    LN32C530 service mode

    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?

          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!

                                          So i got this tv from my neighbor, when it wasn't working right for him,, he purchased another tv and gave his old to me.
                                          the color is all outa wack, like the settings have been corupted,
                                          I've already done a firmware search using the wifi connection update from the tv and it didn't find any new update so it's got the most recent version.

                                          so
                                          The issue is i can't get into service mode or factory mode, tried resetiing it from user mode and it didn't change anything.
                                          when i bring up the menu and type the pass codes to access either mode the menu disappears...

                                          Hi,

                                          I have this board, where I have exchanged the LGA1151 socket. During testing I discovered, that the large PCIEX16 slot won't by no force work in x16 mode, but keeps to work in x8 mode only.
                                          I tested this with GPU-Z, also with Render Test (but tried also Furmark and Heaven Benchmark - no effect).
                                          Tested on Core i5-9600K as well as on an Pentium G5420 and MSI NVIDIA GTX1070 and 2 other cards, including RTX3060Ti.
                                          Board architecture definitely allows x16 mode, as all 16 PCIe lanes are present between CPU and main GPU slot (nearest to CPU).
