3407F 100 bit shift register IC replacement for plasma TV buffer boards - new, unused

Get a replacement for a failed 3407F shift register IC used in some 50'' plasma TV buffer boards, but make sure you read the listing first!

Coppell TV Repair LLC offers you a brand new replacemen for plasma output shift register IC 3407F used in various plasma Y driver buffer boards.

Those are used in various 50'' plasma TV buffers, such as Samsung HP-T5044, HP-T5054, LG 50PG20-UA and others.

Note there are a number of equivalent substitutes made by various companies such as Panasonic, TI, Infineon and others, which we have all seen used by OEMs in the same parts.

The component you will receive may or may not be 3407F, but it is guaranteed to be 100% functional equivalent from a brand manufacturer.

We use those ICs in our daily repairs and there is a number of videos in our YouTube channel where you can see us proving functionality of serviced buffer boards and disscussing the failures and the repairs.

There are no "counterfit" ICs that we are aware of. The worst that we have seen - in regards to such ICs - is when Asian vendors try to pass used and washed ICs as brand new ones. If properly done, this is hard to identify which is why it is important to have a great relation with a few reliable vendors, which is what we do.


Normally ships within 1 business day. Unexpected delays may occur, but if we can't ship within 3 business days we will contact you or/and cancel the order.

We try to ship every business day M-F and, for USPS shipments, Saturday as well.

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, 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.


Coppell TV Repair LLC does not guarantee that this product is all that is needed to resolve the problems with your TV.

Most of the repair kits we offer are based on first hand experience servicing boards at our repair facility. 

Over time they may get expanded with our own experience or information from manufacturer service bulletins, customer feedback etc.

Yet failure can be unique and there can not be guarantee that what has worked one, ten or even hundred times will also work the next one.

Just as important, every repair involves about equal portion of quality of parts and quality of worksmanship and as we have no control over the worksmanship quality unless we are the ones performing it we would be unwise to provide warranty of the products utilized by that worksmanship.

As such, no warranty is offered on this product once the components in it are soldered on a board.

If you would like warranty please see if a REPAIR SERVICE is offered instead of a kit. Unless otherwise noted all our repair services do come with a standard warranty.
