LN32C530 service mode

[paulstef]

Hi guys, how do I get into service mode? I tried INFO MENU MUTE POWER ON and the 182 POWER ON option. Doesn't work.

The problem is the TV sometimes doesn't turn on, 24V will be turned on but not backlight command or PWM to inverter. The PSU is 100% working, DC voltages are nice and clean.

The net is full of people saying yeah change the little EEPROM on the mainboard or reset it. I understand how resetting it to default values from another memory location would work (via the service menu)
I don't understand how shorting the data or clock lines of the eeprom would erase its data??

Then some people say a new chip would need to be programed with an external flasher.
So far many contradicting and confusing information.

Can anybody enlighten me please?

Mute 1 8 2 power on

That doesn't work for this TV. I tried pressing them in different speeds, from normal to as fast as possible. Just turns on the TV (when it turns it on)

No. That's the first things I check of course. It's not that code for this TV.

There was a previous post in the forum you my find useful. Says he was able to purchase the EEprom quite cheaply directly from Samsung.

Yep, it wasn't clear though how to put the data in there. Is it stored somewhere in a PROM of a uC and then just loaded into the eeprom with default values? I don't know. Nowhere do I find clear information on what's going on.

PM the person and ask them.

Still not able to get into service mode BUT ... :-D

My TV was sometimes turning on, usually the first two times after an extended OFF period.
I went to the Samsung Firmware update website and updated the firmware from 1002 to 2006 and voila, problem solved!
