Coppell TV Repair LLC offers a REPAIR SERVICE for main board 62882801 / EAX66105904 shown on the picture and used in LG 31MU97-B 4K LED monitor.

REPAIR SERVICE means that you have to send us your malfunctioning board which we will attempt to repair, test and return back to you.

The board's PCB number is EAX66105904 and the same PCB is also used in other models; at this point we can only test visual output for LG 31MU97-B.

Your biggest issue will likely have sending the board for repair will be opening the monitor. We use two or three plastic cards (debit or credit cards, hotel door key cards etc.) which we stuck between the back cover and the TV frame and move them around. Be extra careful, the LCD panel is fairly sensitive and easy to crack and you may not even notice you did!

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.

SERVICE TIME
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.

WARRANTY CONDITIONS

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.

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 previpusly serviced. Exceptions my be made for boards that carry our own service label and stamp and do not have signs of tampering.

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.

Board removal hints

One way to open the LG 31MU97-B and BC models is by using old plastic cards like credit cards or rewards cards etc.

After detaching the base with the screws from the back with regular screw driver, you lay the monitor on a flat surface with its face down and carefully insert a plastic card in the middle of either of the two longer sides (top or bottom in landscape orientation).

You will pry a bit to get the card inserted and once you do you will push the card down or up to maintain a good angle, which would allow you to pull it sideways while pushing the locking clips apart from each other; force *is* required in this operation and a clip or two may get damaged, but that is not too common and hardly ever fatal.

The boards are far enough from the edge and it's hard to do additional damage unless you drop the monitor or press too hard with fingers against the LCD.
