A functional Vizio M3D460SR LED TV main board will let you repair your failed TV and send the old board for credit.

Out of stock

( alternatives are available – see below )

Coppell TV Repair LLC offers functional replacement for the main board for Vizio M3D460SR as illustrated on the picture, except the picture may have the board for M3D550KDE - see notes below.

Vizio uses different part numbers for this board, which include, but are likely not limited to TXBCB2K01204, TXBCB2K01205, 756TXBCB2K012 and TXBCB2K0120007.

If your TV is M3D460SR this board is for it regardless of the number on your board.

Note the board is based on PCB 715G4404-M01-000-005K or 715G4404-M01-000-005F (or other we don't know of), which many vendors incorrectly list under different models, e.g. M3D550SR and M3D460SR.

Even though the PCB upon which the final product is the same for different models, the components on it are not and, at least in this case, the main boards for M3D550SR and M3D460SR are not compatible with each other!

On another note, some versions of the board (we've seen it in TXBCB2K0120007, but there may be others) come without the circuitry and connector for an extra bass speaker in the TV. See attacheed pictures. We list all boards as equal here, which means that you may receive a board without the functionality for the 3rd speaker even if your TV has it or you may receive board with that functionality even if your TV may not have one installed.


You are purchasing a functional module that is same or 100% compatible with the one advertised in the subject of this listing.

Upon receiving and installing the module in your set you have the option to return your old malfunctioning dud and receive credit towards the purchase price shown here, subject to the below listed conditions.

The board you will receive can be brand new, used or, most commonly, a board serviced by us, Coppell TV Repair LLC.

Unless it is brand new (which is rare for the modules we offer as we specialize in servicing hard to find or expensive TV boards) it is guaranteed the board will be tested by our staff and there will be a label on it attesting to it.

Before placing an order please ensure that this is indeed the board in your set by comparing the number on it.


All packages we receive are placed in a FIFO processing queue.

It takes 2-5 business days for a package to make its way from the back to the front of the queue.

Once picked up for processing, we make money if we manage to fix the board(s) inside for between 30 and 60 minutes.

Of coruse that isn't always possible, not to mention sometimes there is more than one board in a package.

Add to it that we can't know how many packages we will receive at any given day, how many boards will each contain and how bad the damage on them could be.

Please do not call us a mere few days after you sent your package to inquiry about the status of your service...we just do not have the resources to be giving the same answer to everyone and it only slows us down!

Look at the tracking number, see when it was delivered, give it at leat 2-3 business days (preferably four) and if you have not heard anything from us then contact us saying the package was delivered on this and that date and we'll go look for it.

It's in everyone's interest that we work as fast as possible and interrupting technicians (who answer the phones) to make them go search for package in the queue only to tell you it's there doesn't help anyone.


Unless otherwise explicitly stated elsewhere in the listing the boards we sell come with a standard 90 days warranty.

Customer is responsible for return shipping and Coppell TV Repair LLC is responsible for shipping back to customer. Returned boards subject to exchange, service or refund, subject to availability and agreement by Coppell TV Repair LLC and customer.

Returned boards must carry the Coppell TV Repair LLC identification stamp or label and must not have been damaged, modified or otherwise tampered with in order for warranty coverage to remain in force.

Boards returned with request for refund / order cancellation will be subject to restocking fee covering forward shipping cost, transaction cost and $10 fee for the board testing needed prior to slating it for sale again.


Upon receiving and installing the purchased module buyers can return the old one to receive the advertised credit. Returns are optional and buyer's responsibility; it is usually OK to reuse the original packaging unless it was visibly damaged beyond normal use (in which case we usually hear from buyers anyway).

The credit will normally be issued as a partial refund towards your original payment; when this is impossible or inapplicable we may use other forms of payment such as PayPal or check.

It takes 2-5 business days after the delivery of your board to us for it to be processed and the refund issued.

In order to receive the full advertised credit the returned dud must meet all of the following conditions:

1) It must be sent back within 14 calendar days of the delivery of the module you purchased from us, both per carriers' records. Make sure you keep your tracking number, you may need it!

2) The board must arrive in good physical condition allowing subsequent electrical repair and reuse of the board. Sometimes when components fail and burn they also leave burn marks on the board. Most of the time such traces are not affecting the ability to restore the board's functionality, but in some extreme cases this may be a problem.

3) The board must not have missing or replaced components or have otherwise been tampered with.

Exceptions vary from all 3 listed conditions, but we reserve the right to be the judge on whether your board qualifies for an exception.

If a board arrives that does not meet the above conditions and we do not consider it appropriate for extension we will contact you and offer you to get it back for the sole cost of the return shipping and/or offer you a trade-in price we consider reflecting its condition.

The returned module must arrive in good physical condition and without previous traces of repairs or tampering in order to qualify for the full advertised credit.

Modules that do not meet those criteria will be subjected to partial refund or no refund at all (depending on their condition and trade-in value).
