Serviced buffer boards are usually used when brand new boards are either not available or offensively expensive. See the below section for more details of pros and cons of using serviced boards.

If we are out of stock on this item chances are we may be offering a repair service where you can send your board and we may service, test and return it to you. If you do not see such a listing please contact us to request about such a possiblity!

HOW DOES IT WORK

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.

FAILURE SYMPTOMS

A buffer board can fail in several different ways (probably even more than we have seen), but based on experience probably the most popular failure symptom of the TV would be periodic clicking from the power supply and the TV never actually starting up.

A much better indication that a buffer has failed is establishing bi-directional (as opposed to uni-directional) and usually low, in terms of tens or at most hundreds of Ohms, resistance on the contact points of the large red capacitors found on the buffer board.

SHIPPING AND HANDING

Ships within 1 business day.

We ship every business day M-F.

Items under 14 oz are normally shipped with USPS First Class mail unless other option was available and chosen during checkout.

Packages of 1 lb. and above are shipped USPS Priority, FedEx Ground/Home or FedEx SmartPost, subject to our decision.

ATTENTION INTERNATIONAL CUSTOMERS: If your order is accepted by our store and your address is outside United States you may not be able to track package delivery progress once it leaves the country. The United States Postal Service (USPS) does not provide tracking information to some countries unless the shipment is the most expensive Express type, which is usually too expensive to justify using. You can accept that condition and strip Coppell TV Repair LLC of responsibility to the delivery status of your package provided we show it was shipped and processed by a courier in a timely manner. Or you can contact us prior to ordering and inquiry for delivery confirmation shipping method, which, again, usually costs an arm and a leg compared to the simple USPS First Class shipping.

WARRANTY CONDITIONS

We offer no warranty and return conditoions for serviced buffer boards other than for missing or thick horizontal lines resulting from bad (missing or joined) solder joint on the ICs we've replaced.

We can produce and show a video proving the board we will be sending is functional, but once it leaves our office we take no responsibility of its life span and any defects beyond the previously mentioned ones.

See the SERVICED BUFFER BOARDS section for details.

USING SERVICED VERSUS NEW PLASMA TV BUFFER BOARDS

There are pros and cons to using serviced versus new parts.

Common sense suggests that it's always better to use the new, however that is not always possible and we believe it is not even always valid; sometimes a service may account for and correct a known design or manufacturing flaw - add a voltage or current limitation component to a circuit, add a ventilation device, introduce new software containing bug fixes etc.

In regards to plasma TV buffer boards the common sense is usually correct and we recommend using brand new over serviced whenever possible.

One key reason for that is that what wears in plasma TV buffer boards - if anything - is the shift register ICs on the buffer. Those are the square evenly spaced blocks - usually 4, 6 or 8 per board - which corners are covered with silicone or coating.

If and when those are keen to expedited aging and failing the logic says that since there are a number of them and usually only one or a few fail at the same time (very rarely all at once) then unless all are replaced at the same time with new ones, the original remaining are logically expected to have shorter life than this of a new buffer board.

Manual repair, on the other hand, is such that if more than 2 ICs have to be manually replaced it is usually not economically viable to make a repair in the first place.

The result of all that is that a serviced buffer board usually has only 1 or 2 ICs replaced and is normally expected a shorter life than this of a brand new board; maybe just as importantly, if a top buffer board has failed (and the bottom has not) and only the top buffer is expected to be replaced (new or serviced), then by the same logic the bottom buffer board should also be replaced or it decreases the expected time to failure of the whole assembly as well.

Which is not to say that serviced buffers will have unreasonably short life time.

In fact, we have no way of telling how much a serviced board will work before failing again, but we've been servicing and selling buffers for over 5 years now and we can say that it can span anywhere between immediate failure (in which case the problem is usually NOT the buffer board) and several years.

From where we stand, we recommend using new buffer boards whenever possible and practically meaningful.

When new buffers aren't available or are too expensive you can give a serviced one a shot to get a few more years out of your TV at a reasonable price. We wouldn't be offering them if they fail a lot, but that said we have no way of predicting when a serviced buffer will fail - hence the decreased or even eliminated warranty on them.

From where we stand, we believe serviced buffer boards should be used when brand new alternative is


REQUIREMENTS FOR RECEIVING CREDIT FOR YOUR OLD MODULE

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).
