Kit ID: CTVRK-PB-NO-0099

Kit contents: The EEPROM IC US4 found on Vizio main board 3642-1472-0150 / 0171-2271-4355 .

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.
