Element 40LE45S main board E090402/LTDN40W07US repair kit / EEPROM N15

Coppell TV Repair LLC offers replacement for the memory IC N15 used in Element 40LE45S LED TV.

Coppell TV Repair LLC offers the EEPROM IC containing the firmware for Element 40LE45S main board E090402 shown on the picture.

The board has a number of identifying labels among which "LTDN40W07US" (usually followed by a digit in brackets, e.g. "LTDN40W07US(1)", "120639", "120640", "E090402" (found in the middle of a larger identification number).

At time of creating this listing we are not certain which of those is a unique board identifier, if any, but we are sure that the same PCB is also used, with minor differences, in other TVs such as certain Proscan models.

It is important that you understand this EEPROM is for use with ELEMENT 40LE45S only!

Please read carefully the below information and specifically the warranty conditions section.

Do not hesitate to ask if you have questions and good luck with your TV repairs!

Kit ID: CTVRK-PB-NO-0098

Kit contents: The EEPROM IC N15 found on Element main board E90402 / LTDN40W07US / 120640 .
The IC you will receive may be from a different manufacturer from the one on your board, but it will be fully compatible and containging the proper firmware.

Difficulty level: Medium to advanced. The memory IC requires soldering by experienced technician with quality soldering tool.

Generic firmware failure symptoms: As with most if not all other cases for failed firmware there is no simple and definite way to test confirm the problem is there, let alone only there. Below are some symptoms we've seen caused by a defective memory IC however you should bear in mind other failures may lead to the same symptoms.

  • A totally dead TV; this is actually model specific. Some older TVs have separate standby processor and most newer models use a single processor for standby and full operation mode. A bad firmware (or bad clock generator, for example, or bad solder joint on the processor) could leave the entire board dead.
  • Some TVs may be blinking a number of time and pausing or just continuously blinking , in either case not responding to any button. Some may respond to the power on only to start the blinking procedure again.

Repair service offered: Yes. If you consider the job too difficult or like to use the benefits of the warranty our repair services carry (and which our repair kits do not) search at our site for a risk free repair service for Element 40LE45S main board.

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.

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.

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.
