Description content of EEPROM: Before repair TV not stored some settings (eg. set of initial music, power saving (brightness of CCFL)) and other settings. I backup these content and try write of content these eeprom from LE32A656, but content from A656 have a problem with some settings, so rewrite backup. After I enter to service menu (TV off in stby mode - red led light) push in remote key: INFO - MENU - MUTE and POWER ON. I shoot settings and execute menu item "FACTORY RESET" After rest factory, all settings work fine and check values via photos.
Включался с третьей попытки,потом с пятой,да и вовсе перестал.Индикатор дежурного режима горит-на ПДУ и кнопки на ТВ не реагирует.Слил прошивку-перезаписал на чистую spi flash 25Q64 -аппарат ожил.
