Le32c450 in image or backlight suspected mainboard

[noledud]

Hi all got this samsung with no backlight or image, I believe the set is on as it flashes during startup then responds to remote signals

Now when I unplug the main board the back lights work so they and power are ok, had a set like this befor and had to replace the main due to suspected EPROM corruption

Now I wanted to try a factory reset but obv very hard with no image

Can some one go into engineers menu on a c series ( the newer type menus I believe ) and count the direction and number of presses to do a reset ?

Worth a go but I don't have another samsung of the same series here

Thanks all

Re: Le32c450 in image or backlight suspected mainboard

ok all these are what iv tried

heated main board = no change

Re set eeprom ( IC502 ) = No change

Replaced eeprom IC502 = no change

Not sure what else to try iv read there is another eeprom ( come pre programmed )

found here http://www.ohmsupplies.co.uk/epages/...on=ViewProduct

however the details are

SAMSUNG LE32C450 EEPROM
CCT REF: IC402
BOARD NUMBER: BN41-01331 / BN94-02616
SPI EEPROM
FAULT SYMPTOM. DEAD / STUCK IN STAND BY.
PLEASE SEARCH FROM BOARD NUMBER AND NOT MODEL NUMBER

I can only find IC 501 and IC 502 but my main is a differnt mine is BN41-01479a BN94-02699T

is it worth trying that eeprom ?
