi-skilled job indeed. You can buy this board from most of the electronic spare part shops at your town, or from the authorised service center for Vizio at your town. Never use a refurbished bord in place, as it may make damage to other boards. If you want its service manual, not user manual, you have to buy one amoung my pro service from Fixya. I can't send it to you directly as it is against our expert terms. If you wish to get the service manaul, get me either by Fixya Pro services, or just type my nickname "gopakumarg43" in Google search box; where you can see my services, and get me. OK.

Check for bad capacitors in power supply, check voltages coming out of the power supply, if voltages are good, bad main board.. Vizio's are notorious for bad main boards.
