Kit ID: CTVRK-PB-NO-0089
Kit contents: The EEPROM / flash memory IC found on Toshiba main board 75025138 used in Toshiba 40S51U LED TV.
Difficulty level: Medum to advanced. The memory IC requires soldering by experienced technician with quality soldering tool.
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. Such is the case of the Toshiba 40S51U.
- Toshiba 40S51U may be blinking 3 times and stop or just keep blinking the 3 times over and over, in either case not responding to any button other than possibly power.
- In at least one case we've seen the sound being affected by the firmware - it was very quiet and there were occasional random noise in it. That particular issue is also resolvable with firmware update from Toshiba.
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 Toshiba 40S51U 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.
Coppell TV Repair LLC is not aware of an easy and reliable way available to end users that will allow them to identify beyond doubt a defective or corrupt memory IC.
We describe failure symptoms that we have seen when the firmware IC was corrupted, but those symptoms do not directly map to defective memory IC and the other way around - an EEPROM can be deffective or corrupt and there may be other symptoms that are not listed here.
It is up to the buyer's technical skills, equipment and willingness to assume the risk for the outcome of their repair service effort when purchasing and using this product!
By placing an order customers agree to assume that risk and hold Coppell TV Repair LLC free of accusations and charges related to the outcome of their repair except in regards to the correct presentation of the product and its delivery.
Coppell TV Repair LLC guarantees that the offered memory is new, tested and functional to the best of company's knowledge.
To anyone who does not have the skill and equipment needed to diagnose the IC in their own board we strongly recommend using a purchase/trade-in or a repair service, which we may (and should) be offering for the main board.
