Coppell TV Repair LLC offers you main board 3647-0312-0150 as shown on the picture and used in Vizio XVT473SV LED TV.

The board was serviced and tested by Coppell TV Repair LLC.

Upon receiving and installing the board to satisfactory results you can return your old dud subject to the terms and conditions specified in a section below.

If you look closer at the picture you will find two particular identification numbers at the top left corner (going vertically towards the top): a large "0171-2272-3237" printed on the board itself and a smaller "3647-0312-0150" printed on a white label just above the 0171 number.

The "3647-..." number (suffix does not matter) is the unique identification of the revision of the board that contains the particular set of components that makes it work on the Vizio XVT473SV model.

Other components would be used in other versions of the board to be used on other models. They would have the same large "0171" number since they use the same PCB, but a different 36XX-ABCD-WXYZ number.

Differences may be small or big, but as a rule of thumb you want to replace a board in your TV with the same or knowingly compatible one or you risk malfunctioning and even damage ( we ourselves learned that the usual expensive way).

Before placing an order you must open your TV and verify that this is the board you need. It should be used ONLY on Vizio XVT473SV models and, ideally, only as a replacement to a board with the same unique identification number.

Coppell TV Repair LLC will withhold return shipping costs, eBay fees and testing/restocking fees for all boards returned due to improper ordering.

Common failure symptoms

While there can clearly be a large number of failures and failure symptoms that probably can't all be listed, here are the most common ones we've seen this board cause that we've seen:

• Totally dead TV ; this can be caused by a bad power supply as well, but at least for the XVT473SV model we've seen the main board being bad more often than the power supply board;
  
  
• The front LED indicator blinking endlessly, but the TV never starting up;
  
  
• The front LED blinking for a while and then stopping just as it should, but then the TV hangs without doing anything;
  
  
• Loss of HDMI ports or loss of audio.
