Coppell TV Repair LLC offers the EEPROM IC containing the firmware for LG 31MU97-B main board 62882801 / 31MU97/LM41C / EAX66105904.
The EAX number above is the PCB number, which is not unique as one PCB can be used in different models with different features and even used in by different manufacturers, so it should NOT be used for reference in the context of searching for a proper EEPROM replacement!
You should instead use the appliance monitor (31MU97-B) and/or the unique product number for the main board for this monitor -62882801 in this case.
Simply put, this EEPROM is ONLY guaranteed to work with LG 31MU97-B only and not with any other models even if they have the same board inside!
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 repairs!
Kit ID: CTVRK-PB-NO-0134
Kit contents: The EEPROM IC205 found on LG main board 62882801 in LG 31MU97-B (back of the board) .
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: Easy to medium. 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.
