Coppell TV Repair LLC offers you an EXCHANGE SERVICE for your defecive LG Z-sustain module 6871QZH044C (or equivalent) as shown on the picture.

EXCHANGE SERVICE means you will pay for a serviced and tested module that is 100% compatible with yours. Upon verifying its functionality you can send your old dud and get credit towards your original payment.


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.


Typical failure symptoms of a failed ZSUS board are:

1) A very dark, blotchy display, slowly bleeding purple/red if left on the same scene for a few seconds; if you have that there is some 99% chance the cause is in the ZSUS board

2) Completely dark display. Sometimes, depending on the way the board has failed it may prevent showing any image on the display. This , of course, may be caused by bunch of other problems as well, so this alone is not a reliable indication yet a common one.

Check the temperature of the heat sinks on the board after leaving the TV for 5-10 minutes.

They should be warm, just as the ones on the YSUS board.

If they are not this increases the odds of this board being bad.

3) TV clicking on and then quickly back off, never setting on "turned on" state. This is possible if the ZSUS board has failed, shorted and has NOT blown the fuses on the YSUS board.

If disconnecting ZSUS from YSUS (there's a power cable that connects them) allows the TV to turn on then the ZSUS board is definitely bad.


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 you can return your old one to receive the advertised credit.

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 2-3 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).
