OFFER DESCRIPTION - PLEASE READ IN FULL!

Coppell TV Repair LLC offers you functional main board for Vizio M3D550KD LED TV as shown on the picture.

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.

Vizio uses various part numbers for this board in different batches of their TVs. The board out of your model may may have the same or different numbers from the one listed here - that is normal.

As long as your TV is M3D550KD this board will work in it.

Note the board is based on PCB 715G4404-M03-000-005K (alternatives may also exist).

Some vendors list this board, or rather that number, as compatible with M3D550KD and M3D550KDE. That is wrong!

The same PCB is used for base assembly for both models, but the parts they contain are different enough to make them INCOMPATIBLE!

This board will not work in M3D550KDE and vice versa!.

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:

  • Image supplied through HDMI ports is black and white;

  • TV responds to power on command, LED lights run at the front bezel, but the screen never lights up or lights up, but with no image;

  • TV starts up and LG splash screen shows up, but freezes there;

  • TV comes up and has image, but the image or audio is garbled;

  • Loss of HDMI ports or loss of audio.

WARRANTY AND RETURNS

We offer 30 days limited warranty covering parts and labor. If board needs to be returned customer is responsible for return S&H costs and CTVR is responsible for repairing, replacing or refunding the customer, subject to availability and preference.

Return of functional boards is subject to return and restocking fee. We prove board's functionality with a video, so if you intend to return the board make sure to sign it with a Sharpe so you can be sure it will be that same board we show you functional (if it is, of course).

Total withholding amount for returned functional boards is determined by adding the forward shipping cost, the eBay transaction fees and a $10 fee for testing the board prior to slating it for sale again.

Warranty is voided for boards with traces of tampering, damages caused by poor packaging or other physical damages that are not covered by the customer's carrier.
 
CONDITIONS FOR BUYING BACK YOUR OLD DUD

Once you receive the board and fix your TV you can return the old malfunctioning board to us to receive the advertised credit.

It is usually given as a credit towards the original payment, subject to the below conditions:


1)  Your board must be sent within 14 days of delivery of our board, both per carriers' records. Be sure to keep your tracking number when you send the board to here.

2)  Your board must arrive physically intact (not broken, not cracked, no deep cuts, no ripped off components, no moisture damage), with no missing or physically broken components or traces of tampering, all with possible exclusion of damage resulting from electronic failure such as burned components.

Violating the requirements would result in us contacting you and asking if you want the board back for the cost of the return shipping alone or a trade-in value we'll determine based on the board's condition.

We ask that along with your board you return the piece of paper that you will receive along with the board that we will send.

Please keep the tracking number for the return you will be sending to us and allow up to 5 business days after its arrival to our shop before you see your CORE refund initiated or get otherwise contacted by us.
