In this case you need to write the eeprom or the nand flash memory again with a programmer or service interface. You can try with a blank eeprom first.

Try updating the firmware by USB.
You should be able to do this without the remote.

Either way it's important to update the firmware on this TV, without the most recent update installed the TV breaks down fairly quickly.

Re: samsung tv problem

Thank you for your reply. How do I go about programming the eeprom or flashing it. Is there any tuts I can follow please. And as for updating the TV it keeps failing hence the reason why I went into the service menu.

You need a programmer to read/save/erase the eeprom IC901(24C512) first. You can try to reset the tv set with SZW1201 that is not mounted.
