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. Those include, but are likely not limited to 756TXCCB02K011 and TXCCB02K0110003 – numbers that can be found on white stickers, NOT PRINTED ON THE PCB! If your TV is M3D470KD this board is for it regardless of whether the above numbers can be found. Note the board is based on PCB 715G4404-M04-000-005K (alternatives may also exist), which, depending on the components that are placed on it, is also used for assemblies for other models, such as M3D470KDE or M3D550KD, Those final assemblies ARE NOT COMPATIBLE WITH EACH OTHER! THIS BOARD WILL NOT WORK IN M3D470KDE or M3D550KD or M3D550KDE AND VICE VERSA EVEN THOUGH THEY MAY ALL HAVE “715G4404-M04-000-005K” PRINTED ON THE PCB! COMMON FAILURE PROBLEMS 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.
