Tom,
I recently had a power surge at my house due to lightning. It knocked out my Vizio TV. The TV was under a buyer's protection plan, and last Thursday, I watched, and even helped, the repairman fix the TV in my house. It was incredibly simple! We removed the back (a lot of screws). Inside were two circuit boards. We replaced the smaller one first, which was the power board. The TV would then come on, but there was no picture. We then replaced the larger board (I don't remember what it was called), and everything was fine. Both boards were very,very,VERY simple to replace (plug and play). It actually took longer to remove the screws, to get the back off, than it did to replace the two boards. The repairman told me that modern TVs are simple and any problem is almost always one of these two boards. He told me that replacing both of these boards is like having a new TV. I then tried to find a good place to buy these circuit boards in case of future problems. I could not find a good place to buy these boards. If you decide to make the repair yourself, and find a good place to purchase these circuit boards, I would appreciate the information. Hope this helps.
