SAMSUNG LE23R81BH MAIN MENU BLOCKED

<< < (2/3) > >>

 :c017: Sparky i ve tried everything in the service menu, i even replaced ic 1803 eeprom 24256 with a new one
and still you cannot call up the main menu.
The set is 80 pics i needed to fix. :96:  :sign0085:

Perhaps you can try this:

Blocking the SDA or SCL lines on the eeprom will disable communication by the chip.
Connect eeprom VCC to SDA line. It wont hurt it as the SDA normally idles at VCC.
Power the tv on for 20 seconds. It will try to read (the wrong) settings and start with defaults.
Then releasing the SDA line and shutting the tv off will update eeprom settings with null values
that will allow the tv to boot with.

Only do this if you have the service mode option values - usually given in the service manual.

Hi downunder, i ve done that too and no result, it seems the eeprom is not communicating with the Cpu directly because after connecting pin 5 or 6 of the eeprom to Gnd, and switch tv on for 20 sec. and you released the pins from Gnd the set ll not restart itself, it ll come on as if nothing has happen to the eeprom.
still i need         :sign0085:

Well, you got me there, jagbo. Not sure that these have a Hotel Mode. There is a "Hotel" option in the

Option Table in the Service Menu, but I think it's dormant.....I've never been able to activate or deactivate

it. Seems to be more for decoration than use.        Bruce

 :c017: anyway , it might be that this model could not be hacked to get the user menu , but am still sure there might be another  way  to resolve it so guys  :96:
