Show laocation of an eeprom on a main board - LG 32LG30 32 in. LCD HDTV

Let me get this right..you want to know where the EEPROM is located on the main board, then you want to short some pins but not sure what pins to short so the TV will magically reboot. You said something about "get it out of the boot loop"..The boot log is what you need for the TV to work, The ROM sends the various commands to the CPU telling it what to do to make the TV wake up and come on. For your set to work you need to REPLACE the IC, ld tell you where it's located at but I doubt you have the equipment to replace SMD components. Your best bet to fix the TV is replace the main board.

It is a common problem for this model, the problem is the defective EEPROM on the main board, to fix it you may find the correct EEPROM to replace it or change the whole main board.

Because you have a new power supply installed, then, In most of the case, the EEPROM on the main board is damaged, you may replace the EEPROM, or get a new main board.

ShopJimmy lists several models for $32-$40 (compare sticker numbers on the main board, but presently all but one are out of stock. They also sell a replacement EEPROM chip for the board for $15; evidently it is a common failure point. Replacement of the EEPROM requires the equipment and soldering skills to change an SO-8 surface mount integrated circuit.

Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Hello. The part number you need for the control panel/switch assembly is 74011491. The actual oven control unit is 74011494. The following list shows some(but not all) of the error codes you might encounter. I hope this helps you!
1c1c shorted key
1c2c membrane keyboard disconnected
1c4c board to board communication failure...." "
1c6c EEprom hardware fault..........................." "
1c7c control not calibrated............................... replace main board
1c8c eeprom crc error--user options..............." "
1c81 eeprom crc error--cook profile................." "
4d21 no cooling fan rotation
4d31 cooling fan on when de-energized
4d41 cooling fan overspeed
4d51 door switch circuit fault
In the service manual, there was no "warming drawer" error code listed in the code chart.

EEPROMs won't have no match. You should use the exact number. The loaded software cannot be changed; you know.

The EE error code stands for "EEprom Error" which means that the main control board EEprom program memory is defective.
Replace the main board.

FFF code - Control error, failed EEPROM

The main control operates a series of software commands, which control the various features and functions of the oven. Each function or operation has a numerical value assigned to it. The numerical values can be added up - this is called the check sum operation. Every time the system is powered up and after each clean cycle the system performs a check sum and compares the value to the value programmed into the software (stored in memory).

An EEPROM check sum error or FFF code occurs when the values differ. If this happens, replace the oven control board (also called clock or ERC).
