hi

this is my first post and sorry if this is the wrong thread.

my model is LE40A552P3R and it is hanged at firmware upgrade process which is from samsung website. i removed the USB stick and does not switch on now

info-menu-mute-power option and 12 seconds exit button does not work for me. stucked

any idea ? do you suggest to reset the eeprom or any other idea ?

thanks

build exlink cable and try to check what`s the output on debug. If lucky, you will get access to uboot. If not lucky, then - mainboard replacement. (it`s time to buy new tv?)

thanks for the info, replaced mb. costed 50 $. will never touch to the fw again
