UE37C5100 don't turn on: standby led blink 6 times

[lepak06]

Hello

I've an Samsung LED UE3c5100

The TV don't turn on, the standby led blink 6 times .

I checked the power supply board is OK . All voltage
I checked all the voltage on the main board ( with service manual) are OK.

I think it's the EEPROM is corrupt. What is your idea?
I didn't find the firmware for this TV.
And with schematics i found there a lot of EEPROM's on this TV. Which the EEPROM for the powering ?

Thx

Can we see pictures of the whole back side of the TV showing all the boards?
How about the control signal Voltages, what do you get?
Power supply board is BN44-?????

The power suuply board bn44-00351B
The power supply is good . All voltage are OK. I made a shunt for the backlight ON/OFF and the backlight is ok.

I found the all voltage that write in service manual for checking in "no power" section.

I extracted eeprom files:

IC501 read at 24C256
IC502 Read at 24C02
IC901 - ATMLH038 (i tried to read at 24c01 and 24c02)

Can you say me if my eeprom dump are ok without faulty.

I tried to flash with dump from UE32c5100 , without changing only with IC502 with the new dump of ue32c5100 the when i plug the AC cable the standby led don't blink only after press on power button the led blink 6 times and no turning on.

My properly working samsung lcd tv has a solid standby light when tv is off, when I turn it on it blinks 4 times tv comes on standby light goes off.

Before, when the television worked, after pressing the button puwer, the led flashes 6 times and we hear samsung jingle and telly turn on. Now after flashing 6 times the led remains off and no picture and no sound then we can not turn on or off any reaction

That's a tough one, you might be on the right track, wonder if it could be a faulty led strip or led short keeping it from coming on.

The led strip was tested ok.

I need eeprom dump to check this way
