lcd panel edid eeprom error m6700 in stock

I"m faced with an interesting issue! One of our client Dell laptop does not show POST/Dell splash screen when powered on. Eventually, after a minute or two, the Windows login screen appears. I"ve replaced the LCD panel, updated BIOS, drained power, reseated everything possible, and even re-imaged the HD. Dell diagnostics gives me this error: LCD EDID - Unable to access EDI EEPROM, even after replacing the LCD panel. I"m beginning to suspect that the motherboard is the culprit here. Anyone seen this type of issue before?Just out of curiosity, what does Dell Support have to say about that error?

SOLVED! I replaced the LVDS cable, and I am now able to see the Dell splash screen and also access BIOS and PXE boot. Diagnostics no longer reports an error. It"s a beautiful day - birds are chirping, flowers are blooming, people are happy. Thank you all for the support!!!

I also tried holding the "D" key and powering up. The LCD flashed a series of solid color screens (Red, Green, Blue, White, Black). I assume that this means that the backlight is good. Does it also mean that the cable is good?

Not sure what else to check. I am guessing that it is eiter the LCD screen (controller board) itself or the cable. Any advice? I am comfortable replacing parts.

The 24C04 is a 4K Bit EEPROM used to store monitor display control data. This memory is not directly accessible by the consumer; the adjustments are entered into the OSD menu, then the MCU writes the new data to the EEPROM. The information stored in the EEPROM is limited to specific parameters controlled by the monitor MCU.

The 24C02 is a 2K Bit EEPROM used to store monitor EDID information for use by the host PC. This information is written at the factory, and cannot be altered or deleted by the consumer.
