Coppell TV Repair LLC offers a REPAIR SERVICE for main board 3647-0302-0150 shown on the picture and used in Vizio M470NV smart LED TV.
REPAIR SERVICE means that you have to send us your malfunctioning board which we will attempt to repair, test and return back to you.
Note the board's PCB number should be 0171-2272-3237. The same PCB is also used in other TV models and has different finishout product number (ABCD-WXYZ-0150 number); boards with different product numbers are usually NOT compatible with each other.
If your board's PCB number is 0171-2272-3232 please use our listing for that board.
HOW DOES IT WORK
To have us examine and possibly repair your board(s) you need to send them or bring them to us.
Start the repair service request through the "Initiate service request" button on the page. Repeat customers are advised to log-in and new customers will have to fill-in a short form with contact information needed for communication and invoicing.
An email with shipping instructions is automatically sent once you submit the form to the email address you provide; it is also shown on your screen.
Following the instructions you package your board(s) and attach the first page of the shipping instructions so that we make a link between the boards and the service request when we receive your package.
You then send the board to us. You pay for the shipping to a carrier of your choice and nothing to us at this point.
Presently we do not charge in advance, but only after inspecting and possibly servicing the board(s) we receive.
The price shown is for evaluation, repair, test and return within USA of the boards listed in the title or explicitly named in the listing, provided they meet our requirements upon arrival (see related section).
Boards returned abroad tend to have higher shipping cost that will increase total cost of service beyond the amount shown.
Once we receive the package and open it we inspect the board(s) sent.
If the board(s) do not meet our criteria we communicate the problem with you and offer options, the first of them being returning the board(s) back for sole cost of return S&H. Other options may include surcharge for board restoration, board replacement, change of pricing or warranty terms etc.
We may not give any options and simply reject to service a board that was damaged beyond repair (see example here).
If the board(s) pass our criteria we conduct test to determine functionality.
If test passes OK and board(s) appear in working order we communicate that and offer options, among which returning the board(s) without change; we invoice a testing fee and return S&H charge.
We test all boards that are being sent and for every board we test we assess testing fee as described.
Boards that test out bad are analyzed and we attempt to repair them.
If we succeed we send a payment request for the amount specified in the listing.
If we fail to repair the board(s) we send you an email with details and usually only request that you pay for the return shipping and nothing else.
Please make sure your TV has the same board before proceeding with this service or contact us if yours is different to see if we offer repair service for it.
Below is a list of symptoms we have seen when this board goes bad. Some are different manifestations of the same failure, others are different failures altogether.
This list is not explicit. There sure are failure symptoms not included in it.
None of the listed manifestations points uniquely to the main board either, let alone guarantee that the main board is the only one at fault.
It is merely what we started with - a list of failure symptoms we have observed and which came to have originated from the main board.
- Front Vizio LED being solid yellow or just off and the TV not being responsive; (the later may also be due to a bad power supply board - check output voltages first!)
- Front LED blinking yellow for extensive period of time without setting down; TV may or may not respond to an attempt to the power off button; most of the time it does not and it just keeps blinking;
- TV starting up and showing the Vizio logo then either hanging there or restarting again
- Loss of sound or HDMI inputs
Typical turnaround time is 2-3 business days.
This is the time it takes for a package that was received to move up the queue and get opened.
Once we open the package we usually have about 1 hour to get the case resolved or we will likely end up losing money on it.
Sometimes, depending on situation, we may leave opened box and make another try on the next day.
Note that it is not guaranteed that the queue will take exactly 2 or 3 days to process. Sometimes - especially after long holodays - it can be larger and take longer.
We do our best, but we have no efficient means of managing the work load on demand.
REQUIREMENTS FOR THE BOARD(S) SENT IN FOR SERVICE
The board(s) we receive must be physically intact and must have not been tampered with or serviced before.
The advertised flat rate for repair service is only valid when the above conditions are met.
Exceptions are possible and often applied for minor repair attempts, but we reserve the sole right to judge if and when we would consider a repair minor.
If we receive board(s) that fails the above conditions we will contact the sender and usually offer two options: 1) returning the board(s) for the sole cost of the return shipping; or 2) continuing the repair service at a higher cost in case of success.
It is also possible, depending on the condition of the board, to eliminate the second possibility and just flat our reject having to service the board.
Subject to situation and availability we may also recommend replacement of the board, again at the higher than advertised price for repair.
In all cases you will have the option to receive your own board(s) back for the sole cost of the return shipping.
