CPU IC1102 SETD-10
Repair description: BAD IC204 (AOZXXXX) DC-DC from 5V STBY (A5V) to 1.1V STBY (SB1.1V - VCORE for IC1102) I use external DC-DC adjustable converter - see picture and instead trimer i use parallel resistors connection 3k3,100k,100k (3.1kOhm)
Bad firmware in IC402 I reflash via firmware from Ерлан.
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.

После пришлось заменить SPI Flash на EN25T80(другой не было) так-как тело перестало включаться. Включение происходило с вставленной USB Flash на которую был извлечен файл обновления.

PWR supply board BN44-00209A PSFL171501A - problematic stby pwm IC FSDM365R is thermal stut down (bad cooling and small power reserve) after 10 minutes after TV turn on, just bad design, because this stby supply powered after TV turn on also main 5.3V power line.
Firmware I personally downloaded from good functional TV LE32M87BD and I reflash all flashROMs and config EEproms in motherboard to other same TV type. Bad TV before repair has symptoms: - Red LED blinking and not starting backlight and no screen - only restarts repeatedly to infinity (power on, main power supply section turn on, led blinking, main power supply section turn off, restart and still again).
Bad TV has bad caps in power supply board and bad low drop voltage regulator 3.3V in SUB LVDS BOARD TULIP32 BN41-00895B.
SAMSUNG LED-32E58S здесь на сайте есть такая же модель http://remont-aud.net/dump/lcd_pdp_tv/samsung/led_32e58s/241-1-0-11686но она у мена идёт негативом
