      Maybe it's not an EEEPROM problem. Can you post picture of your circuit boards and how they are interconnected. What voltage readings have you taken/

          Hi Rawan,
          Could you add the EEPROM data to the Forums EEPROM data list so that it could help others.
          Many thanks

                  Can you post the power supply connection to the mainboard. It may show what voltages should be on the pins.

                          Hello!
                          I have this very weird problem, I got this rx580 nitro saphire and the fans don't even spin but the saphire logo is lit.
                          All voltage rails are present except for VCORE at the coils, then I started checking NCP81022 and it has voltage but vdd pwrgd is missing, enable EN is missing it shows 2.5ohm, everything seems fine, i tried checking the back of the card, to see where the enable pin goes, i dont have a schematic so i started touching randomly until i measured a resistor on the back and the fans started spinning, now I was amazed like what is wrong here? So I thought it's a...

                          Samsung UE32J5373AS Weird LED Problem
                          by sorrowfulfloyd
                          Hi all, first time seeing a LED problem this weird so I wanted to discuss with y'all before handing back this TV to my costumer.

                          This TV came to my shop with no picture but sound present. So I thought ok this must be a LED problem and I shine a light with my phone's torch amd and yup I see the image. So I disassemble it and before changing the LEDs I check the motherboard voltages (this unit works with an external 16V DC brick) and I see 54 volts at the input pin of LED strip, considering this TV has 2 strips of 7 LEDs which at 3~ volts it must be equal to like 42 volts. I remove...

                          Problem with LG Plasma 60PM6700 - Random power downs
                          by theone111
                          I have an LG Plasma TV 60PM6700 for the past ~12 years.

                          In the last ~3-4 months I have been having some issues.
                          1. Problem: It started with random picture disappearing (sound still worked).
                            Frequency: Happened about once a week.
                            Solution: Had to turn off TV wait a few seconds before turning it on again.
                          2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
                            Frequency: Happened about once a week.
                            Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.
                          3. Problem: TV shuts down

                          Macbook M1 A2337 EMC 3598 weird battery charging problem
                          by brockauly
                          Hi guys,

                          If I unplugged the battery and the charger, then plug the battery then the charger, it charges without problem.
                          Then if I unplug the charger and plug it back, it won't charge anymore.
                          In the first case, main voltage is regulated at ~12.5V and charges the battery.
                          After unplugging the charger, main voltage drops to battery voltage at ~11.5V.
                          After replugging the charger, main voltage stays at ~11.5V and won't go up to ~12.5V again.

                          I found C520A (2.2ยต after current sensor from USB-C source) completely burnt and removed it properly. I cleaned...

                          Thinkpad W541 (20EG) Q1, weird behavior after SPI flashing (3 flashes of power button LED)
                          by dj-bobr
                          Hi,
                          I kindly ask for help with Thinkpad BIOS/ME repair.
                          Thinkpad W541 board bought from Aliexpress, so I have no service tag nor S/N. It is 1GB version Q1 (K1100 nVidia GPU). BIOS 2.23, EC 1.13, ME 9.1.32.1002.
                          It worked fine until I tried to remove whitelist.

                          Steps taken:
                          - battery out, CMOS coin cell out, laptop disassembled; I kept LAN/USB subboard connected
                          - i took SPI programmer (CH341A with 3.3V mod) and SOIC clip and did a full backup of all SPI flash chips (SPI1 and SPI2 - BIOS, EC, ME, GbE; SPI3 - video BIOS; SPI4 - Thunderbolt fw) for several...
